Penguins are endemic species of Antarctica situated at the top of food web and are useful sentinels of pollution. To improve data of trace metal contamination in the Antarctic Peninsula region, concentrations of Cd, Pb, As, Cu and Zn in fresh excrement of penguins were determined by atomic absorption. Samples were collected in several locations during the 2011/2012 austral summer: eight sites (O'Higgins Station, Yankee Harbour, Mikkelsen Harbor, Danco Island, Gonzalez Videla Base, Yelcho Station and Brown Station) from gentoo penguin (Pygoscelis papua) colonies and four locations (Hydrurga Rocks, Cape Shirreff, Narebski Point and Kopaitic Island) from chinstrap penguin (Pygoscelis antarctica) colonies. Data showed that gentoo penguin colonies had higher levels of metals (lg g-1 dw) like Pb, Cu and Zn at locations such as O'Higgins (2.89 for Pb, 199.95 for Cu and 379.99 for Zn) and Gonzalez Videla (2.74 for Pb and 222.51 for Cu). Levels of Cd in excreta of chinstrap penguins were higher at Narebski Point (3.13 lg g-1). The levels of Pb, As, Cd, Cu and Zn were similar or even higher to those reported in excreta of the same species by previous studies at Antarctica. Data suggest that metals ingested by these two penguin species feeding in the sea end up in terrestrial ecosystems.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Concentration of trace metals in excrements of two species of penguins from different locations of the Antarctic Peninsula","attachmentId":68362127,"attachmentType":"pdf","work_url":"https://www.academia.edu/50337194/Concentration_of_trace_metals_in_excrements_of_two_species_of_penguins_from_different_locations_of_the_Antarctic_Peninsula","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/50337194/Concentration_of_trace_metals_in_excrements_of_two_species_of_penguins_from_different_locations_of_the_Antarctic_Peninsula"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="1" data-entity-id="81289891" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/81289891/Trace_metal_concentrations_and_body_condition_in_adult_Ad%C3%A9lie_penguins_Pygoscelis_adeliae_from_the_western_Antarctic_Peninsula">Trace metal concentrations and body condition in adult Adélie penguins (Pygoscelis adeliae) from the western Antarctic Peninsula</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="116690426" href="https://independent.academia.edu/RicardoSantelli">Ricardo Santelli</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Latin American Journal of Aquatic Research, 2020</p><p class="ds-related-work--abstract ds2-5-body-sm">Adélie penguins (Pygoscelis adeliae) are seabirds that live exclusively in Antarctica, one of the planet&#39;s last pristine areas. However, this remote region is experiencing a continuing expansion of human activities that may affect Antarctic fauna. Trace metals constitute a menace to seabirds because they can adversely affect their health. There is a lack of studies relating to metals&#39; levels in feathers with morphological parameters of seabirds. Trace metal levels were measured in Adélie penguin feathers and their body condition through the relative condition factor (ReCF) in adult individuals from two South Shetland Islands locations and two from Graham Land. Consequently, we determined the levels of some metals in feathers to see any relationship with morphological parameters linked to the bird&#39;s health.

Samples were collected during the 2002/2003 austral summer season campaign around Jubany Station (Argentine scientific station), Potter Cove, King George Island. Solutions of organs were prepared by acid-assisted microwave (MW) digestion by employing HNO 3 and H 2 0 2 . Instrumental techniques selected to analyze the different tissues were inductively coupled plasma optical emission spectroscopy (ICP OES) and inductively coupled plasma mass spectrometry (ICP-MS). A wide range of elements retention capacity among the different organs was observed and the ranges ascertained are as follows (in Ag g À 1 ): As, 0.5 (liver) -0.8 (muscle); Cd, < 0.07 (muscle) -3.4 (kidney); Co, 0.07 (liver) -0.7 (muscle); Cu, 0.6 (muscle) -18 (liver); Hg, 0.2 (kidney) -2.7 (liver); Mn, 1.5 (muscle) -10 (liver); Pb, 0.1 (muscle) -2.0 (liver); Se, 3.0 (muscle) -8.4 (liver). The observed trend in metal accumulation in the three organs of chick penguins was in the order Cu > Mn > Se > > As > Co > Pb > > Cd > Hg. Levels of metals and metalloids were, in general terms, higher in liver that is a specific target organ for metal accumulation.

Penguin chicks can reflect this potential impact in the rookeries during the breeding season. They also can reflect biomagnification phenomena since they are on the top of the Antarctic food chain. The concentrations of Al, Cr, Mn, Fe, Ni, Cu, Zn, As, Se, Cd and Pb were measured by ICP-MS in samples of liver, kidney, muscle, bone, feather and stomach content of gentoo, chinstrap and Adélie penguin chicks (n = 15 individuals) collected opportunistically in the Islands of King George and Deception (South Shetland Islands, Antarctica).

However, the northern region of the Antarctic Peninsula, is close to South America and experiences the greatest anthropogenic pressure in Antarctica. Here, we investigated, in two Antarctic Peninsula islands, intra and interspecific factors that influence the concentrations of 17 trace elements (TEs) in blood and feathers of three penguin species breeding sympatrically in relation to their trophic ecology assessed via a stable isotopic approach (C, N and S). Geographical location, foraging zone (d 13 C and d 34 S) and diet influences the interspecific difference, and sex and maturity stage diet influence the intraspecific difference of Pygoscelis penguins. Penguins from Livingston showed higher values (mean, ng. g À1 , dry weight-dw) of Zn (103), Mn (0.3), and Fe (95) than those from King George Island (Zn: 80, Mn: 1.9, and Fe: 11). Gender-related differences were observed, as males showed significantly higher values (mean, ng. g À1 , dw) of Rb (3.4) and d 15 N in blood of gentoo, and Ca (1344) in Ad elie feathers. Chicks of gentoo and Ad elie presented higher Zn, Mg, Ca, and Sr and lower 13 C values in blood than adults. The highest concentrations (mean, ng. g À1 , dw) of Cd (0.2) and Cu (26), and the lowest d 15 N values were found in chinstrap. Geographical, intraspecific (i.e., ontogenetic and gender-related) and interspecific differences in feeding seemed to have influenced TE and stable isotope values in these animals. The TE bioaccumulation by penguins may have also been influenced by natural enrichment in environmental levels of these elements, which seems to be the case for Fe, Zn, and Mn. However, the high level of some of the TEs (Mn, Cd, and Cr) may reflect the increase of local and global human activities.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Factors that influence trace element levels in blood and feathers of Pygoscelis penguins from South Shetland Islands, Antarctica","attachmentId":108663140,"attachmentType":"pdf","work_url":"https://www.academia.edu/111030119/Factors_that_influence_trace_element_levels_in_blood_and_feathers_of_Pygoscelis_penguins_from_South_Shetland_Islands_Antarctica","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/111030119/Factors_that_influence_trace_element_levels_in_blood_and_feathers_of_Pygoscelis_penguins_from_South_Shetland_Islands_Antarctica"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="7" data-entity-id="29578842" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/29578842/Biogenic_and_toxic_elements_in_feathers_eggs_and_excreta_of_Gentoo_penguin_Pygoscelis_papua_ellsworthii_in_the_Antarctic">Biogenic and toxic elements in feathers, eggs, and excreta of Gentoo penguin (Pygoscelis papua ellsworthii) in the Antarctic</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="16309482" href="https://independent.academia.edu/RoumianaMetcheva">Roumiana Metcheva</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Environmental Monitoring and Assessment, 2011</p><p class="ds-related-work--abstract ds2-5-body-sm">Feathers, eggs, and excreta of Gentoo penguin (Pygoscelis papua ellsworthii), adults, from Livingston Island (South Shetlands), chosen as bioindicators, were used to test the quality of the Antarctic environment.

For the first time data about the element contents in Gentoo eggs is provided. Two hypotheses were tested: (1) there are differences in the metal levels among eggs and feathers; and (2) the element concentrations are highest in the excreta. The hypotheses were confirmed at 0.01-0.05 confidence levels. The concentrations of almost all trace elements were significantly higher eas.

Se determinaron las concentraciones (peso seco) de arsénico (As), cadmio (Cd), mercurio (Hg) y plomo (Pb) y porfirinas (copro-, uro-y proto-) en heces de colonias de pingüinos Papua (Pygoscelis papua), colectadas en dos lugares de la península Antártica (O'Higgins y Videla). Se encontraron mayores (P < 0,05) niveles de Hg (7,55 ± 1,28 μg g-1) en las heces de colonias de pingüinos en O'Higgins, mientras que las colonias de pingüinos en Videla exhibieron mayores concentraciones de Cd (1,68 ± 0,71 μg g-1). Los pingüinos Papua de O'Higgins mostraron mayores (P < 0,05) niveles de copro-(1,81 ± 0,61 nmol g-1), uro-(1,74 ± 0,72 nmol g-1) y protoporfirinas (1,24 ± 0,46 nmol g-1), en directa relación con los mayores niveles de Hg y Pb medidos. Esto podría implicar que algunas colonias de pingüinos Papua de la península Antártica están propensas a desarrollar algunos efectos bioquímicos asociados a contaminación por metales traza. Estos resultados preliminares levantan inquietantes interrogantes acerca de la contaminación de origen antropogénico que estaría afectando áreas tan remotas como la Antártica.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"A preliminary study of trace metals and porphyrins in excreta of Gentoo penguins (Pygoscelis papua) at two locations of the Antarctic Peninsula","attachmentId":78163831,"attachmentType":"pdf","work_url":"https://www.academia.edu/67293470/A_preliminary_study_of_trace_metals_and_porphyrins_in_excreta_of_Gentoo_penguins_Pygoscelis_papua_at_two_locations_of_the_Antarctic_Peninsula","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/67293470/A_preliminary_study_of_trace_metals_and_porphyrins_in_excreta_of_Gentoo_penguins_Pygoscelis_papua_at_two_locations_of_the_Antarctic_Peninsula"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--sticky-ctas","attachmentId":47176638,"attachmentType":"pdf","workUrl":null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--sticky-ctas","attachmentId":47176638,"attachmentType":"pdf","workUrl":null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_47176638" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
