Thus, seafood consumption may cause long-term effects and health risk for consumers. In the present study, the occurrence of PhACs in seafood from two Brazilian coastal areas, Sepetiba Bay (n = 43) and Parnaiba Delta River (n = 48), was determined for the first time, and their potential risk for human health was assessed. An eco-friendly multi-analytes method was used, after being validated for the different types of matrices (mussels, fatty and lean fish). All compounds under study were detected at least in four seafood species, including chloramphenicol, an antibiotic prohibited in animal foods. Most PhACs had mean concentrations below limit of quantification. Ibuprofen and other nonsteroidal anti-inflammatory drugs (NSAIDs), as well as simvastatin and carbamazepine were the main PhACs bioaccumulated in edible parts of seafood species from Brazil. The high trophic level carnivorous species, snook, was the most contaminated by NSAIDs, while bivalves were the seafood more contaminated by lipid regulators. The profile of contamination did not vary among different types of matrix, except in relation to carbamazepine and ketoprofen. These PhACs were more abundant in species from Sepetiba Bay, an area highly impacted by human influence. The estimated daily exposure for Brazilian population that consumes the studied species was up to 20.3 ng/kg bw/day via carib pointed-venus and 25.7 ng/kg bw/day via snooks, lower than acceptable daily intake. Thus, consumption of seafood species from Sepetiba Bay and Parnaiba Delta River seems to be safe to the population in what concerns the PhACs studied.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="121753910"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="121753910"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 121753910; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=121753910]").text(description); $(".js-view-count[data-work-id=121753910]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 121753910; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='121753910']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 121753910, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=121753910]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":121753910,"title":"Occurrence of pharmaceuticals in seafood from two Brazilian coastal areas: Implication for human risk assessment","translated_title":"","metadata":{"abstract":"Pharmaceuticals (PhACs) are considered emerging contaminants with potential accumulation in aquatic organisms.

Thus, seafood consumption may cause long-term effects and health risk for consumers. In the present study, the occurrence of PhACs in seafood from two Brazilian coastal areas, Sepetiba Bay (n = 43) and Parnaiba Delta River (n = 48), was determined for the first time, and their potential risk for human health was assessed. An eco-friendly multi-analytes method was used, after being validated for the different types of matrices (mussels, fatty and lean fish). All compounds under study were detected at least in four seafood species, including chloramphenicol, an antibiotic prohibited in animal foods. Most PhACs had mean concentrations below limit of quantification. Ibuprofen and other nonsteroidal anti-inflammatory drugs (NSAIDs), as well as simvastatin and carbamazepine were the main PhACs bioaccumulated in edible parts of seafood species from Brazil. The high trophic level carnivorous species, snook, was the most contaminated by NSAIDs, while bivalves were the seafood more contaminated by lipid regulators. The profile of contamination did not vary among different types of matrix, except in relation to carbamazepine and ketoprofen. These PhACs were more abundant in species from Sepetiba Bay, an area highly impacted by human influence. The estimated daily exposure for Brazilian population that consumes the studied species was up to 20.3 ng/kg bw/day via carib pointed-venus and 25.7 ng/kg bw/day via snooks, lower than acceptable daily intake. Thus, consumption of seafood species from Sepetiba Bay and Parnaiba Delta River seems to be safe to the population in what concerns the PhACs studied.","internal_url":"https://www.academia.edu/121753910/Occurrence_of_pharmaceuticals_in_seafood_from_two_Brazilian_coastal_areas_Implication_for_human_risk_assessment","translated_internal_url":"","created_at":"2024-07-03T11:45:58.163-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[],"slug":"Occurrence_of_pharmaceuticals_in_seafood_from_two_Brazilian_coastal_areas_Implication_for_human_risk_assessment","translated_slug":"","page_count":null,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[],"research_interests":[{"id":26327,"name":"Medicine","url":"https://www.academia.edu/Documents/in/Medicine"},{"id":28235,"name":"Multidisciplinary","url":"https://www.academia.edu/Documents/in/Multidisciplinary"},{"id":154925,"name":"Trophic Level","url":"https://www.academia.edu/Documents/in/Trophic_Level"},{"id":1660649,"name":"Bay","url":"https://www.academia.edu/Documents/in/Bay"}],"urls":[{"id":43358891,"url":"https://doi.org/10.1016/j.scitotenv.2021.149744"}]}, dispatcherData: dispatcherData });

Neste contexto, enumeramos especificamente os principais trabalhos mundiais voltados à busca de nexo causal entre exposição a uma substância tóxica e alterações neurológicas. Ao longo do texto, relacionamos algumas variáveis ambientais sabidamente associadas a déficits cognitivos (anemia, parasitose, isolamento geográfico, desnutrição, exposições concomitantes despercebidas, etc.), bem como os principais testes psicométricos utilizados em estudos desta natureza (WISC-III, Desenho da Figura Humana, Boston Naming Test, etc.). Esperamos, com esta discussão, sugerir aos pesquisadores na área de neurotoxicologia a valorização de outros parâmetros ecológicos quando avaliarem efeitos de substâncias químicas presentes no ambiente, em especial, quando focarem populações não-urbanas, de baixo nível sócio-econômico e, em especial, aquelas mais isoladas geograficamente. palavras-chave: Neurotoxicologia, testes psicométricos, desnutrição, Amazônia. abstract ecologIcal Interferents on cognItIve evaluatIon of methylmercury exposed rIparIan chIldren: the weIght of the underdevelopment. This work reviewed several studies concerning negative effects of environmental pollutants (especially methylmercury) on human cognitive status and intelligence. Thus, we discuss the important worldwide research on the relation between exposure and quantifiable neurological performance loss. Along the text, we selected some human health and environmental factors which are known to be associated to cognitive deficits (anemia, parasites, geographic isolation, malnutrition, unknown concomitant exposures, etc.) as well as the main psychometric tests used in classical studies (WISC-III, Human Figure Drawing, Boston Naming Test, etc.). We hope, through this discussion, to suggest researchers who study neurotoxicology to be alert to other ecological parameters during their research on environmental chemical pollutants when they are surveying non-urban populations of low socioeconomic level conditions and, especially those under geographic isolation.","publication_date":{"day":13,"month":12,"year":2009,"errors":{}},"publication_name":"Oecologia Australis","grobid_abstract_attachment_id":116560557},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753909/Ecological_Interferents_on_Cognitive_Evaluation_of_Methylmercury_Exposed_Riparian_Children_The_Weight_of_the_Underdevelopment","translated_internal_url":"","created_at":"2024-07-03T11:45:57.869-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560557,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560557/thumbnails/1.jpg","file_name":"4258.pdf","download_url":"https://www.academia.edu/attachments/116560557/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Ecological_Interferents_on_Cognitive_Eva.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560557/4258-libre.pdf?1720035855=\u0026response-content-disposition=attachment%3B+filename%3DEcological_Interferents_on_Cognitive_Eva.pdf\u0026Expires=1733182941\u0026Signature=RHzt9j8eehhvBc5xsoTz42ORWESIcZdIHzGefNBIFjQBW9AtgNHQMRmbZyQE7of~Xt-QSuC28GdUfMW-hoDe6~mzoX-eoLNIihboKf01IM8bHj8ounChVzvjtocgxYH5-JIhiCE7HZl6ehb7XP78bZ1iGf3gltc0bX9XZVP9k1t89FKozN2~uhybgcSQjzU-UZgZYA4hOjEstSP27QNOrYLt6EqZn6N4ZkIp8dglRsdr6h-sBjSonO-wYvxPUPHKtHy~d7GfjItAzOLiK~VuoCgmrerFmnBVIacYMguHa11AVHedWQmzcrEV0ZDLh9HxMyAytPK0YlFL1hy1OhkWmg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Ecological_Interferents_on_Cognitive_Evaluation_of_Methylmercury_Exposed_Riparian_Children_The_Weight_of_the_Underdevelopment","translated_slug":"","page_count":20,"language":"pt","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560557,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560557/thumbnails/1.jpg","file_name":"4258.pdf","download_url":"https://www.academia.edu/attachments/116560557/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Ecological_Interferents_on_Cognitive_Eva.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560557/4258-libre.pdf?1720035855=\u0026response-content-disposition=attachment%3B+filename%3DEcological_Interferents_on_Cognitive_Eva.pdf\u0026Expires=1733182941\u0026Signature=RHzt9j8eehhvBc5xsoTz42ORWESIcZdIHzGefNBIFjQBW9AtgNHQMRmbZyQE7of~Xt-QSuC28GdUfMW-hoDe6~mzoX-eoLNIihboKf01IM8bHj8ounChVzvjtocgxYH5-JIhiCE7HZl6ehb7XP78bZ1iGf3gltc0bX9XZVP9k1t89FKozN2~uhybgcSQjzU-UZgZYA4hOjEstSP27QNOrYLt6EqZn6N4ZkIp8dglRsdr6h-sBjSonO-wYvxPUPHKtHy~d7GfjItAzOLiK~VuoCgmrerFmnBVIacYMguHa11AVHedWQmzcrEV0ZDLh9HxMyAytPK0YlFL1hy1OhkWmg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"},{"id":116560556,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560556/thumbnails/1.jpg","file_name":"4258.pdf","download_url":"https://www.academia.edu/attachments/116560556/download_file","bulk_download_file_name":"Ecological_Interferents_on_Cognitive_Eva.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560556/4258-libre.pdf?1720035849=\u0026response-content-disposition=attachment%3B+filename%3DEcological_Interferents_on_Cognitive_Eva.pdf\u0026Expires=1733182941\u0026Signature=As-ZHPSsYjDatwa~Dtrxjm-x3R-Jm2a9pFA87KoVtQqjiEVk8JJOno0pNidGg1esTkOiDpEv4BbPRXbo0exAb8~ATyjWhoNLWd4HWyNOQ4o7DIZnVDK703o2wKdxtGuG0Yjaoy55MsbWoZtX03TZZdmqrbQ-RYF71MKfAC9Xu8LO0NuAAmJZvnqbkVh~vjXTnsVf6CWAvGxZ317hdPHbNoW1KxrZpjlQk1Y8c5n4ErAedIgntbMWZ04QGQPqvK5F7uFczVhC7MejtczP63RnoyPdNuY9vbosw8aek8qWvBhyiFOpe1OUnjnDd9JE41XH597hBrGfwMzKQM-GCHQJkg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":261,"name":"Geography","url":"https://www.academia.edu/Documents/in/Geography"},{"id":4212,"name":"Cognition","url":"https://www.academia.edu/Documents/in/Cognition"},{"id":13298,"name":"Methylmercury","url":"https://www.academia.edu/Documents/in/Methylmercury"},{"id":1434261,"name":"Underdevelopment","url":"https://www.academia.edu/Documents/in/Underdevelopment"}],"urls":[{"id":43358890,"url":"https://revistas.ufrj.br/index.php/oa/article/download/5671/4258"}]}, dispatcherData: dispatcherData });

Whereas diffuse pollution occurs throughout the Piabanha river basin, the aim of this work was to evaluate the distribution of trace elements and persistent organic pollutants in its sediments over time and space, gathering information to assess the risks to the ecosystem and the population. And also to provide data to orient governmental institutions management of water resources in this region. The levels of organic pollutants highlight the influence of the historical use of pesticides in farming and industrial activities, mainly for Posse (203.36 ng/g dry weight) and Fagundes river (198.33 ng/g d.w) during the dry season and Moura Brazil (77.50 ng/g d.w) and Garagem (77.06 ng/g d.w) in the rainy season. In relation to available trace elements, the most contaminated locations were within and around Petrópolis center, possibly by industrial and domestic effluents, where Liceu (44-245 µg/g d.w) and Garagem (15-189 µg/g d.w) showed the highest concentrations of zinc. Furthermore, Liceu (5-58 µg/g d.w) also excelled in concentrations of lead. Cadmium was the element with major contribution to the contamination of the locations studied (Geoaccumulation index from 3 to 5 in all collected points), mainly because of its high mobility and the river flow. In addition, Poço do Ferreira river presented trace elements levels that exceeds the level 2 of the National Environment Council (CONAMA) classification. The authors highlight the need for a monitoring program on this region for the contaminants analyzed.","publication_date":{"day":null,"month":null,"year":2018,"errors":{}},"publication_name":"Orbital: The Electronic Journal of Chemistry","grobid_abstract_attachment_id":116560575},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753907/Current_State_of_Contamination_by_Persistent_Organic_Pollutants_and_Trace_Elements_on_Piabanha_River_Basin_Rio_de_Janeiro_Brazil","translated_internal_url":"","created_at":"2024-07-03T11:45:57.261-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560575,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560575/thumbnails/1.jpg","file_name":"6431feaf7a388b4b11e1759a228600cc9e93.pdf","download_url":"https://www.academia.edu/attachments/116560575/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Current_State_of_Contamination_by_Persis.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560575/6431feaf7a388b4b11e1759a228600cc9e93-libre.pdf?1720035822=\u0026response-content-disposition=attachment%3B+filename%3DCurrent_State_of_Contamination_by_Persis.pdf\u0026Expires=1733236830\u0026Signature=H5vAyBYQIJ1Edj2bo0RPE-QMRvJrCaenTANFtmeSAGaKpAhU7QC2goIbGJlYnT4iE-UxRYFDljwd~E5p-yCFsF4JQHrViuFByfOzW-fPnX6ROMCu6yMuhPc8pGCa1yvjG2bp4u0TUgVhnr5h~o-pKDqReZwwlFAMdV49xfbpWTbRCpHiEkNjLgclwYWdUYZnCAzvQ929pSLXk~NEkulFSDsWJu3JXliZfWJFhw8dyMAws~i4TDElCoVl61WdPocIsN0UOugYcNnw~e~kMFevTkemn71fWuzmc-a4jWFPzMxVSKpvYnc8a8CG6u99eBAqXqnhulKkiJh95mUq8CnrwQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Current_State_of_Contamination_by_Persistent_Organic_Pollutants_and_Trace_Elements_on_Piabanha_River_Basin_Rio_de_Janeiro_Brazil","translated_slug":"","page_count":10,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560575,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560575/thumbnails/1.jpg","file_name":"6431feaf7a388b4b11e1759a228600cc9e93.pdf","download_url":"https://www.academia.edu/attachments/116560575/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Current_State_of_Contamination_by_Persis.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560575/6431feaf7a388b4b11e1759a228600cc9e93-libre.pdf?1720035822=\u0026response-content-disposition=attachment%3B+filename%3DCurrent_State_of_Contamination_by_Persis.pdf\u0026Expires=1733236830\u0026Signature=H5vAyBYQIJ1Edj2bo0RPE-QMRvJrCaenTANFtmeSAGaKpAhU7QC2goIbGJlYnT4iE-UxRYFDljwd~E5p-yCFsF4JQHrViuFByfOzW-fPnX6ROMCu6yMuhPc8pGCa1yvjG2bp4u0TUgVhnr5h~o-pKDqReZwwlFAMdV49xfbpWTbRCpHiEkNjLgclwYWdUYZnCAzvQ929pSLXk~NEkulFSDsWJu3JXliZfWJFhw8dyMAws~i4TDElCoVl61WdPocIsN0UOugYcNnw~e~kMFevTkemn71fWuzmc-a4jWFPzMxVSKpvYnc8a8CG6u99eBAqXqnhulKkiJh95mUq8CnrwQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":402,"name":"Environmental Science","url":"https://www.academia.edu/Documents/in/Environmental_Science"},{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":198066,"name":"Contamination","url":"https://www.academia.edu/Documents/in/Contamination"},{"id":538342,"name":"Pollutant","url":"https://www.academia.edu/Documents/in/Pollutant"}],"urls":[]}, dispatcherData: dispatcherData });

Federal do Mato Grosso do Sul","grobid_abstract":"In 2009, human hair samples were collected in Brazilian sites historically contaminated with organochlorine to assess the level of contamination with DDT and its metabolites in local human populations (Santos and São Vicente Estuary-São Paulo State). 122 hair samples from members of four contaminated community were collected (Pilões and Água Fria, Cubatão Center, Continental São Vicente and Guarujá), along with one noncontaminated sample (Bertioga). DDT and its metabolites were detected in approximately 70.0% of the hair samples from all areas, and its concentrations ranged from 50.3 ng.g-1 to 141.8 ng.g-1 in Cubatão Center and Pilões and Água Fria, respectively. The highest p,p'-DDT concentration was detected in Pilões and Água Fria (134 ng.g-1) and, Cubatão Center (43.9 ng.g-1) exhibited the lowest concentration. There was not a clear association between the occurrence of evaluated diseases and DDT detection in hair. None of the locally produced groceries appeared to be risk factors for the presence of DDT in hair. However, DDT concentrations found in this study showed an increase of DDT available for human exposure. These results strengthen the evidence of current exposure routes between DDT and the population of the estuarine region; therefore, this issue deserves further investigation.","publication_date":{"day":null,"month":null,"year":2018,"errors":{}},"publication_name":"Orbital: The Electronic Journal of Chemistry","grobid_abstract_attachment_id":116560574},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753906/Determination_of_Environmental_Exposure_to_DDT_by_Human_Hair_Analysis_in_Santos_and_S%C3%A3o_Vicente_Estuary_S%C3%A3o_Paulo_Brazil","translated_internal_url":"","created_at":"2024-07-03T11:45:57.086-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560574,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560574/thumbnails/1.jpg","file_name":"pdf.pdf","download_url":"https://www.academia.edu/attachments/116560574/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Determination_of_Environmental_Exposure.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560574/pdf-libre.pdf?1720035812=\u0026response-content-disposition=attachment%3B+filename%3DDetermination_of_Environmental_Exposure.pdf\u0026Expires=1733236830\u0026Signature=E789Dh7M-R-3pasNeYeQBfiL71Obb~lw6J6GcNOuCA00V0K0-~axpleuYNh238kDBh0NZh-XK2Ma1pGIzR~udqMrEp6rQvCYeUEqTGwndiBKLuymCns9pALOanmZQwp-xalRFlZvY6~ESr2zkv6~HOFnwLpWnT59hgjsMOODMWch4FKiF3anWN1PoJoQDVqhaVKwStNLmpdZKDgy64lB3ZVuaVAvXdaQfsWUnF~s7HVq3IkxAPF4-d9s~44rHPXH5UW5Dleu2BXHtY89CPnwrQgwcSc6hUPurU6UOuFzx98Z8J6hVzPt0cVSEY6rflm-R~yELwmuMyBdRxE3FgYrGA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Determination_of_Environmental_Exposure_to_DDT_by_Human_Hair_Analysis_in_Santos_and_São_Vicente_Estuary_São_Paulo_Brazil","translated_slug":"","page_count":12,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560574,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560574/thumbnails/1.jpg","file_name":"pdf.pdf","download_url":"https://www.academia.edu/attachments/116560574/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Determination_of_Environmental_Exposure.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560574/pdf-libre.pdf?1720035812=\u0026response-content-disposition=attachment%3B+filename%3DDetermination_of_Environmental_Exposure.pdf\u0026Expires=1733236830\u0026Signature=E789Dh7M-R-3pasNeYeQBfiL71Obb~lw6J6GcNOuCA00V0K0-~axpleuYNh238kDBh0NZh-XK2Ma1pGIzR~udqMrEp6rQvCYeUEqTGwndiBKLuymCns9pALOanmZQwp-xalRFlZvY6~ESr2zkv6~HOFnwLpWnT59hgjsMOODMWch4FKiF3anWN1PoJoQDVqhaVKwStNLmpdZKDgy64lB3ZVuaVAvXdaQfsWUnF~s7HVq3IkxAPF4-d9s~44rHPXH5UW5Dleu2BXHtY89CPnwrQgwcSc6hUPurU6UOuFzx98Z8J6hVzPt0cVSEY6rflm-R~yELwmuMyBdRxE3FgYrGA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":379570,"name":"Estuary","url":"https://www.academia.edu/Documents/in/Estuary"}],"urls":[]}, dispatcherData: dispatcherData });

Both, OCPs and Hg, were widely used in the Brazilian Amazon region and deserve more attention in terms of environmental and public health. Focusing on expanding the knowledge about impacted areas and its consequences for local people, this study measured concentrations of OCPs and Hg in catfish (Ageneiosus brevifilis) samples. Moreover, a non-target analysis of organohalogen contaminants was carried out by means of full-scan screening. DDT and methylmercury showed the highest concentration values, ranging from 101 to 2061 µg kg-1 w.w. and 629 to 2009 µg kg-1 w.w., respectively. Pentachloroanisole was the only non-target organohalogenated compound identified and it was present in all samples. Estimated daily intake values did not exceed the safe reference limits proposed by the World Health Organization for OCPs, with the exception in some cases of heptachlor. On the other hand, the safe reference value of methylmercury was surpassed in all the fish samples. Results dismiss a recent input of OCPs due to greater contribution of pesticide metabolites, however, they point out a health risk hazard to riparian people. The concentrations of methylmercury and total dichlorodiphenyltrichloroethane, were up to one order of importance higher than other contaminants, which endorses that this region is still a hotspot for these contaminants.","publication_date":{"day":null,"month":null,"year":2018,"errors":{}},"publication_name":"Orbital: The Electronic Journal of Chemistry","grobid_abstract_attachment_id":116560577},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753905/Amazon_Riparian_People_s_Exposure_to_Legacy_Organochlorine_Pesticides_and_Methylmercury_from_Catfish_Ageneiosus_brevifilis_Intake","translated_internal_url":"","created_at":"2024-07-03T11:45:56.895-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560577,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560577/thumbnails/1.jpg","file_name":"518.pdf","download_url":"https://www.academia.edu/attachments/116560577/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Amazon_Riparian_People_s_Exposure_to_Leg.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560577/518-libre.pdf?1720035818=\u0026response-content-disposition=attachment%3B+filename%3DAmazon_Riparian_People_s_Exposure_to_Leg.pdf\u0026Expires=1733236830\u0026Signature=f5jwaStBkT2sc5ogve84A4NdZ-m5jADGnt6472G5JoyrBb5RvGQmX1J3kwA~gHQPBPdpWAiqAn3Sq-eAwnnVyiVsEt7mfY4pmbAy0Yues2OjIMz3hvnK48pyPxeraH4KfDR9QGrTU02rwCiQkZcZJiaP7cmltUFza9NOXHLa-kpwgceInhSvM4hLhEFE5lFh3JyplmPpka10fL2Hd2xd84t71nUPXjkpLZtiTJKKB5nDyAmGHbXSrUJ23eh1cK84w-9l4g92AJdO73FmPdCkd-dwb92fVGD-hvPzEJplCrUBkjf0-tbd2qc1A2foEQKPeY-JerBRbZh93jsykH~buQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Amazon_Riparian_People_s_Exposure_to_Legacy_Organochlorine_Pesticides_and_Methylmercury_from_Catfish_Ageneiosus_brevifilis_Intake","translated_slug":"","page_count":7,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560577,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560577/thumbnails/1.jpg","file_name":"518.pdf","download_url":"https://www.academia.edu/attachments/116560577/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Amazon_Riparian_People_s_Exposure_to_Leg.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560577/518-libre.pdf?1720035818=\u0026response-content-disposition=attachment%3B+filename%3DAmazon_Riparian_People_s_Exposure_to_Leg.pdf\u0026Expires=1733236830\u0026Signature=f5jwaStBkT2sc5ogve84A4NdZ-m5jADGnt6472G5JoyrBb5RvGQmX1J3kwA~gHQPBPdpWAiqAn3Sq-eAwnnVyiVsEt7mfY4pmbAy0Yues2OjIMz3hvnK48pyPxeraH4KfDR9QGrTU02rwCiQkZcZJiaP7cmltUFza9NOXHLa-kpwgceInhSvM4hLhEFE5lFh3JyplmPpka10fL2Hd2xd84t71nUPXjkpLZtiTJKKB5nDyAmGHbXSrUJ23eh1cK84w-9l4g92AJdO73FmPdCkd-dwb92fVGD-hvPzEJplCrUBkjf0-tbd2qc1A2foEQKPeY-JerBRbZh93jsykH~buQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":13298,"name":"Methylmercury","url":"https://www.academia.edu/Documents/in/Methylmercury"},{"id":65590,"name":"Pesticide","url":"https://www.academia.edu/Documents/in/Pesticide"},{"id":226114,"name":"Catfish","url":"https://www.academia.edu/Documents/in/Catfish"},{"id":373781,"name":"Amazon rainforest","url":"https://www.academia.edu/Documents/in/Amazon_rainforest"},{"id":3795346,"name":"Organochlorine pesticide","url":"https://www.academia.edu/Documents/in/Organochlorine_pesticide"}],"urls":[]}, dispatcherData: dispatcherData });

Due to long-range atmospheric transport, environmental persistence and toxicological potential of organochlorine pesticides (OCPs), similar characteristics of current-use pesticides (CUPs) and their massive use in Brazil, these contaminants have become a major concern for environmental and human life. Thus, this study aimed to evaluate subgroups or individual chemicals of OCPs and CUPs, which could have travelled over two Conservation Unit sites in the Rio de Janeiro state. The study was carried out for 24 months, (2013e2015), in Itatiaia National Park (INP) and in the Serra dos Orgãos National Park (SONP), at~2400 and~2200 meters above sea level, respectively. The study was based on atmospheric passive sampling (polyurethane foam disks). Target pesticides were detected by means of gas chromatography device coupled with mass spectrometry (GC-MS). Significantly higher concentrations were measured in SONP when compared to INP. However, in broad terms, the contamination profile was quite similar for both national parks: The highest concentrations of endosulfan (INP-1275 pg m À3 and SONP-3202 pg m À3) were followed by cypermethrin (INP-148 pg m À3 and SONP-881 pg m À3) and chlorpyrifos (INP-67 pg m À3 and SONP-270 pg m À3). In agreement with previous studies, the atmospheric concentrations of legacy OCPs showed background air levels. The decrease of endosulfan over the years was highlighted with a parallel increase of chlorpyrifos, suggesting a collateral effect of the national bias of permissive and massive use of agrochemicals. CUPs seemed to behave like pseudo-persistent pollutants (pseudo-POPs). This is the first report of atmospheric concentrations of pyrethroids in Brazilian mountain regions, and possibly the first to investigate them in the air in South America or in any mountain region in the world.","publication_date":{"day":null,"month":null,"year":2018,"errors":{}},"publication_name":"Environmental Pollution","grobid_abstract_attachment_id":116560576},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753904/Air_contamination_by_legacy_and_current_use_pesticides_in_Brazilian_mountains_An_overview_of_national_regulations_by_monitoring_pollutant_presence_in_pristine_areas","translated_internal_url":"","created_at":"2024-07-03T11:45:56.640-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560576,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560576/thumbnails/1.jpg","file_name":"Guida_et_al.2c_2018_-ENPO.pdf","download_url":"https://www.academia.edu/attachments/116560576/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Air_contamination_by_legacy_and_current.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560576/Guida_et_al.2c_2018_-ENPO-libre.pdf?1720035817=\u0026response-content-disposition=attachment%3B+filename%3DAir_contamination_by_legacy_and_current.pdf\u0026Expires=1733236830\u0026Signature=gfRGifMGo6HstPZOGeSDjEwGg9BLSWgxdNFeCBYTtGzJd9WMlDJn3V23vj2-nl6U5i4DlHgYafhI-eJj9iVuEYAsUvZVDufF5E29yDwNvZZD9cImAw7rJVGUk20Y3T0uv88dipyDFomwXMuHBzLAF02Q2X82KcY53WBAgJKQ~I9pc1LtNMbUPVNqpQ2Oppso7W3QDAQ~VcRm63DDcnJKurY~DVZxihQePNm0EiV7kdmTLixs1KINVJLBTKxHGj06Q7yEPz~pjM2VBjK1naRgvge-5s~Zl1GDzXZgyvKk4WU9CR-8RbqpZ2aVbBwgNsMfcCFyWcnV3SePmFrgbylGnQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Air_contamination_by_legacy_and_current_use_pesticides_in_Brazilian_mountains_An_overview_of_national_regulations_by_monitoring_pollutant_presence_in_pristine_areas","translated_slug":"","page_count":12,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560576,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560576/thumbnails/1.jpg","file_name":"Guida_et_al.2c_2018_-ENPO.pdf","download_url":"https://www.academia.edu/attachments/116560576/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Air_contamination_by_legacy_and_current.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560576/Guida_et_al.2c_2018_-ENPO-libre.pdf?1720035817=\u0026response-content-disposition=attachment%3B+filename%3DAir_contamination_by_legacy_and_current.pdf\u0026Expires=1733236830\u0026Signature=gfRGifMGo6HstPZOGeSDjEwGg9BLSWgxdNFeCBYTtGzJd9WMlDJn3V23vj2-nl6U5i4DlHgYafhI-eJj9iVuEYAsUvZVDufF5E29yDwNvZZD9cImAw7rJVGUk20Y3T0uv88dipyDFomwXMuHBzLAF02Q2X82KcY53WBAgJKQ~I9pc1LtNMbUPVNqpQ2Oppso7W3QDAQ~VcRm63DDcnJKurY~DVZxihQePNm0EiV7kdmTLixs1KINVJLBTKxHGj06Q7yEPz~pjM2VBjK1naRgvge-5s~Zl1GDzXZgyvKk4WU9CR-8RbqpZ2aVbBwgNsMfcCFyWcnV3SePmFrgbylGnQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":402,"name":"Environmental Science","url":"https://www.academia.edu/Documents/in/Environmental_Science"},{"id":15836,"name":"Environmental Chemistry","url":"https://www.academia.edu/Documents/in/Environmental_Chemistry"},{"id":25445,"name":"Environmental Pollution","url":"https://www.academia.edu/Documents/in/Environmental_Pollution"},{"id":26327,"name":"Medicine","url":"https://www.academia.edu/Documents/in/Medicine"},{"id":28235,"name":"Multidisciplinary","url":"https://www.academia.edu/Documents/in/Multidisciplinary"},{"id":65590,"name":"Pesticide","url":"https://www.academia.edu/Documents/in/Pesticide"},{"id":167983,"name":"Endosulfan","url":"https://www.academia.edu/Documents/in/Endosulfan"},{"id":198066,"name":"Contamination","url":"https://www.academia.edu/Documents/in/Contamination"},{"id":284869,"name":"National Park","url":"https://www.academia.edu/Documents/in/National_Park"},{"id":764674,"name":"Chlorpyrifos","url":"https://www.academia.edu/Documents/in/Chlorpyrifos"}],"urls":[{"id":43358888,"url":"https://api.elsevier.com/content/article/PII:S0269749118314441?httpAccept=text/xml"}]}, dispatcherData: dispatcherData });

However, little is known regarding aeration effects in suspended particulate aggregates. Therefore, this study aimed to investigate the effects of aeration on the suspended matter from a Tropical and Eutrophic estuarine environment. Anoxic water with 60 g/L of suspended particulate matter (SPM) was collected from Guanabara Bay, Rio de Janeiro, Brazil, transferred to experimental boxes and aerated for 61 days. SPM aggregates monitoring included abiotic variables measurements and, determination of total organic matter (TOM), biopolymers composition, bacterial activity, trace metals, and polycyclic aromatic hydrocarbons (PAHs) concentrations. The aeration enhanced dissolved oxygen (DO) concentration and the redox potential (Eh). However, from days 0 to 61 the predominant bacterial activities were denitrification and fermentation. Electron transport system activity increased after day 10, and aerobic activity was detected after day 19. In summary, aeration increased aerobic bacterial activity, lipids (LIP) and trace metal concentrations, although diminished protein/carbohydrate ratio and PAH concentration. Trace metals concentration (Ni, Pb, Cu, Cr, Mn, and Fe) were the highest on day 19 when the pH was 5.9. Copper presented toxic values (Cu \u003e 20.0 μg/g). The pH showed a strong negative correlation with Eh (r = − 0.94; p \u003c 0.001). Acidic environment (pH ≤ 5.9) in marine ecosystems with high loads of toxic trace metals is unsafe for biota. Therefore, managers must be aware of the environmental and biological risks of introducing the aeration technique into a eutrophic marine environment.","publication_date":{"day":null,"month":null,"year":2019,"errors":{}},"publication_name":"Journal of Environmental Sciences","grobid_abstract_attachment_id":116560573},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753903/Effects_of_aeration_on_the_suspended_matter_from_a_tropical_and_eutrophic_estuary","translated_internal_url":"","created_at":"2024-07-03T11:45:56.386-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560573,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560573/thumbnails/1.jpg","file_name":"create_pdf.pdf","download_url":"https://www.academia.edu/attachments/116560573/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Effects_of_aeration_on_the_suspended_mat.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560573/create_pdf-libre.pdf?1720035827=\u0026response-content-disposition=attachment%3B+filename%3DEffects_of_aeration_on_the_suspended_mat.pdf\u0026Expires=1733236830\u0026Signature=HcfwKw7rxlMJJ6vUXULiBaq5qxKDCmjH~IyeEOVILBpRQ-Pn4bRzyShPOlEFcdlU8~PdqUl1lIVbuDvwnxQNdKRD6wmSVqQZH-l2VamG5xB0vrSQNZfmnAhQ9fsm0tStzMB4iXZPRbIjBwZqI0eKbOi9szJZ~xa-e2rX-GihNhU1LFcQ8rDtohFlp98E6e7szc8fBer-3PlV8-QyyD35eQq~46uGJmJmVHx47P~ZTHT~yAM4zLXROG-LYf0MnZKciAxrOaI8F5crGZrTFJqdf4ihXHwDtj6K63OFNJqI2zbbC3loURjghBT3sLoXphNwbJLRRXvfxkWTkQ3NqP6kdg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Effects_of_aeration_on_the_suspended_matter_from_a_tropical_and_eutrophic_estuary","translated_slug":"","page_count":12,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560573,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560573/thumbnails/1.jpg","file_name":"create_pdf.pdf","download_url":"https://www.academia.edu/attachments/116560573/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Effects_of_aeration_on_the_suspended_mat.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560573/create_pdf-libre.pdf?1720035827=\u0026response-content-disposition=attachment%3B+filename%3DEffects_of_aeration_on_the_suspended_mat.pdf\u0026Expires=1733236830\u0026Signature=HcfwKw7rxlMJJ6vUXULiBaq5qxKDCmjH~IyeEOVILBpRQ-Pn4bRzyShPOlEFcdlU8~PdqUl1lIVbuDvwnxQNdKRD6wmSVqQZH-l2VamG5xB0vrSQNZfmnAhQ9fsm0tStzMB4iXZPRbIjBwZqI0eKbOi9szJZ~xa-e2rX-GihNhU1LFcQ8rDtohFlp98E6e7szc8fBer-3PlV8-QyyD35eQq~46uGJmJmVHx47P~ZTHT~yAM4zLXROG-LYf0MnZKciAxrOaI8F5crGZrTFJqdf4ihXHwDtj6K63OFNJqI2zbbC3loURjghBT3sLoXphNwbJLRRXvfxkWTkQ3NqP6kdg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":400,"name":"Earth Sciences","url":"https://www.academia.edu/Documents/in/Earth_Sciences"},{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":15836,"name":"Environmental Chemistry","url":"https://www.academia.edu/Documents/in/Environmental_Chemistry"},{"id":26181,"name":"Eutrophication","url":"https://www.academia.edu/Documents/in/Eutrophication"},{"id":26327,"name":"Medicine","url":"https://www.academia.edu/Documents/in/Medicine"},{"id":58054,"name":"Environmental Sciences","url":"https://www.academia.edu/Documents/in/Environmental_Sciences"},{"id":172487,"name":"Airborne Particulates","url":"https://www.academia.edu/Documents/in/Airborne_Particulates"},{"id":260118,"name":"CHEMICAL SCIENCES","url":"https://www.academia.edu/Documents/in/CHEMICAL_SCIENCES"},{"id":379570,"name":"Estuary","url":"https://www.academia.edu/Documents/in/Estuary"},{"id":803011,"name":"Aeration","url":"https://www.academia.edu/Documents/in/Aeration"},{"id":970387,"name":"Organic Matter","url":"https://www.academia.edu/Documents/in/Organic_Matter"}],"urls":[{"id":43358887,"url":"https://api.elsevier.com/content/article/PII:S1001074219304899?httpAccept=text/xml"}]}, dispatcherData: dispatcherData });

Low density polyethylene passive samplers were deployed in upland surface waters and the overlying atmosphere in subtropical and tropical mountain regions in south and southeast Brazil, respectively, to determine the concentrations, transport and sources of freely dissolved and gaseous polycyclic aromatic hydrocarbons (PAHs) along altitudinal gradients. Gaseous PAH concentrations (0.70-90 ng.m-3) were dominated by phenanthrene and fluorene, though methylnaphthalenes displayed high concentrations at upland sites. Fluoranthene and chrysene were the most frequently detected PAHs in shallow waters (10-110 pg.L-1). Individual PAHs indicated a wood/grass combustion origin at both national parks due to current and historical man-made fires, with a minor petrogenic fingerprint, probably due to the proximity of highway traffic and touristic activities. A slightly increasing trend of 2-3 ring PAHs was observed along tropical elevation transect which may reflect longrange atmospheric transport of more volatile PAHs over tropical elevated altitudes. However, local PAH emission sources probably explain the opposite trend detected at subtropical elevation transect.","publication_date":{"day":null,"month":null,"year":2018,"errors":{}},"publication_name":"Atmospheric Pollution Research","grobid_abstract_attachment_id":116560572},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753902/Passive_sampler_derived_concentrations_of_PAHs_in_air_and_water_along_Brazilian_mountain_transects","translated_internal_url":"","created_at":"2024-07-03T11:45:56.144-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560572,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560572/thumbnails/1.jpg","file_name":"1-s2.0-S1309104218303878-main.pdf","download_url":"https://www.academia.edu/attachments/116560572/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Passive_sampler_derived_concentrations_o.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560572/1-s2.0-S1309104218303878-main-libre.pdf?1720035822=\u0026response-content-disposition=attachment%3B+filename%3DPassive_sampler_derived_concentrations_o.pdf\u0026Expires=1733236830\u0026Signature=PxaKqlhM~lQczHkTWz2j3XDYtXLgOPmxZbgaNEYS57TFM2h530P0dZ6eZd1CbH5h81CmLS72LnuuyiqXn8FllDJ9kPzIeSwTZJJNGi5fiOWyHvq0fKZaE-qEitn7GikUeMr4e9Ht0aPxNTex9vgyWD9L4qxuOd29ifAoLgOclr37U6yox-LkR2N272yrtK25050MskqIc6NlPmTuFlFu2w7OYmSeANihtAXI0zGCU0Q-TDOAu2rFEsbqaMXi6lLc32kCLdc7W9E-bFhfH8LsbrZmYsbvA9KsyIGzaQqf8HiCfFOaDMVXKDH2afHm057ZhZJLiHnvy9UzabrVk~OPdw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Passive_sampler_derived_concentrations_of_PAHs_in_air_and_water_along_Brazilian_mountain_transects","translated_slug":"","page_count":34,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560572,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560572/thumbnails/1.jpg","file_name":"1-s2.0-S1309104218303878-main.pdf","download_url":"https://www.academia.edu/attachments/116560572/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Passive_sampler_derived_concentrations_o.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560572/1-s2.0-S1309104218303878-main-libre.pdf?1720035822=\u0026response-content-disposition=attachment%3B+filename%3DPassive_sampler_derived_concentrations_o.pdf\u0026Expires=1733236830\u0026Signature=PxaKqlhM~lQczHkTWz2j3XDYtXLgOPmxZbgaNEYS57TFM2h530P0dZ6eZd1CbH5h81CmLS72LnuuyiqXn8FllDJ9kPzIeSwTZJJNGi5fiOWyHvq0fKZaE-qEitn7GikUeMr4e9Ht0aPxNTex9vgyWD9L4qxuOd29ifAoLgOclr37U6yox-LkR2N272yrtK25050MskqIc6NlPmTuFlFu2w7OYmSeANihtAXI0zGCU0Q-TDOAu2rFEsbqaMXi6lLc32kCLdc7W9E-bFhfH8LsbrZmYsbvA9KsyIGzaQqf8HiCfFOaDMVXKDH2afHm057ZhZJLiHnvy9UzabrVk~OPdw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":402,"name":"Environmental Science","url":"https://www.academia.edu/Documents/in/Environmental_Science"},{"id":15836,"name":"Environmental Chemistry","url":"https://www.academia.edu/Documents/in/Environmental_Chemistry"},{"id":162644,"name":"Transect","url":"https://www.academia.edu/Documents/in/Transect"},{"id":216113,"name":"Atmospheric pollution","url":"https://www.academia.edu/Documents/in/Atmospheric_pollution"},{"id":772819,"name":"Phenanthrene","url":"https://www.academia.edu/Documents/in/Phenanthrene"},{"id":976496,"name":"Fluoranthene","url":"https://www.academia.edu/Documents/in/Fluoranthene"},{"id":1872418,"name":"Subtropics","url":"https://www.academia.edu/Documents/in/Subtropics"}],"urls":[{"id":43358886,"url":"https://api.elsevier.com/content/article/PII:S1309104218303878?httpAccept=text/xml"}]}, dispatcherData: dispatcherData });

Air, soil, and atmospheric deposition process in the Pearl River Delta of South China were investigated, and the average SCCP and MCCP concentrations were 5.2 μg/sampler (17.69 ng/m 3) and 4.1 μg/sampler for passive air samples, 18.3 and 59.3 ng/g for soil samples, and 5.0 and 5.3 μg/(m 2 d) for deposition samples, respectively. Influenced by primary sources and the properties of chlorinated paraffins (CPs), a gradient trend of concentrations and a fractionation of composition from more to less industrialized areas were discovered. Intense seasonal variations with high levels in summer air and winter deposition samples indicated that the air and deposition CP levels were controlled mainly by the vapor and particle phase, respectively. Complex environmental processes like volatilization and fractionation resulted in different CP profiles in different environment matrixes and sampling locations, with C 10−11 Cl 6−7 and C 14 Cl 6−7 , C 10−12 Cl 6−7 and C 14 Cl 6−8 , and C 11−12 Cl 6−8 and C 14 Cl 7−8 dominating in air, soil, and atmospheric deposition, respectively. Shorter-chain and less chlorinated congeners were enriched in air in the less industrialized areas, while longer-chain and higher chlorinated congeners were concentrated in soil in the more industrialized areas. This is suggesting that the gaseous transport of CPs is the dominant mechanism responsible for the higher concentrations of lighter and likely more mobile CPs in the rural areas.","publication_date":{"day":null,"month":null,"year":2013,"errors":{}},"publication_name":"Environmental Science \u0026amp;

Concentrations of Hg did not differ significantly between museum specimens and live individuals of P. onca, but varied significantly among species, with significantly higher concentrations for P. onca and L. pardalis, which could be related to factors such as diet and habitat.","internal_url":"https://www.academia.edu/118435714/Total_mercury_in_wild_felids_occurring_in_protected_areas_in_the_central_Brazilian_Amazon","translated_internal_url":"","created_at":"2024-05-02T07:11:02.491-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":114063303,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/114063303/thumbnails/1.jpg","file_name":"0044-5967-aa-50-02-142.pdf","download_url":"https://www.academia.edu/attachments/114063303/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Total_mercury_in_wild_felids_occurring_i.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/114063303/0044-5967-aa-50-02-142-libre.pdf?1714662823=\u0026response-content-disposition=attachment%3B+filename%3DTotal_mercury_in_wild_felids_occurring_i.pdf\u0026Expires=1733236831\u0026Signature=KwHQSN4K3coGf9KWwfcQty1MzIhF7PQTLFBzJvYZkHS4Nc8hp034zf8R71q9PbOLtXWeMNCC6X2XSy2WsEoXgm5HUq72EsfY6qVYlSX6L23N926TEEqZz-ae2yEDNK12JuksQBZmE7veRm9Lfq5gM4SCsKv8O3Aj8H5kzaZJjPY~mJB~jC9g3Bh8cVGBF4aYN7t9Vq7k0f5XhStlQfKb4cPPwxL9HXrbDIh5Y5G1SyENzlCVyMNdhx5txSbIvDZmUtbB20sJjrSx2Y1CBZHGW7ftFnjnsRUIbpazTjm4EDAAwj5ODLuwidICPdXGI6ePQv9hFdmSYm-~0HlIOoDOWw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Total_mercury_in_wild_felids_occurring_in_protected_areas_in_the_central_Brazilian_Amazon","translated_slug":"","page_count":8,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":114063303,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/114063303/thumbnails/1.jpg","file_name":"0044-5967-aa-50-02-142.pdf","download_url":"https://www.academia.edu/attachments/114063303/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Total_mercury_in_wild_felids_occurring_i.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/114063303/0044-5967-aa-50-02-142-libre.pdf?1714662823=\u0026response-content-disposition=attachment%3B+filename%3DTotal_mercury_in_wild_felids_occurring_i.pdf\u0026Expires=1733236831\u0026Signature=KwHQSN4K3coGf9KWwfcQty1MzIhF7PQTLFBzJvYZkHS4Nc8hp034zf8R71q9PbOLtXWeMNCC6X2XSy2WsEoXgm5HUq72EsfY6qVYlSX6L23N926TEEqZz-ae2yEDNK12JuksQBZmE7veRm9Lfq5gM4SCsKv8O3Aj8H5kzaZJjPY~mJB~jC9g3Bh8cVGBF4aYN7t9Vq7k0f5XhStlQfKb4cPPwxL9HXrbDIh5Y5G1SyENzlCVyMNdhx5txSbIvDZmUtbB20sJjrSx2Y1CBZHGW7ftFnjnsRUIbpazTjm4EDAAwj5ODLuwidICPdXGI6ePQv9hFdmSYm-~0HlIOoDOWw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"},{"id":114063304,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/114063304/thumbnails/1.jpg","file_name":"0044-5967-aa-50-02-142.pdf","download_url":"https://www.academia.edu/attachments/114063304/download_file","bulk_download_file_name":"Total_mercury_in_wild_felids_occurring_i.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/114063304/0044-5967-aa-50-02-142-libre.pdf?1714662826=\u0026response-content-disposition=attachment%3B+filename%3DTotal_mercury_in_wild_felids_occurring_i.pdf\u0026Expires=1733236831\u0026Signature=PJQUbkyswf6IgXD1wWl8Uqrpiz0iynZZLnyEtcpwFsD941gfA2Qh-FHB~l2Ujx9SffGGjWI4JZlgCF9YBc8YWJyg4XvALmSR5UYeiK1Ijmg5goMtcYqlTehEgTBcWw8RcWxhlyb5VlUzpVnSXqP~xkNfhQm65D-eiPjSDQQ1RVDtW82qP5bv4vzRMZ9mNP5bLrjRoqa3sAEWbKH41~X1HCcHaNbAoUoxg8kUGIXyAc7UsdwQXZ-7g75lWLWh4~MuuCjG9jy0HgF14qVXA0AgiF5Nr3V4-tXu19CInW1jKX~y0lyInkUjzPju5h12m3qAAjvNe4iR60QxQIb44FjDmw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":261,"name":"Geography","url":"https://www.academia.edu/Documents/in/Geography"},{"id":260408,"name":"Jaguar","url":"https://www.academia.edu/Documents/in/Jaguar"},{"id":373781,"name":"Amazon rainforest","url":"https://www.academia.edu/Documents/in/Amazon_rainforest"},{"id":763188,"name":"Camera Trap","url":"https://www.academia.edu/Documents/in/Camera_Trap"},{"id":1029192,"name":"Leopardus","url":"https://www.academia.edu/Documents/in/Leopardus"}],"urls":[{"id":41584512,"url":"http://www.scielo.br/pdf/aa/v50n2/0044-5967-aa-50-02-142.pdf"}]}, dispatcherData: dispatcherData });

Inhabitants living along the river who relied mainly on Doce river's water supply for agriculture and human consumption faced risk from the mining residue exposure. This study aimed to investigate the disaster's impact on small family farmers living in Minas Gerais and Espírito Santo States by water elemental quantification and evaluate the potential pathways of contamination by survey. In July 2016, 48 water points-including well, river and public distributed water-of 3 cities (Belo Oriente, Governador Valadares and Colatina) were sampled for determination of As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Sn and Zn elements. Ninety-eight percent of the inhabitants interviewed related Doce river water usage before the tragedy for diversified purposes, while only thirty-six per cent used it after the disaster, mainly for irrigation. Fe and Mn presented concentrations above the Brazilian legislation for drinking water and irrigation in all locations, but not in all samples. Pb concentration was above the drinking water legislation in one location. All the other elements concentrations were within safe limits. Colatina, the farthest city from the dam, presented the highest values, followed by Governador Valadares and Belo Oriente.","publication_date":{"day":null,"month":null,"year":2018,"errors":{}},"publication_name":"Orbital: The Electronic Journal of Chemistry","grobid_abstract_attachment_id":114063354},"translated_abstract":null,"internal_url":"https://www.academia.edu/118435712/Metals_and_Arsenic_in_Water_Supply_for_Riverine_Communities_Affected_by_the_Largest_Environmental_Disaster_in_Brazil_The_Dam_Collapse_on_Doce_River","translated_internal_url":"","created_at":"2024-05-02T07:11:01.613-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":114063354,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/114063354/thumbnails/1.jpg","file_name":"eaa404a3f20b2ddf97d8249dd9ee5ad19650.pdf","download_url":"https://www.academia.edu/attachments/114063354/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Metals_and_Arsenic_in_Water_Supply_for_R.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/114063354/eaa404a3f20b2ddf97d8249dd9ee5ad19650-libre.pdf?1714662827=\u0026response-content-disposition=attachment%3B+filename%3DMetals_and_Arsenic_in_Water_Supply_for_R.pdf\u0026Expires=1733236831\u0026Signature=M5F0mZk9RYoHCY5~z~Jeg-efpsMz~K62vBiQyIyN-NoCjPFoelo4SVAcN~XJy1GlO7LJP~pj~Sf81C22LDgfWrPCpv9ytdEj00otSuR2tC75ckIe5MnSqwew1nphw3TExgzBq3vdU81U0BA7A5I-xatmIWt-n75d8zTB6bdEe4rpK~Rmvnihc7xxTusUaVqmgc0s2L8eo-FZ2BZyPoPzi~YgqwNXEQ72IN1-d1QMXZ5UaDWDJpjyEG-GJYpxFWcNgSgB1gqdZhrVZAX~NTEve1yVObedIatG0xu211qfQV77pmMcJrJMgZmKGJDSSa60J~AzBhJ47oF0Jc5yyr63cQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Metals_and_Arsenic_in_Water_Supply_for_Riverine_Communities_Affected_by_the_Largest_Environmental_Disaster_in_Brazil_The_Dam_Collapse_on_Doce_River","translated_slug":"","page_count":9,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":114063354,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/114063354/thumbnails/1.jpg","file_name":"eaa404a3f20b2ddf97d8249dd9ee5ad19650.pdf","download_url":"https://www.academia.edu/attachments/114063354/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Metals_and_Arsenic_in_Water_Supply_for_R.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/114063354/eaa404a3f20b2ddf97d8249dd9ee5ad19650-libre.pdf?1714662827=\u0026response-content-disposition=attachment%3B+filename%3DMetals_and_Arsenic_in_Water_Supply_for_R.pdf\u0026Expires=1733236831\u0026Signature=M5F0mZk9RYoHCY5~z~Jeg-efpsMz~K62vBiQyIyN-NoCjPFoelo4SVAcN~XJy1GlO7LJP~pj~Sf81C22LDgfWrPCpv9ytdEj00otSuR2tC75ckIe5MnSqwew1nphw3TExgzBq3vdU81U0BA7A5I-xatmIWt-n75d8zTB6bdEe4rpK~Rmvnihc7xxTusUaVqmgc0s2L8eo-FZ2BZyPoPzi~YgqwNXEQ72IN1-d1QMXZ5UaDWDJpjyEG-GJYpxFWcNgSgB1gqdZhrVZAX~NTEve1yVObedIatG0xu211qfQV77pmMcJrJMgZmKGJDSSa60J~AzBhJ47oF0Jc5yyr63cQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":6227,"name":"Arsenic","url":"https://www.academia.edu/Documents/in/Arsenic"},{"id":64055,"name":"Water Supply","url":"https://www.academia.edu/Documents/in/Water_Supply"},{"id":156376,"name":"Water resource management","url":"https://www.academia.edu/Documents/in/Water_resource_management"},{"id":853578,"name":"Environmental Disaster","url":"https://www.academia.edu/Documents/in/Environmental_Disaster"}],"urls":[]}, dispatcherData: dispatcherData });

To assess the evolutionary history between these species, 67 DNA samples were sequenced for AK1 locus, 70 samples for RAG1 locus and 96 samples for Cytb locus, sampling in King George and Elephant Island. Cytb and RAG1 loci showed greater genetic diversity in samples from hybrid birds than those of non-hybrid individuals and may reflect the outcome of the heterosis.

Thus, seafood consumption may cause long-term effects and health risk for consumers. In the present study, the occurrence of PhACs in seafood from two Brazilian coastal areas, Sepetiba Bay (n = 43) and Parnaiba Delta River (n = 48), was determined for the first time, and their potential risk for human health was assessed. An eco-friendly multi-analytes method was used, after being validated for the different types of matrices (mussels, fatty and lean fish). All compounds under study were detected at least in four seafood species, including chloramphenicol, an antibiotic prohibited in animal foods. Most PhACs had mean concentrations below limit of quantification. Ibuprofen and other nonsteroidal anti-inflammatory drugs (NSAIDs), as well as simvastatin and carbamazepine were the main PhACs bioaccumulated in edible parts of seafood species from Brazil. The high trophic level carnivorous species, snook, was the most contaminated by NSAIDs, while bivalves were the seafood more contaminated by lipid regulators. The profile of contamination did not vary among different types of matrix, except in relation to carbamazepine and ketoprofen. These PhACs were more abundant in species from Sepetiba Bay, an area highly impacted by human influence. The estimated daily exposure for Brazilian population that consumes the studied species was up to 20.3 ng/kg bw/day via carib pointed-venus and 25.7 ng/kg bw/day via snooks, lower than acceptable daily intake. Thus, consumption of seafood species from Sepetiba Bay and Parnaiba Delta River seems to be safe to the population in what concerns the PhACs studied.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="121753910"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="121753910"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 121753910; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=121753910]").text(description); $(".js-view-count[data-work-id=121753910]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 121753910; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='121753910']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 121753910, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=121753910]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":121753910,"title":"Occurrence of pharmaceuticals in seafood from two Brazilian coastal areas: Implication for human risk assessment","translated_title":"","metadata":{"abstract":"Pharmaceuticals (PhACs) are considered emerging contaminants with potential accumulation in aquatic organisms.

Neste contexto, enumeramos especificamente os principais trabalhos mundiais voltados à busca de nexo causal entre exposição a uma substância tóxica e alterações neurológicas. Ao longo do texto, relacionamos algumas variáveis ambientais sabidamente associadas a déficits cognitivos (anemia, parasitose, isolamento geográfico, desnutrição, exposições concomitantes despercebidas, etc.), bem como os principais testes psicométricos utilizados em estudos desta natureza (WISC-III, Desenho da Figura Humana, Boston Naming Test, etc.). Esperamos, com esta discussão, sugerir aos pesquisadores na área de neurotoxicologia a valorização de outros parâmetros ecológicos quando avaliarem efeitos de substâncias químicas presentes no ambiente, em especial, quando focarem populações não-urbanas, de baixo nível sócio-econômico e, em especial, aquelas mais isoladas geograficamente. palavras-chave: Neurotoxicologia, testes psicométricos, desnutrição, Amazônia. abstract ecologIcal Interferents on cognItIve evaluatIon of methylmercury exposed rIparIan chIldren: the weIght of the underdevelopment. This work reviewed several studies concerning negative effects of environmental pollutants (especially methylmercury) on human cognitive status and intelligence. Thus, we discuss the important worldwide research on the relation between exposure and quantifiable neurological performance loss. Along the text, we selected some human health and environmental factors which are known to be associated to cognitive deficits (anemia, parasites, geographic isolation, malnutrition, unknown concomitant exposures, etc.) as well as the main psychometric tests used in classical studies (WISC-III, Human Figure Drawing, Boston Naming Test, etc.). We hope, through this discussion, to suggest researchers who study neurotoxicology to be alert to other ecological parameters during their research on environmental chemical pollutants when they are surveying non-urban populations of low socioeconomic level conditions and, especially those under geographic isolation.","publication_date":{"day":13,"month":12,"year":2009,"errors":{}},"publication_name":"Oecologia Australis","grobid_abstract_attachment_id":116560557},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753909/Ecological_Interferents_on_Cognitive_Evaluation_of_Methylmercury_Exposed_Riparian_Children_The_Weight_of_the_Underdevelopment","translated_internal_url":"","created_at":"2024-07-03T11:45:57.869-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560557,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560557/thumbnails/1.jpg","file_name":"4258.pdf","download_url":"https://www.academia.edu/attachments/116560557/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Ecological_Interferents_on_Cognitive_Eva.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560557/4258-libre.pdf?1720035855=\u0026response-content-disposition=attachment%3B+filename%3DEcological_Interferents_on_Cognitive_Eva.pdf\u0026Expires=1733182941\u0026Signature=RHzt9j8eehhvBc5xsoTz42ORWESIcZdIHzGefNBIFjQBW9AtgNHQMRmbZyQE7of~Xt-QSuC28GdUfMW-hoDe6~mzoX-eoLNIihboKf01IM8bHj8ounChVzvjtocgxYH5-JIhiCE7HZl6ehb7XP78bZ1iGf3gltc0bX9XZVP9k1t89FKozN2~uhybgcSQjzU-UZgZYA4hOjEstSP27QNOrYLt6EqZn6N4ZkIp8dglRsdr6h-sBjSonO-wYvxPUPHKtHy~d7GfjItAzOLiK~VuoCgmrerFmnBVIacYMguHa11AVHedWQmzcrEV0ZDLh9HxMyAytPK0YlFL1hy1OhkWmg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Ecological_Interferents_on_Cognitive_Evaluation_of_Methylmercury_Exposed_Riparian_Children_The_Weight_of_the_Underdevelopment","translated_slug":"","page_count":20,"language":"pt","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560557,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560557/thumbnails/1.jpg","file_name":"4258.pdf","download_url":"https://www.academia.edu/attachments/116560557/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Ecological_Interferents_on_Cognitive_Eva.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560557/4258-libre.pdf?1720035855=\u0026response-content-disposition=attachment%3B+filename%3DEcological_Interferents_on_Cognitive_Eva.pdf\u0026Expires=1733182941\u0026Signature=RHzt9j8eehhvBc5xsoTz42ORWESIcZdIHzGefNBIFjQBW9AtgNHQMRmbZyQE7of~Xt-QSuC28GdUfMW-hoDe6~mzoX-eoLNIihboKf01IM8bHj8ounChVzvjtocgxYH5-JIhiCE7HZl6ehb7XP78bZ1iGf3gltc0bX9XZVP9k1t89FKozN2~uhybgcSQjzU-UZgZYA4hOjEstSP27QNOrYLt6EqZn6N4ZkIp8dglRsdr6h-sBjSonO-wYvxPUPHKtHy~d7GfjItAzOLiK~VuoCgmrerFmnBVIacYMguHa11AVHedWQmzcrEV0ZDLh9HxMyAytPK0YlFL1hy1OhkWmg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"},{"id":116560556,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560556/thumbnails/1.jpg","file_name":"4258.pdf","download_url":"https://www.academia.edu/attachments/116560556/download_file","bulk_download_file_name":"Ecological_Interferents_on_Cognitive_Eva.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560556/4258-libre.pdf?1720035849=\u0026response-content-disposition=attachment%3B+filename%3DEcological_Interferents_on_Cognitive_Eva.pdf\u0026Expires=1733182941\u0026Signature=As-ZHPSsYjDatwa~Dtrxjm-x3R-Jm2a9pFA87KoVtQqjiEVk8JJOno0pNidGg1esTkOiDpEv4BbPRXbo0exAb8~ATyjWhoNLWd4HWyNOQ4o7DIZnVDK703o2wKdxtGuG0Yjaoy55MsbWoZtX03TZZdmqrbQ-RYF71MKfAC9Xu8LO0NuAAmJZvnqbkVh~vjXTnsVf6CWAvGxZ317hdPHbNoW1KxrZpjlQk1Y8c5n4ErAedIgntbMWZ04QGQPqvK5F7uFczVhC7MejtczP63RnoyPdNuY9vbosw8aek8qWvBhyiFOpe1OUnjnDd9JE41XH597hBrGfwMzKQM-GCHQJkg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":261,"name":"Geography","url":"https://www.academia.edu/Documents/in/Geography"},{"id":4212,"name":"Cognition","url":"https://www.academia.edu/Documents/in/Cognition"},{"id":13298,"name":"Methylmercury","url":"https://www.academia.edu/Documents/in/Methylmercury"},{"id":1434261,"name":"Underdevelopment","url":"https://www.academia.edu/Documents/in/Underdevelopment"}],"urls":[{"id":43358890,"url":"https://revistas.ufrj.br/index.php/oa/article/download/5671/4258"}]}, dispatcherData: dispatcherData });

Whereas diffuse pollution occurs throughout the Piabanha river basin, the aim of this work was to evaluate the distribution of trace elements and persistent organic pollutants in its sediments over time and space, gathering information to assess the risks to the ecosystem and the population. And also to provide data to orient governmental institutions management of water resources in this region. The levels of organic pollutants highlight the influence of the historical use of pesticides in farming and industrial activities, mainly for Posse (203.36 ng/g dry weight) and Fagundes river (198.33 ng/g d.w) during the dry season and Moura Brazil (77.50 ng/g d.w) and Garagem (77.06 ng/g d.w) in the rainy season. In relation to available trace elements, the most contaminated locations were within and around Petrópolis center, possibly by industrial and domestic effluents, where Liceu (44-245 µg/g d.w) and Garagem (15-189 µg/g d.w) showed the highest concentrations of zinc. Furthermore, Liceu (5-58 µg/g d.w) also excelled in concentrations of lead. Cadmium was the element with major contribution to the contamination of the locations studied (Geoaccumulation index from 3 to 5 in all collected points), mainly because of its high mobility and the river flow. In addition, Poço do Ferreira river presented trace elements levels that exceeds the level 2 of the National Environment Council (CONAMA) classification. The authors highlight the need for a monitoring program on this region for the contaminants analyzed.","publication_date":{"day":null,"month":null,"year":2018,"errors":{}},"publication_name":"Orbital: The Electronic Journal of Chemistry","grobid_abstract_attachment_id":116560575},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753907/Current_State_of_Contamination_by_Persistent_Organic_Pollutants_and_Trace_Elements_on_Piabanha_River_Basin_Rio_de_Janeiro_Brazil","translated_internal_url":"","created_at":"2024-07-03T11:45:57.261-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560575,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560575/thumbnails/1.jpg","file_name":"6431feaf7a388b4b11e1759a228600cc9e93.pdf","download_url":"https://www.academia.edu/attachments/116560575/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Current_State_of_Contamination_by_Persis.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560575/6431feaf7a388b4b11e1759a228600cc9e93-libre.pdf?1720035822=\u0026response-content-disposition=attachment%3B+filename%3DCurrent_State_of_Contamination_by_Persis.pdf\u0026Expires=1733236830\u0026Signature=H5vAyBYQIJ1Edj2bo0RPE-QMRvJrCaenTANFtmeSAGaKpAhU7QC2goIbGJlYnT4iE-UxRYFDljwd~E5p-yCFsF4JQHrViuFByfOzW-fPnX6ROMCu6yMuhPc8pGCa1yvjG2bp4u0TUgVhnr5h~o-pKDqReZwwlFAMdV49xfbpWTbRCpHiEkNjLgclwYWdUYZnCAzvQ929pSLXk~NEkulFSDsWJu3JXliZfWJFhw8dyMAws~i4TDElCoVl61WdPocIsN0UOugYcNnw~e~kMFevTkemn71fWuzmc-a4jWFPzMxVSKpvYnc8a8CG6u99eBAqXqnhulKkiJh95mUq8CnrwQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Current_State_of_Contamination_by_Persistent_Organic_Pollutants_and_Trace_Elements_on_Piabanha_River_Basin_Rio_de_Janeiro_Brazil","translated_slug":"","page_count":10,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560575,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560575/thumbnails/1.jpg","file_name":"6431feaf7a388b4b11e1759a228600cc9e93.pdf","download_url":"https://www.academia.edu/attachments/116560575/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Current_State_of_Contamination_by_Persis.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560575/6431feaf7a388b4b11e1759a228600cc9e93-libre.pdf?1720035822=\u0026response-content-disposition=attachment%3B+filename%3DCurrent_State_of_Contamination_by_Persis.pdf\u0026Expires=1733236830\u0026Signature=H5vAyBYQIJ1Edj2bo0RPE-QMRvJrCaenTANFtmeSAGaKpAhU7QC2goIbGJlYnT4iE-UxRYFDljwd~E5p-yCFsF4JQHrViuFByfOzW-fPnX6ROMCu6yMuhPc8pGCa1yvjG2bp4u0TUgVhnr5h~o-pKDqReZwwlFAMdV49xfbpWTbRCpHiEkNjLgclwYWdUYZnCAzvQ929pSLXk~NEkulFSDsWJu3JXliZfWJFhw8dyMAws~i4TDElCoVl61WdPocIsN0UOugYcNnw~e~kMFevTkemn71fWuzmc-a4jWFPzMxVSKpvYnc8a8CG6u99eBAqXqnhulKkiJh95mUq8CnrwQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":402,"name":"Environmental Science","url":"https://www.academia.edu/Documents/in/Environmental_Science"},{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":198066,"name":"Contamination","url":"https://www.academia.edu/Documents/in/Contamination"},{"id":538342,"name":"Pollutant","url":"https://www.academia.edu/Documents/in/Pollutant"}],"urls":[]}, dispatcherData: dispatcherData });

DDT and its metabolites were detected in approximately 70.0% of the hair samples from all areas, and its concentrations ranged from 50.3 ng.g-1 to 141.8 ng.g-1 in Cubatão Center and Pilões and Água Fria, respectively. The highest p,p'-DDT concentration was detected in Pilões and Água Fria (134 ng.g-1) and, Cubatão Center (43.9 ng.g-1) exhibited the lowest concentration. There was not a clear association between the occurrence of evaluated diseases and DDT detection in hair. None of the locally produced groceries appeared to be risk factors for the presence of DDT in hair. However, DDT concentrations found in this study showed an increase of DDT available for human exposure. These results strengthen the evidence of current exposure routes between DDT and the population of the estuarine region; therefore, this issue deserves further investigation.","publication_date":{"day":null,"month":null,"year":2018,"errors":{}},"publication_name":"Orbital: The Electronic Journal of Chemistry","grobid_abstract_attachment_id":116560574},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753906/Determination_of_Environmental_Exposure_to_DDT_by_Human_Hair_Analysis_in_Santos_and_S%C3%A3o_Vicente_Estuary_S%C3%A3o_Paulo_Brazil","translated_internal_url":"","created_at":"2024-07-03T11:45:57.086-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560574,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560574/thumbnails/1.jpg","file_name":"pdf.pdf","download_url":"https://www.academia.edu/attachments/116560574/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Determination_of_Environmental_Exposure.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560574/pdf-libre.pdf?1720035812=\u0026response-content-disposition=attachment%3B+filename%3DDetermination_of_Environmental_Exposure.pdf\u0026Expires=1733236830\u0026Signature=E789Dh7M-R-3pasNeYeQBfiL71Obb~lw6J6GcNOuCA00V0K0-~axpleuYNh238kDBh0NZh-XK2Ma1pGIzR~udqMrEp6rQvCYeUEqTGwndiBKLuymCns9pALOanmZQwp-xalRFlZvY6~ESr2zkv6~HOFnwLpWnT59hgjsMOODMWch4FKiF3anWN1PoJoQDVqhaVKwStNLmpdZKDgy64lB3ZVuaVAvXdaQfsWUnF~s7HVq3IkxAPF4-d9s~44rHPXH5UW5Dleu2BXHtY89CPnwrQgwcSc6hUPurU6UOuFzx98Z8J6hVzPt0cVSEY6rflm-R~yELwmuMyBdRxE3FgYrGA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Determination_of_Environmental_Exposure_to_DDT_by_Human_Hair_Analysis_in_Santos_and_São_Vicente_Estuary_São_Paulo_Brazil","translated_slug":"","page_count":12,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560574,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560574/thumbnails/1.jpg","file_name":"pdf.pdf","download_url":"https://www.academia.edu/attachments/116560574/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Determination_of_Environmental_Exposure.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560574/pdf-libre.pdf?1720035812=\u0026response-content-disposition=attachment%3B+filename%3DDetermination_of_Environmental_Exposure.pdf\u0026Expires=1733236830\u0026Signature=E789Dh7M-R-3pasNeYeQBfiL71Obb~lw6J6GcNOuCA00V0K0-~axpleuYNh238kDBh0NZh-XK2Ma1pGIzR~udqMrEp6rQvCYeUEqTGwndiBKLuymCns9pALOanmZQwp-xalRFlZvY6~ESr2zkv6~HOFnwLpWnT59hgjsMOODMWch4FKiF3anWN1PoJoQDVqhaVKwStNLmpdZKDgy64lB3ZVuaVAvXdaQfsWUnF~s7HVq3IkxAPF4-d9s~44rHPXH5UW5Dleu2BXHtY89CPnwrQgwcSc6hUPurU6UOuFzx98Z8J6hVzPt0cVSEY6rflm-R~yELwmuMyBdRxE3FgYrGA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":379570,"name":"Estuary","url":"https://www.academia.edu/Documents/in/Estuary"}],"urls":[]}, dispatcherData: dispatcherData });

Federal do Mato Grosso do Sul","ai_title_tag":"Exposure to Organochlorine Pesticides and Methylmercury in Amazon Catfish","grobid_abstract":"The worldwide massive use of organochlorine pesticides (OCPs) and mercury (Hg) is taken as an environmental threat due to their high toxicity, potential for long-range transport, bioaccumulation and persistence. Both, OCPs and Hg, were widely used in the Brazilian Amazon region and deserve more attention in terms of environmental and public health. Focusing on expanding the knowledge about impacted areas and its consequences for local people, this study measured concentrations of OCPs and Hg in catfish (Ageneiosus brevifilis) samples. Moreover, a non-target analysis of organohalogen contaminants was carried out by means of full-scan screening. DDT and methylmercury showed the highest concentration values, ranging from 101 to 2061 µg kg-1 w.w. and 629 to 2009 µg kg-1 w.w., respectively. Pentachloroanisole was the only non-target organohalogenated compound identified and it was present in all samples. Estimated daily intake values did not exceed the safe reference limits proposed by the World Health Organization for OCPs, with the exception in some cases of heptachlor. On the other hand, the safe reference value of methylmercury was surpassed in all the fish samples. Results dismiss a recent input of OCPs due to greater contribution of pesticide metabolites, however, they point out a health risk hazard to riparian people. The concentrations of methylmercury and total dichlorodiphenyltrichloroethane, were up to one order of importance higher than other contaminants, which endorses that this region is still a hotspot for these contaminants.","publication_date":{"day":null,"month":null,"year":2018,"errors":{}},"publication_name":"Orbital: The Electronic Journal of Chemistry","grobid_abstract_attachment_id":116560577},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753905/Amazon_Riparian_People_s_Exposure_to_Legacy_Organochlorine_Pesticides_and_Methylmercury_from_Catfish_Ageneiosus_brevifilis_Intake","translated_internal_url":"","created_at":"2024-07-03T11:45:56.895-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560577,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560577/thumbnails/1.jpg","file_name":"518.pdf","download_url":"https://www.academia.edu/attachments/116560577/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Amazon_Riparian_People_s_Exposure_to_Leg.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560577/518-libre.pdf?1720035818=\u0026response-content-disposition=attachment%3B+filename%3DAmazon_Riparian_People_s_Exposure_to_Leg.pdf\u0026Expires=1733236830\u0026Signature=f5jwaStBkT2sc5ogve84A4NdZ-m5jADGnt6472G5JoyrBb5RvGQmX1J3kwA~gHQPBPdpWAiqAn3Sq-eAwnnVyiVsEt7mfY4pmbAy0Yues2OjIMz3hvnK48pyPxeraH4KfDR9QGrTU02rwCiQkZcZJiaP7cmltUFza9NOXHLa-kpwgceInhSvM4hLhEFE5lFh3JyplmPpka10fL2Hd2xd84t71nUPXjkpLZtiTJKKB5nDyAmGHbXSrUJ23eh1cK84w-9l4g92AJdO73FmPdCkd-dwb92fVGD-hvPzEJplCrUBkjf0-tbd2qc1A2foEQKPeY-JerBRbZh93jsykH~buQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Amazon_Riparian_People_s_Exposure_to_Legacy_Organochlorine_Pesticides_and_Methylmercury_from_Catfish_Ageneiosus_brevifilis_Intake","translated_slug":"","page_count":7,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560577,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560577/thumbnails/1.jpg","file_name":"518.pdf","download_url":"https://www.academia.edu/attachments/116560577/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Amazon_Riparian_People_s_Exposure_to_Leg.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560577/518-libre.pdf?1720035818=\u0026response-content-disposition=attachment%3B+filename%3DAmazon_Riparian_People_s_Exposure_to_Leg.pdf\u0026Expires=1733236830\u0026Signature=f5jwaStBkT2sc5ogve84A4NdZ-m5jADGnt6472G5JoyrBb5RvGQmX1J3kwA~gHQPBPdpWAiqAn3Sq-eAwnnVyiVsEt7mfY4pmbAy0Yues2OjIMz3hvnK48pyPxeraH4KfDR9QGrTU02rwCiQkZcZJiaP7cmltUFza9NOXHLa-kpwgceInhSvM4hLhEFE5lFh3JyplmPpka10fL2Hd2xd84t71nUPXjkpLZtiTJKKB5nDyAmGHbXSrUJ23eh1cK84w-9l4g92AJdO73FmPdCkd-dwb92fVGD-hvPzEJplCrUBkjf0-tbd2qc1A2foEQKPeY-JerBRbZh93jsykH~buQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":13298,"name":"Methylmercury","url":"https://www.academia.edu/Documents/in/Methylmercury"},{"id":65590,"name":"Pesticide","url":"https://www.academia.edu/Documents/in/Pesticide"},{"id":226114,"name":"Catfish","url":"https://www.academia.edu/Documents/in/Catfish"},{"id":373781,"name":"Amazon rainforest","url":"https://www.academia.edu/Documents/in/Amazon_rainforest"},{"id":3795346,"name":"Organochlorine pesticide","url":"https://www.academia.edu/Documents/in/Organochlorine_pesticide"}],"urls":[]}, dispatcherData: dispatcherData });

Due to long-range atmospheric transport, environmental persistence and toxicological potential of organochlorine pesticides (OCPs), similar characteristics of current-use pesticides (CUPs) and their massive use in Brazil, these contaminants have become a major concern for environmental and human life. Thus, this study aimed to evaluate subgroups or individual chemicals of OCPs and CUPs, which could have travelled over two Conservation Unit sites in the Rio de Janeiro state. The study was carried out for 24 months, (2013e2015), in Itatiaia National Park (INP) and in the Serra dos Orgãos National Park (SONP), at~2400 and~2200 meters above sea level, respectively. The study was based on atmospheric passive sampling (polyurethane foam disks). Target pesticides were detected by means of gas chromatography device coupled with mass spectrometry (GC-MS). Significantly higher concentrations were measured in SONP when compared to INP. However, in broad terms, the contamination profile was quite similar for both national parks: The highest concentrations of endosulfan (INP-1275 pg m À3 and SONP-3202 pg m À3) were followed by cypermethrin (INP-148 pg m À3 and SONP-881 pg m À3) and chlorpyrifos (INP-67 pg m À3 and SONP-270 pg m À3). In agreement with previous studies, the atmospheric concentrations of legacy OCPs showed background air levels. The decrease of endosulfan over the years was highlighted with a parallel increase of chlorpyrifos, suggesting a collateral effect of the national bias of permissive and massive use of agrochemicals. CUPs seemed to behave like pseudo-persistent pollutants (pseudo-POPs). This is the first report of atmospheric concentrations of pyrethroids in Brazilian mountain regions, and possibly the first to investigate them in the air in South America or in any mountain region in the world.","publication_date":{"day":null,"month":null,"year":2018,"errors":{}},"publication_name":"Environmental Pollution","grobid_abstract_attachment_id":116560576},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753904/Air_contamination_by_legacy_and_current_use_pesticides_in_Brazilian_mountains_An_overview_of_national_regulations_by_monitoring_pollutant_presence_in_pristine_areas","translated_internal_url":"","created_at":"2024-07-03T11:45:56.640-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560576,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560576/thumbnails/1.jpg","file_name":"Guida_et_al.2c_2018_-ENPO.pdf","download_url":"https://www.academia.edu/attachments/116560576/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Air_contamination_by_legacy_and_current.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560576/Guida_et_al.2c_2018_-ENPO-libre.pdf?1720035817=\u0026response-content-disposition=attachment%3B+filename%3DAir_contamination_by_legacy_and_current.pdf\u0026Expires=1733236830\u0026Signature=gfRGifMGo6HstPZOGeSDjEwGg9BLSWgxdNFeCBYTtGzJd9WMlDJn3V23vj2-nl6U5i4DlHgYafhI-eJj9iVuEYAsUvZVDufF5E29yDwNvZZD9cImAw7rJVGUk20Y3T0uv88dipyDFomwXMuHBzLAF02Q2X82KcY53WBAgJKQ~I9pc1LtNMbUPVNqpQ2Oppso7W3QDAQ~VcRm63DDcnJKurY~DVZxihQePNm0EiV7kdmTLixs1KINVJLBTKxHGj06Q7yEPz~pjM2VBjK1naRgvge-5s~Zl1GDzXZgyvKk4WU9CR-8RbqpZ2aVbBwgNsMfcCFyWcnV3SePmFrgbylGnQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Air_contamination_by_legacy_and_current_use_pesticides_in_Brazilian_mountains_An_overview_of_national_regulations_by_monitoring_pollutant_presence_in_pristine_areas","translated_slug":"","page_count":12,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560576,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560576/thumbnails/1.jpg","file_name":"Guida_et_al.2c_2018_-ENPO.pdf","download_url":"https://www.academia.edu/attachments/116560576/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Air_contamination_by_legacy_and_current.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560576/Guida_et_al.2c_2018_-ENPO-libre.pdf?1720035817=\u0026response-content-disposition=attachment%3B+filename%3DAir_contamination_by_legacy_and_current.pdf\u0026Expires=1733236830\u0026Signature=gfRGifMGo6HstPZOGeSDjEwGg9BLSWgxdNFeCBYTtGzJd9WMlDJn3V23vj2-nl6U5i4DlHgYafhI-eJj9iVuEYAsUvZVDufF5E29yDwNvZZD9cImAw7rJVGUk20Y3T0uv88dipyDFomwXMuHBzLAF02Q2X82KcY53WBAgJKQ~I9pc1LtNMbUPVNqpQ2Oppso7W3QDAQ~VcRm63DDcnJKurY~DVZxihQePNm0EiV7kdmTLixs1KINVJLBTKxHGj06Q7yEPz~pjM2VBjK1naRgvge-5s~Zl1GDzXZgyvKk4WU9CR-8RbqpZ2aVbBwgNsMfcCFyWcnV3SePmFrgbylGnQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":402,"name":"Environmental Science","url":"https://www.academia.edu/Documents/in/Environmental_Science"},{"id":15836,"name":"Environmental Chemistry","url":"https://www.academia.edu/Documents/in/Environmental_Chemistry"},{"id":25445,"name":"Environmental Pollution","url":"https://www.academia.edu/Documents/in/Environmental_Pollution"},{"id":26327,"name":"Medicine","url":"https://www.academia.edu/Documents/in/Medicine"},{"id":28235,"name":"Multidisciplinary","url":"https://www.academia.edu/Documents/in/Multidisciplinary"},{"id":65590,"name":"Pesticide","url":"https://www.academia.edu/Documents/in/Pesticide"},{"id":167983,"name":"Endosulfan","url":"https://www.academia.edu/Documents/in/Endosulfan"},{"id":198066,"name":"Contamination","url":"https://www.academia.edu/Documents/in/Contamination"},{"id":284869,"name":"National Park","url":"https://www.academia.edu/Documents/in/National_Park"},{"id":764674,"name":"Chlorpyrifos","url":"https://www.academia.edu/Documents/in/Chlorpyrifos"}],"urls":[{"id":43358888,"url":"https://api.elsevier.com/content/article/PII:S0269749118314441?httpAccept=text/xml"}]}, dispatcherData: dispatcherData });

However, little is known regarding aeration effects in suspended particulate aggregates. Therefore, this study aimed to investigate the effects of aeration on the suspended matter from a Tropical and Eutrophic estuarine environment. Anoxic water with 60 g/L of suspended particulate matter (SPM) was collected from Guanabara Bay, Rio de Janeiro, Brazil, transferred to experimental boxes and aerated for 61 days. SPM aggregates monitoring included abiotic variables measurements and, determination of total organic matter (TOM), biopolymers composition, bacterial activity, trace metals, and polycyclic aromatic hydrocarbons (PAHs) concentrations. The aeration enhanced dissolved oxygen (DO) concentration and the redox potential (Eh). However, from days 0 to 61 the predominant bacterial activities were denitrification and fermentation. Electron transport system activity increased after day 10, and aerobic activity was detected after day 19. In summary, aeration increased aerobic bacterial activity, lipids (LIP) and trace metal concentrations, although diminished protein/carbohydrate ratio and PAH concentration. Trace metals concentration (Ni, Pb, Cu, Cr, Mn, and Fe) were the highest on day 19 when the pH was 5.9. Copper presented toxic values (Cu \u003e 20.0 μg/g). The pH showed a strong negative correlation with Eh (r = − 0.94; p \u003c 0.001). Acidic environment (pH ≤ 5.9) in marine ecosystems with high loads of toxic trace metals is unsafe for biota. Therefore, managers must be aware of the environmental and biological risks of introducing the aeration technique into a eutrophic marine environment.","publication_date":{"day":null,"month":null,"year":2019,"errors":{}},"publication_name":"Journal of Environmental Sciences","grobid_abstract_attachment_id":116560573},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753903/Effects_of_aeration_on_the_suspended_matter_from_a_tropical_and_eutrophic_estuary","translated_internal_url":"","created_at":"2024-07-03T11:45:56.386-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560573,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560573/thumbnails/1.jpg","file_name":"create_pdf.pdf","download_url":"https://www.academia.edu/attachments/116560573/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Effects_of_aeration_on_the_suspended_mat.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560573/create_pdf-libre.pdf?1720035827=\u0026response-content-disposition=attachment%3B+filename%3DEffects_of_aeration_on_the_suspended_mat.pdf\u0026Expires=1733236830\u0026Signature=HcfwKw7rxlMJJ6vUXULiBaq5qxKDCmjH~IyeEOVILBpRQ-Pn4bRzyShPOlEFcdlU8~PdqUl1lIVbuDvwnxQNdKRD6wmSVqQZH-l2VamG5xB0vrSQNZfmnAhQ9fsm0tStzMB4iXZPRbIjBwZqI0eKbOi9szJZ~xa-e2rX-GihNhU1LFcQ8rDtohFlp98E6e7szc8fBer-3PlV8-QyyD35eQq~46uGJmJmVHx47P~ZTHT~yAM4zLXROG-LYf0MnZKciAxrOaI8F5crGZrTFJqdf4ihXHwDtj6K63OFNJqI2zbbC3loURjghBT3sLoXphNwbJLRRXvfxkWTkQ3NqP6kdg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Effects_of_aeration_on_the_suspended_matter_from_a_tropical_and_eutrophic_estuary","translated_slug":"","page_count":12,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560573,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560573/thumbnails/1.jpg","file_name":"create_pdf.pdf","download_url":"https://www.academia.edu/attachments/116560573/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Effects_of_aeration_on_the_suspended_mat.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560573/create_pdf-libre.pdf?1720035827=\u0026response-content-disposition=attachment%3B+filename%3DEffects_of_aeration_on_the_suspended_mat.pdf\u0026Expires=1733236830\u0026Signature=HcfwKw7rxlMJJ6vUXULiBaq5qxKDCmjH~IyeEOVILBpRQ-Pn4bRzyShPOlEFcdlU8~PdqUl1lIVbuDvwnxQNdKRD6wmSVqQZH-l2VamG5xB0vrSQNZfmnAhQ9fsm0tStzMB4iXZPRbIjBwZqI0eKbOi9szJZ~xa-e2rX-GihNhU1LFcQ8rDtohFlp98E6e7szc8fBer-3PlV8-QyyD35eQq~46uGJmJmVHx47P~ZTHT~yAM4zLXROG-LYf0MnZKciAxrOaI8F5crGZrTFJqdf4ihXHwDtj6K63OFNJqI2zbbC3loURjghBT3sLoXphNwbJLRRXvfxkWTkQ3NqP6kdg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":400,"name":"Earth Sciences","url":"https://www.academia.edu/Documents/in/Earth_Sciences"},{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":15836,"name":"Environmental Chemistry","url":"https://www.academia.edu/Documents/in/Environmental_Chemistry"},{"id":26181,"name":"Eutrophication","url":"https://www.academia.edu/Documents/in/Eutrophication"},{"id":26327,"name":"Medicine","url":"https://www.academia.edu/Documents/in/Medicine"},{"id":58054,"name":"Environmental Sciences","url":"https://www.academia.edu/Documents/in/Environmental_Sciences"},{"id":172487,"name":"Airborne Particulates","url":"https://www.academia.edu/Documents/in/Airborne_Particulates"},{"id":260118,"name":"CHEMICAL SCIENCES","url":"https://www.academia.edu/Documents/in/CHEMICAL_SCIENCES"},{"id":379570,"name":"Estuary","url":"https://www.academia.edu/Documents/in/Estuary"},{"id":803011,"name":"Aeration","url":"https://www.academia.edu/Documents/in/Aeration"},{"id":970387,"name":"Organic Matter","url":"https://www.academia.edu/Documents/in/Organic_Matter"}],"urls":[{"id":43358887,"url":"https://api.elsevier.com/content/article/PII:S1001074219304899?httpAccept=text/xml"}]}, dispatcherData: dispatcherData });

Low density polyethylene passive samplers were deployed in upland surface waters and the overlying atmosphere in subtropical and tropical mountain regions in south and southeast Brazil, respectively, to determine the concentrations, transport and sources of freely dissolved and gaseous polycyclic aromatic hydrocarbons (PAHs) along altitudinal gradients. Gaseous PAH concentrations (0.70-90 ng.m-3) were dominated by phenanthrene and fluorene, though methylnaphthalenes displayed high concentrations at upland sites. Fluoranthene and chrysene were the most frequently detected PAHs in shallow waters (10-110 pg.L-1). Individual PAHs indicated a wood/grass combustion origin at both national parks due to current and historical man-made fires, with a minor petrogenic fingerprint, probably due to the proximity of highway traffic and touristic activities. A slightly increasing trend of 2-3 ring PAHs was observed along tropical elevation transect which may reflect longrange atmospheric transport of more volatile PAHs over tropical elevated altitudes. However, local PAH emission sources probably explain the opposite trend detected at subtropical elevation transect.","publication_date":{"day":null,"month":null,"year":2018,"errors":{}},"publication_name":"Atmospheric Pollution Research","grobid_abstract_attachment_id":116560572},"translated_abstract":null,"internal_url":"https://www.academia.edu/121753902/Passive_sampler_derived_concentrations_of_PAHs_in_air_and_water_along_Brazilian_mountain_transects","translated_internal_url":"","created_at":"2024-07-03T11:45:56.144-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116560572,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560572/thumbnails/1.jpg","file_name":"1-s2.0-S1309104218303878-main.pdf","download_url":"https://www.academia.edu/attachments/116560572/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Passive_sampler_derived_concentrations_o.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560572/1-s2.0-S1309104218303878-main-libre.pdf?1720035822=\u0026response-content-disposition=attachment%3B+filename%3DPassive_sampler_derived_concentrations_o.pdf\u0026Expires=1733236830\u0026Signature=PxaKqlhM~lQczHkTWz2j3XDYtXLgOPmxZbgaNEYS57TFM2h530P0dZ6eZd1CbH5h81CmLS72LnuuyiqXn8FllDJ9kPzIeSwTZJJNGi5fiOWyHvq0fKZaE-qEitn7GikUeMr4e9Ht0aPxNTex9vgyWD9L4qxuOd29ifAoLgOclr37U6yox-LkR2N272yrtK25050MskqIc6NlPmTuFlFu2w7OYmSeANihtAXI0zGCU0Q-TDOAu2rFEsbqaMXi6lLc32kCLdc7W9E-bFhfH8LsbrZmYsbvA9KsyIGzaQqf8HiCfFOaDMVXKDH2afHm057ZhZJLiHnvy9UzabrVk~OPdw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Passive_sampler_derived_concentrations_of_PAHs_in_air_and_water_along_Brazilian_mountain_transects","translated_slug":"","page_count":34,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":116560572,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116560572/thumbnails/1.jpg","file_name":"1-s2.0-S1309104218303878-main.pdf","download_url":"https://www.academia.edu/attachments/116560572/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Passive_sampler_derived_concentrations_o.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116560572/1-s2.0-S1309104218303878-main-libre.pdf?1720035822=\u0026response-content-disposition=attachment%3B+filename%3DPassive_sampler_derived_concentrations_o.pdf\u0026Expires=1733236830\u0026Signature=PxaKqlhM~lQczHkTWz2j3XDYtXLgOPmxZbgaNEYS57TFM2h530P0dZ6eZd1CbH5h81CmLS72LnuuyiqXn8FllDJ9kPzIeSwTZJJNGi5fiOWyHvq0fKZaE-qEitn7GikUeMr4e9Ht0aPxNTex9vgyWD9L4qxuOd29ifAoLgOclr37U6yox-LkR2N272yrtK25050MskqIc6NlPmTuFlFu2w7OYmSeANihtAXI0zGCU0Q-TDOAu2rFEsbqaMXi6lLc32kCLdc7W9E-bFhfH8LsbrZmYsbvA9KsyIGzaQqf8HiCfFOaDMVXKDH2afHm057ZhZJLiHnvy9UzabrVk~OPdw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":402,"name":"Environmental Science","url":"https://www.academia.edu/Documents/in/Environmental_Science"},{"id":15836,"name":"Environmental Chemistry","url":"https://www.academia.edu/Documents/in/Environmental_Chemistry"},{"id":162644,"name":"Transect","url":"https://www.academia.edu/Documents/in/Transect"},{"id":216113,"name":"Atmospheric pollution","url":"https://www.academia.edu/Documents/in/Atmospheric_pollution"},{"id":772819,"name":"Phenanthrene","url":"https://www.academia.edu/Documents/in/Phenanthrene"},{"id":976496,"name":"Fluoranthene","url":"https://www.academia.edu/Documents/in/Fluoranthene"},{"id":1872418,"name":"Subtropics","url":"https://www.academia.edu/Documents/in/Subtropics"}],"urls":[{"id":43358886,"url":"https://api.elsevier.com/content/article/PII:S1309104218303878?httpAccept=text/xml"}]}, dispatcherData: dispatcherData });

Air, soil, and atmospheric deposition process in the Pearl River Delta of South China were investigated, and the average SCCP and MCCP concentrations were 5.2 μg/sampler (17.69 ng/m 3) and 4.1 μg/sampler for passive air samples, 18.3 and 59.3 ng/g for soil samples, and 5.0 and 5.3 μg/(m 2 d) for deposition samples, respectively. Influenced by primary sources and the properties of chlorinated paraffins (CPs), a gradient trend of concentrations and a fractionation of composition from more to less industrialized areas were discovered. Intense seasonal variations with high levels in summer air and winter deposition samples indicated that the air and deposition CP levels were controlled mainly by the vapor and particle phase, respectively. Complex environmental processes like volatilization and fractionation resulted in different CP profiles in different environment matrixes and sampling locations, with C 10−11 Cl 6−7 and C 14 Cl 6−7 , C 10−12 Cl 6−7 and C 14 Cl 6−8 , and C 11−12 Cl 6−8 and C 14 Cl 7−8 dominating in air, soil, and atmospheric deposition, respectively. Shorter-chain and less chlorinated congeners were enriched in air in the less industrialized areas, while longer-chain and higher chlorinated congeners were concentrated in soil in the more industrialized areas.

Federal do Mato Grosso do Sul","grobid_abstract":"Considered the worst environmental disaster in Brazilian history, the collapse of Samarco dam directly affected the Doce river. Inhabitants living along the river who relied mainly on Doce river's water supply for agriculture and human consumption faced risk from the mining residue exposure. This study aimed to investigate the disaster's impact on small family farmers living in Minas Gerais and Espírito Santo States by water elemental quantification and evaluate the potential pathways of contamination by survey. In July 2016, 48 water points-including well, river and public distributed water-of 3 cities (Belo Oriente, Governador Valadares and Colatina) were sampled for determination of As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Sn and Zn elements. Ninety-eight percent of the inhabitants interviewed related Doce river water usage before the tragedy for diversified purposes, while only thirty-six per cent used it after the disaster, mainly for irrigation. Fe and Mn presented concentrations above the Brazilian legislation for drinking water and irrigation in all locations, but not in all samples. Pb concentration was above the drinking water legislation in one location. All the other elements concentrations were within safe limits. Colatina, the farthest city from the dam, presented the highest values, followed by Governador Valadares and Belo Oriente.","publication_date":{"day":null,"month":null,"year":2018,"errors":{}},"publication_name":"Orbital: The Electronic Journal of Chemistry","grobid_abstract_attachment_id":114063354},"translated_abstract":null,"internal_url":"https://www.academia.edu/118435712/Metals_and_Arsenic_in_Water_Supply_for_Riverine_Communities_Affected_by_the_Largest_Environmental_Disaster_in_Brazil_The_Dam_Collapse_on_Doce_River","translated_internal_url":"","created_at":"2024-05-02T07:11:01.613-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":33141254,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":114063354,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/114063354/thumbnails/1.jpg","file_name":"eaa404a3f20b2ddf97d8249dd9ee5ad19650.pdf","download_url":"https://www.academia.edu/attachments/114063354/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Metals_and_Arsenic_in_Water_Supply_for_R.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/114063354/eaa404a3f20b2ddf97d8249dd9ee5ad19650-libre.pdf?1714662827=\u0026response-content-disposition=attachment%3B+filename%3DMetals_and_Arsenic_in_Water_Supply_for_R.pdf\u0026Expires=1733236831\u0026Signature=M5F0mZk9RYoHCY5~z~Jeg-efpsMz~K62vBiQyIyN-NoCjPFoelo4SVAcN~XJy1GlO7LJP~pj~Sf81C22LDgfWrPCpv9ytdEj00otSuR2tC75ckIe5MnSqwew1nphw3TExgzBq3vdU81U0BA7A5I-xatmIWt-n75d8zTB6bdEe4rpK~Rmvnihc7xxTusUaVqmgc0s2L8eo-FZ2BZyPoPzi~YgqwNXEQ72IN1-d1QMXZ5UaDWDJpjyEG-GJYpxFWcNgSgB1gqdZhrVZAX~NTEve1yVObedIatG0xu211qfQV77pmMcJrJMgZmKGJDSSa60J~AzBhJ47oF0Jc5yyr63cQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Metals_and_Arsenic_in_Water_Supply_for_Riverine_Communities_Affected_by_the_Largest_Environmental_Disaster_in_Brazil_The_Dam_Collapse_on_Doce_River","translated_slug":"","page_count":9,"language":"en","content_type":"Work","owner":{"id":33141254,"first_name":"Joao","middle_initials":null,"last_name":"Torres","page_name":"JoaoTorres","domain_name":"ufrj","created_at":"2015-07-17T09:07:11.134-07:00","display_name":"Joao Torres","url":"https://ufrj.academia.edu/JoaoTorres"},"attachments":[{"id":114063354,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/114063354/thumbnails/1.jpg","file_name":"eaa404a3f20b2ddf97d8249dd9ee5ad19650.pdf","download_url":"https://www.academia.edu/attachments/114063354/download_file?st=MTczMzI1NDcwMCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Metals_and_Arsenic_in_Water_Supply_for_R.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/114063354/eaa404a3f20b2ddf97d8249dd9ee5ad19650-libre.pdf?1714662827=\u0026response-content-disposition=attachment%3B+filename%3DMetals_and_Arsenic_in_Water_Supply_for_R.pdf\u0026Expires=1733236831\u0026Signature=M5F0mZk9RYoHCY5~z~Jeg-efpsMz~K62vBiQyIyN-NoCjPFoelo4SVAcN~XJy1GlO7LJP~pj~Sf81C22LDgfWrPCpv9ytdEj00otSuR2tC75ckIe5MnSqwew1nphw3TExgzBq3vdU81U0BA7A5I-xatmIWt-n75d8zTB6bdEe4rpK~Rmvnihc7xxTusUaVqmgc0s2L8eo-FZ2BZyPoPzi~YgqwNXEQ72IN1-d1QMXZ5UaDWDJpjyEG-GJYpxFWcNgSgB1gqdZhrVZAX~NTEve1yVObedIatG0xu211qfQV77pmMcJrJMgZmKGJDSSa60J~AzBhJ47oF0Jc5yyr63cQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":6227,"name":"Arsenic","url":"https://www.academia.edu/Documents/in/Arsenic"},{"id":64055,"name":"Water Supply","url":"https://www.academia.edu/Documents/in/Water_Supply"},{"id":156376,"name":"Water resource management","url":"https://www.academia.edu/Documents/in/Water_resource_management"},{"id":853578,"name":"Environmental Disaster","url":"https://www.academia.edu/Documents/in/Environmental_Disaster"}],"urls":[]}, dispatcherData: dispatcherData });

It presents a quite intense fishing activity and there is no known goldmining activity in its watershed. Fish and human hair were analyzed with a new extraction technique and measured by GC-ECD. Analytical quality was checked through intercomparisons between two laboratories with local samples and certified standards from IAEA. Methylmercury in hair ranged from 2.0 to 21.6 g • g ؊1 with a mean of 8.76$ $5.20 g • g ؊1 (N ‫؍‬ 20), while the methylmercury percentages were above 90. Fish presented methylmercury levels ranging from 0.03 to 0.9 g • g ؊1 wet wt with a mean of 0.24$ $0.18 g • g ؊1 wet wt (N ‫؍‬ 32), which is below the limit established for food by Brazilian legislation (0.5 g • g ؊1 wet wt) and methylmercury mean percentages were above 95%. The total mean daily methylmercury intake ranged from 11 to 55 g for 70% of the sampled population from the village based on a daily consumption of about 110 g of fish with methylmercury concentrations in the range of 0.1 to 0.5 g • g ؊1.
