I worked at Kathmandu University for a decade (2008-2018). I was awarded (in 2009) and worked as ‘International Young Scientist’ at the Institute of Tibetan Plateau Research, Chinese Academy of Sciences. I involved as a post-doc researcher at Laboratory of Green Chemistry, Lappeenranta University of Technology, Finland in 2013. Recently, I was one of the PIFI Fellows at State Key Laboratory of Cryospheric Sciences, Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences in Lanzhou.<br /><br />My research mainly focuses on aquatic pollution (heavy metals and persistent organic pollutants), fisheries and ecotoxicology. Mercury pollution is one of the main focuses of my research at present.<br /><b>Address: </b>Department of Environmental Science and Engineering <br />Kathmandu University <br />Nepal<br /><div class="js-profile-less-about u-linkUnstyled u-tcGrayDarker u-textDecorationUnderline u-displayNone">less</div></div></div><div class="suggested-academics-container"><div class="suggested-academics--header"><p class="ds2-5-body-md-bold">Related Authors</p></div><ul class="suggested-user-card-list"><div class="suggested-user-card"><div class="suggested-user-card__avatar social-profile-avatar-container"><a href="https://kuleuven.academia.edu/NoelBSalazar"><img class="profile-avatar u-positionAbsolute" alt="Noel B.

Lakes were surveyed based on line transects using Echosounder (depth measuring gauge) and GPS to collect the data for bathymetry. Water samples were collected from 43 sites of nine lakes, considering the land use patterns, anthropogenic activities, inlets, and outlets. Twenty physico-chemical parameters were analyzed to know the water characteristics and pollution level. The bathymetry map showed that Jingale is the deepest lake (44 m), followed by Batula (15 m) and Mathillo Dhaune (9.5 m). There was no significant spatial variability in the concentration of physicochemical parameters among the sampling sites. The mean concentrations of cations and anions were in the order of Ca&gt; Mg&gt; Na&gt; K, and HCO3&gt; Cl&gt; SO4&gt; PO4&gt; NO3, respectively.

The highest total Hg concentration was found in X. cancila with an average of 800.42(±279.36) µg/kg exceeding the international marketing limit (500 mg/kg), a carnivorous species. However, except for some individuals of N. nandus, total Hg concentrations in other fish species in the present study were significantly lower than that limit. The fish community had at least two trophic levels (Δ15N &gt; 5.6), C. punctatus with the highest and M. vittatus the lowest signatures of δ15N, which was also supported by the stomach content analysis.

In this chapter, an overview of the water chemistry and the geochemical mechanisms that govern the characteristics of major ions and trace elements in rivers of the Third Pole are presented. In general, most rivers of the Third Pole have an alkaline water environment with an average pH of 8.7. As a result of intensive rock weathering within the catchments, the averaged total dissolved solids (~380 mg L−1) in the rivers of the Third Pole are much higher than the global median level. It was found that the dissolved contents in rivers of the Third Pole are dominated by Ca2+, Mg2+, HCO3−, Cl−, and SO42− with a spatial heterogeneity due to the different climates, hydrography, and geology conditions over the region. The main mechanisms that control the water chemistry in the rivers of the Third Pole are natural processes, such as rock weathering, ground discharge, and evaporation-crystallization, and most of the rivers remain pristine. However, it should be noted that due to human factors, such as urbanization and mining operations, toxic elements such as As, Cd, Hg, Mn, and Pb concentrations in some of the rivers in the Third Pole are higher than the permissible limits for drinking water as established by the WHO. With increasing anthropogenic activities and changes within the river basins of the Third Pole, further monitoring of the hydrochemical compositions in rivers over this eco-fragile region is warranted.</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="87629338"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629338"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629338;

The mean mass concentration of PM2.5 (129.8 µg/m3) was only ~25% of TSP mass (558.7 µg/ m3) indicating the dominance of coarser mode aerosols. However, the mean concentration as well as fractional contributions of water-soluble total nitrogen (WSTN) and carbonaceous species reveal their predominance in find-mode aerosols. The mean mass concentration of WSTN was 17.43±4.70 µg/m3 (14%) in PM2.5 and 24.64±8.07 µg/m3 (5%) in TSP. Moreover, the fractional contribution of total carbonaceous aerosols (TCA) is much higher in PM2.5 (~34%) than that in TSP (~20%). The relatively low OC/EC ratio in PM2.5 (3.03 ± 1.47) and TSP (4.64 ± 1.73) suggests fossil fuel combustion as the major sources of carbonaceous aerosols with contributions from secondary organic aerosols. Five-day air mass back trajectories simulated with the HYSPLIT model, together with MODIS fire counts indicate the influence of local emissions as well as transported pollutants from the Indo-Gangetic Plain region to the south of the Himalayan foothills. Principal component analysis (PCA) also suggests a mixed contribution from other local anthropogenic, biomass burning, and crustal sources. Our results highlight that it is necessary to control local emissions as well as regional transport while designing mitigation measures to reduce the KV&#39;s air pollution.</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="87629337"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629337"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629337;

Lifetime Average Daily Dose (LADD), Lifetime lung cancer risk (LLCR) and Incremental lifetime cancer risk (ILCR) were calculated in order to evaluate the cancer risk. PAHs levels were converted to BaP equivalent concentrations (B[a] Peq), and models of health risk assessment were applied. B[a]Peq concentrations exceeded the standard limited value (1 ng/m 3) in all the four sites. The human health risk assessment (HHRA) demonstrated high carcinogenic risk on residents of Bode and Lumbini. Further, LLCR in all sites were over the acceptable range (1.15E-03, 7.90E-04, 1.40E-04 and 9.96E-05, respectively); however, ILCR ranking exhibited acceptable range in Lumbini, Pokhara, and Dhunche (7.10E-06, 1.26E-06, and 8.95E-07). The risk variation among the sites is due to the difference in pollution status. The study shows health risk due to atmospheric PAHs via inhalation prevails all the seasons throughout, differing only seasonally; nevertheless, the concentration and carcinogenic risk decreased remarkably from south-north transect of the central Himalaya. Keeping some uncertainties aside, this study provides noble insights and helps to formulate new advance assessment on the carcinogenic risk of atmospheric PAHs over the Central Himalayas.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="28235b3ec11228eb66bf43b977c1bea4" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91786655,"asset_id":87629335,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91786655/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><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="87629335"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629335"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629335;

The deposition and accumulation of methylmercury (MeHg) in various ecosystems, including the cryospheric components such as snow, meltwater, glaciers, and ice sheet, and subsequently in the food chain pose serious health concerns for living beings. Unlike the abundance of knowledge about the processes of MeHg production over land and oceans, little is known about the sources and production/degradation rate of MeHg in cryosphere systems. In addition, processes controlling the concentration of Hg and MeHg in the cryosphere remains poorly understood, and filling this scientific gap has been challenging. Therefore, it is essential to study and review the deposition and accumulation by biological, physical, and chemical mechanisms involved in Hg methylation in the cryosphere. This review attempts to address knowledge gaps in understanding processes, especially biotic and abiotic, applicable for Hg methylation in the cryosphere. First, we focus on the variability in Hg concentration and mechanisms of Hg methylation, including physical, chemical, microbial, and biological processes, and transportation in the cryosphere. Then, we elaborate on the mechanism of redox reactions and biotic and abiotic factors controlling Hg methylation and biogeochemistry of Hg in the cryosphere. We also present possible mechanisms of Hg methylation with an emphasis on microbial transformation and molecular function to understand variability in Hg concentration in</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="508e595386752bd6177de8d4702115a1" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91786654,"asset_id":87629334,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91786654/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><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="87629334"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629334"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629334;

Yulong in the Tibetan Plateau (TP) makes it a favorable site for mercury (Hg) study. Various snow samples, such as surface snow, snow pit, and snowmelt water were collected from Mt. Yulong in the southeastern TP. The average concentration of Hg was found to be 37 ± 26 ng L −1 (mean ± SD), comparable to Hg concentration from other parts of TP in the same year, though it was comparatively higher than those from previous years, suggesting a possible increase of Hg concentration over the TP. The concentration of Hg was higher in the lower elevation of the glaciers possibly due to the surface melting concentration of particulates. Higher concentration of Hg was observed in the fresh snow, suggesting the possibility of long-range transportation. The average concentration of Hg from the snow pit was 1.49 ± 0.78 ng L −1 , and the concentration of Hg in the vertical profile of the snow pit co-varied with calcium ion (Ca 2+) supporting the fact that the portion of Hg is from the crustal origin. In addition, the principal component analysis (PCA) confirmed that the source of Hg is from the crustal origin; however, the presence of anthropogenic source in the Mt. Yulong was also observed. In surface water around Mt. Yulong, the concentration of Hg T was found in the order of Lashihai Lake > Reservoirs > Rivers > Swamps > Luguhu Lake. In lake water, the concentration of Hg T showed an increasing trend with depth. Overall, the increased concentration of Hg in recent years from the TP can be of concern and may have an adverse impact on the downstream ecosystem, wildlife, and human health.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="ca36a084c67b0bdb910c3852b8f558f7" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91786656,"asset_id":87629333,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91786656/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><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="87629333"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629333"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629333; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=87629333]").text(description); $(".js-view-count[data-work-id=87629333]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 87629333; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='87629333']"); 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></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "ca36a084c67b0bdb910c3852b8f558f7" } } $('.js-work-strip[data-work-id=87629333]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":87629333,"title":"Concentration, spatiotemporal distribution, and sources of mercury in Mt.

The lake series have five lakes, with Lake-1 larger than others. So, Lake-1 was investigated thoroughly during pre-monsoon and post-monsoon seasons. Sediment core was collected from the deepest basin of the Lake-1 during pre-monsoon. Most of the PTM concentrations were higher in the pre-monsoon season; however, Sc, Cr, Cu, Zn, As, and Ag were higher in the post-monsoon. This is an indication that the lake has been impacted either by natural or longrange transported atmospheric pollutants.

The transported pollutants could pose a serious threat to the soil quality in the pristine regions at high elevations having minimal direct human influence. Therefore, it is important to understand the geochemical and physical characteristics of soils in this region and determine the extent of their chemical pollution. In order to achieve these objectives, soil samples were collected from different elevation transects of the Langtang Himalaya in Nepal. The samples were analyzed for PTEs and rare earth elements for the purpose of identifying their possible sources and to evaluate their environmental risk in the region. The PTEs and REEs concentrations were measured by ICP-MS (X-7; Thermo-elemental, USA) and total organic carbon (TOC) by TOC analyzer. The results of this study were comparable to those of the world average background soil as well as the Tibetan plateau surface soil. TOC revealed a decreasing trend with increasing elevation. Correlation analysis and principle component analysis (PCA) indicated that most of the elements were highly associated with major crustal elements, suggesting that their primary sources were of natural origin. Furthermore, the geo-accumulation index (I geo), enrichment factor (EF) and pollution index (PI) analyses indicated that the Himalayan soils represent minimal pollution and the data from this study may be used as background values for the Himalayan region in the future studies. REEs in the soil samples were found to be consistent with an order of average abundance of the Earth's crust. In addition, the chondrite-normalized REE distribution of the light REE suggested enrichment of LREE and Eu depletion. Moreover, this study emphasized that soils of the Himalayan region could, in future, be under threat of elemental pollution from long-range transport via atmospheric circulation and deposition.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="b8f5ee97e6a918f50300e97aaac72f87" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91786657,"asset_id":87629329,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91786657/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><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="87629329"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629329"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629329;

Concentrations of Hg were significantly higher in Lake Gosainkunda compared to Lake Phewa probably due tolong-range transport of Hg and its deposition on high altitudes of the Himalayas, in addition to the probable natural geological sources. Some of the TEs(such as Al, V, Cr, Mn, Fe and Co)show crustal origin in Lake Gosainkunda, whereas others such as Ni, Cu, Zn, Cd, and Pb indicatepossible anthropogenic origin (EF&amp;amp;gt;4). On the other hand, Al, V, Cr, Ni and Cu show crustal origin in Lake Phewa and the remaining TEs (Mn, Fe, Co, Zn, Cd and Pb) showed high EF values relative to the crustal elements suggesting potential anthropogenic inputs of the pollutants.The study further indicates that two studied lakes have different potential sources for Mn, Fe, Co, Ni and Cu regarding TE pollution. A high enrichment of Cd and Pb in high altitude lake (with less anthropogenic activities) compared to the low altitude lake (with high anthropogenic activities) indicates atmospheric long-range transportation of the pollutants in remote areas of the Himalayas which might be possible as air masses pass through the industrial areas and deposit in the high altitudes.</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="87629328"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629328"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629328; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=87629328]").text(description); $(".js-view-count[data-work-id=87629328]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 87629328; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='87629328']"); 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></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.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" } } $('.js-work-strip[data-work-id=87629328]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":87629328,"title":"Mercury and Selected Trace Elements from a Remote (Gosainkunda) and an Urban (Phewa) Lake Waters of Nepal","internal_url":"https://www.academia.edu/87629328/Mercury_and_Selected_Trace_Elements_from_a_Remote_Gosainkunda_and_an_Urban_Phewa_Lake_Waters_of_Nepal","owner_id":208155,"coauthors_can_edit":true,"owner":{"id":208155,"first_name":"Chhatra","middle_initials":null,"last_name":"Sharma","page_name":"ChhatraSharma","domain_name":"tribhuvan","created_at":"2010-06-26T21:40:50.293-07:00","display_name":"Chhatra Sharma","url":"https://tribhuvan.academia.edu/ChhatraSharma"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="87629327"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/87629327/A_Review_of_Riverbed_Extraction_and_its_Effects_on_Aquatic_Environment_with_Special_Reference_to_Tinau_River_Nepal"><img alt="Research paper thumbnail of A Review of Riverbed Extraction and its Effects on Aquatic Environment with Special Reference to Tinau River, Nepal" class="work-thumbnail" src="https://attachments.academia-assets.com/91786651/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/87629327/A_Review_of_Riverbed_Extraction_and_its_Effects_on_Aquatic_Environment_with_Special_Reference_to_Tinau_River_Nepal">A Review of Riverbed Extraction and its Effects on Aquatic Environment with Special Reference to Tinau River, Nepal</a></div><div class="wp-workCard_item"><span>Hydro Nepal: Journal of Water, Energy and Environment</span><span>, 2012</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Rivers not only maintain the ecological balance but also generate resources.

Fishes and riverbed materials such as sand, cobble, pebble, boulders, etc. are the sources of income from natural rivers; and these are the important resources in the construction industry.There exist very few studies on the effects of riverbed extraction in the rivers like Tinau. The lack of generic hydrological and climatic data in the river catchment leads to the lack of knowhow regarding the hydrological behavior of the river basin and its consequences over time. This study is the outcome of the literature review on riverbed extraction and its effects on the aquatic environment particularly in the Tinau River. Riverbed extraction can cause many effects on the environment. But this paper mainly focuses on the effects of riverbed extraction on the hydraulic structures, ground water, river morphology, cost externalization, fish species and fisheries for livelihood.DOI: <a href="http://dx.doi.org/10.3126/hn.v11i0.71" rel="nofollow">http://dx.doi.org/10.3126/hn.v11i0.71</a>...</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="8533df4dd6599941e073ce711c4a7172" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91786651,"asset_id":87629327,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91786651/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><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="87629327"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629327"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629327;

In order to investigate trace elements in atmospheric wet deposition in the southern slope of the Himalayas, precipitation samples were collected for over a year from four stations: Kathmandu (1314m.a.s.l), Dhunche (2065m.a.s.l), Dimsa (3078m.a.s.l) and Gosainkunda (4417m.a.s.l) characterized as urban, semi-urban, rural or remote site, respectively. A total of 221 samples were collected and concentrations of 10 trace elements (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb) were examined. The highest concentrations of elements were found at urban site (Kathmandu) and lowest at remote site (Gosainkunda). The seasonal differences of elemental concentrations in Kathmandu was not clear between monsoon and non-monsoon seasons as local sources predominated over regional sources. On the contrary, the other three sites showed a distinct seasonal variation with higher loadings of trace elements during non-monsoon and lower during monsoon. EFs calculations at all sites showed that most of elements (Cr, Co, Ni, Cu, Zn, Cd and Pb) were from anthropogenic sources and some (Al, Fe and Mn) were originated from crustal sources. Furthermore, principal component analysis (PCA) also indicated that the precipitation chemistry was mostly influenced by crustal and anthropogenic sources in Nepalese Himalayas. The result from the present study is an indication that long-range transport of pollutants has a significant impact on the high altitude remote areas in the central Himalayan regions.

The biodiversity is unique and rich yet not adequately explored and studied. Some studies have been carried out in the Kashmir Himalaya in India followed by Everest Region in Nepal. Most of the studies have dealt with physico-chemical analysis of the water samples; however complete bathymetric and limnological studies have not been performed. The high altitude Himalayan lakes are remote and difficult to access. They are characterized by the presence of glacial silt, low Sechhi values, low conductivity and neutral pH. The most dominant cation and anion in high altitude lakes are Calcium (Ca) and Bicarbonate (HCO3) respectively with few exceptions. Water chemistry of the lakes is dependent on the geolithology of the catchment area.

Water samples were collected from 43 sites of nine lakes, considering the land use patterns, anthropogenic activities, inlets, and outlets. Twenty physico-chemical parameters were analyzed to know the water characteristics and pollution level. The bathymetry map showed that Jingale is the deepest lake (44 m), followed by Batula (15 m) and Mathillo Dhaune (9.5 m). There was no significant spatial variability in the concentration of physicochemical parameters among the sampling sites. The mean concentrations of cations and anions were in the order of Ca&gt; Mg&gt; Na&gt; K, and HCO3&gt; Cl&gt; SO4&gt; PO4&gt; NO3, respectively.

The highest total Hg concentration was found in X. cancila with an average of 800.42(±279.36) µg/kg exceeding the international marketing limit (500 mg/kg), a carnivorous species. However, except for some individuals of N. nandus, total Hg concentrations in other fish species in the present study were significantly lower than that limit. The fish community had at least two trophic levels (Δ15N &gt; 5.6), C. punctatus with the highest and M. vittatus the lowest signatures of δ15N, which was also supported by the stomach content analysis.

In this chapter, an overview of the water chemistry and the geochemical mechanisms that govern the characteristics of major ions and trace elements in rivers of the Third Pole are presented. In general, most rivers of the Third Pole have an alkaline water environment with an average pH of 8.7. As a result of intensive rock weathering within the catchments, the averaged total dissolved solids (~380 mg L−1) in the rivers of the Third Pole are much higher than the global median level. It was found that the dissolved contents in rivers of the Third Pole are dominated by Ca2+, Mg2+, HCO3−, Cl−, and SO42− with a spatial heterogeneity due to the different climates, hydrography, and geology conditions over the region. The main mechanisms that control the water chemistry in the rivers of the Third Pole are natural processes, such as rock weathering, ground discharge, and evaporation-crystallization, and most of the rivers remain pristine. However, it should be noted that due to human factors, such as urbanization and mining operations, toxic elements such as As, Cd, Hg, Mn, and Pb concentrations in some of the rivers in the Third Pole are higher than the permissible limits for drinking water as established by the WHO. With increasing anthropogenic activities and changes within the river basins of the Third Pole, further monitoring of the hydrochemical compositions in rivers over this eco-fragile region is warranted.</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="87629338"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629338"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629338;

The mean mass concentration of PM2.5 (129.8 µg/m3) was only ~25% of TSP mass (558.7 µg/ m3) indicating the dominance of coarser mode aerosols. However, the mean concentration as well as fractional contributions of water-soluble total nitrogen (WSTN) and carbonaceous species reveal their predominance in find-mode aerosols. The mean mass concentration of WSTN was 17.43±4.70 µg/m3 (14%) in PM2.5 and 24.64±8.07 µg/m3 (5%) in TSP. Moreover, the fractional contribution of total carbonaceous aerosols (TCA) is much higher in PM2.5 (~34%) than that in TSP (~20%). The relatively low OC/EC ratio in PM2.5 (3.03 ± 1.47) and TSP (4.64 ± 1.73) suggests fossil fuel combustion as the major sources of carbonaceous aerosols with contributions from secondary organic aerosols. Five-day air mass back trajectories simulated with the HYSPLIT model, together with MODIS fire counts indicate the influence of local emissions as well as transported pollutants from the Indo-Gangetic Plain region to the south of the Himalayan foothills. Principal component analysis (PCA) also suggests a mixed contribution from other local anthropogenic, biomass burning, and crustal sources. Our results highlight that it is necessary to control local emissions as well as regional transport while designing mitigation measures to reduce the KV&#39;s air pollution.</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="87629337"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629337"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629337;

Lifetime Average Daily Dose (LADD), Lifetime lung cancer risk (LLCR) and Incremental lifetime cancer risk (ILCR) were calculated in order to evaluate the cancer risk. PAHs levels were converted to BaP equivalent concentrations (B[a] Peq), and models of health risk assessment were applied. B[a]Peq concentrations exceeded the standard limited value (1 ng/m 3) in all the four sites. The human health risk assessment (HHRA) demonstrated high carcinogenic risk on residents of Bode and Lumbini. Further, LLCR in all sites were over the acceptable range (1.15E-03, 7.90E-04, 1.40E-04 and 9.96E-05, respectively); however, ILCR ranking exhibited acceptable range in Lumbini, Pokhara, and Dhunche (7.10E-06, 1.26E-06, and 8.95E-07). The risk variation among the sites is due to the difference in pollution status. The study shows health risk due to atmospheric PAHs via inhalation prevails all the seasons throughout, differing only seasonally; nevertheless, the concentration and carcinogenic risk decreased remarkably from south-north transect of the central Himalaya. Keeping some uncertainties aside, this study provides noble insights and helps to formulate new advance assessment on the carcinogenic risk of atmospheric PAHs over the Central Himalayas.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="28235b3ec11228eb66bf43b977c1bea4" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91786655,"asset_id":87629335,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91786655/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><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="87629335"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629335"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629335;

The deposition and accumulation of methylmercury (MeHg) in various ecosystems, including the cryospheric components such as snow, meltwater, glaciers, and ice sheet, and subsequently in the food chain pose serious health concerns for living beings. Unlike the abundance of knowledge about the processes of MeHg production over land and oceans, little is known about the sources and production/degradation rate of MeHg in cryosphere systems. In addition, processes controlling the concentration of Hg and MeHg in the cryosphere remains poorly understood, and filling this scientific gap has been challenging. Therefore, it is essential to study and review the deposition and accumulation by biological, physical, and chemical mechanisms involved in Hg methylation in the cryosphere. This review attempts to address knowledge gaps in understanding processes, especially biotic and abiotic, applicable for Hg methylation in the cryosphere. First, we focus on the variability in Hg concentration and mechanisms of Hg methylation, including physical, chemical, microbial, and biological processes, and transportation in the cryosphere. Then, we elaborate on the mechanism of redox reactions and biotic and abiotic factors controlling Hg methylation and biogeochemistry of Hg in the cryosphere. We also present possible mechanisms of Hg methylation with an emphasis on microbial transformation and molecular function to understand variability in Hg concentration in</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="508e595386752bd6177de8d4702115a1" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91786654,"asset_id":87629334,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91786654/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><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="87629334"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629334"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629334;

Yulong in the Tibetan Plateau (TP) makes it a favorable site for mercury (Hg) study. Various snow samples, such as surface snow, snow pit, and snowmelt water were collected from Mt. Yulong in the southeastern TP. The average concentration of Hg was found to be 37 ± 26 ng L −1 (mean ± SD), comparable to Hg concentration from other parts of TP in the same year, though it was comparatively higher than those from previous years, suggesting a possible increase of Hg concentration over the TP. The concentration of Hg was higher in the lower elevation of the glaciers possibly due to the surface melting concentration of particulates. Higher concentration of Hg was observed in the fresh snow, suggesting the possibility of long-range transportation. The average concentration of Hg from the snow pit was 1.49 ± 0.78 ng L −1 , and the concentration of Hg in the vertical profile of the snow pit co-varied with calcium ion (Ca 2+) supporting the fact that the portion of Hg is from the crustal origin. In addition, the principal component analysis (PCA) confirmed that the source of Hg is from the crustal origin; however, the presence of anthropogenic source in the Mt. Yulong was also observed. In surface water around Mt. Yulong, the concentration of Hg T was found in the order of Lashihai Lake > Reservoirs > Rivers > Swamps > Luguhu Lake. In lake water, the concentration of Hg T showed an increasing trend with depth. Overall, the increased concentration of Hg in recent years from the TP can be of concern and may have an adverse impact on the downstream ecosystem, wildlife, and human health.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="ca36a084c67b0bdb910c3852b8f558f7" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91786656,"asset_id":87629333,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91786656/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><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="87629333"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629333"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629333; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=87629333]").text(description); $(".js-view-count[data-work-id=87629333]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 87629333; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='87629333']"); 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></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "ca36a084c67b0bdb910c3852b8f558f7" } } $('.js-work-strip[data-work-id=87629333]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":87629333,"title":"Concentration, spatiotemporal distribution, and sources of mercury in Mt.

The lake series have five lakes, with Lake-1 larger than others. So, Lake-1 was investigated thoroughly during pre-monsoon and post-monsoon seasons. Sediment core was collected from the deepest basin of the Lake-1 during pre-monsoon. Most of the PTM concentrations were higher in the pre-monsoon season; however, Sc, Cr, Cu, Zn, As, and Ag were higher in the post-monsoon. This is an indication that the lake has been impacted either by natural or longrange transported atmospheric pollutants.

The transported pollutants could pose a serious threat to the soil quality in the pristine regions at high elevations having minimal direct human influence. Therefore, it is important to understand the geochemical and physical characteristics of soils in this region and determine the extent of their chemical pollution. In order to achieve these objectives, soil samples were collected from different elevation transects of the Langtang Himalaya in Nepal. The samples were analyzed for PTEs and rare earth elements for the purpose of identifying their possible sources and to evaluate their environmental risk in the region. The PTEs and REEs concentrations were measured by ICP-MS (X-7; Thermo-elemental, USA) and total organic carbon (TOC) by TOC analyzer. The results of this study were comparable to those of the world average background soil as well as the Tibetan plateau surface soil. TOC revealed a decreasing trend with increasing elevation. Correlation analysis and principle component analysis (PCA) indicated that most of the elements were highly associated with major crustal elements, suggesting that their primary sources were of natural origin. Furthermore, the geo-accumulation index (I geo), enrichment factor (EF) and pollution index (PI) analyses indicated that the Himalayan soils represent minimal pollution and the data from this study may be used as background values for the Himalayan region in the future studies. REEs in the soil samples were found to be consistent with an order of average abundance of the Earth's crust. In addition, the chondrite-normalized REE distribution of the light REE suggested enrichment of LREE and Eu depletion. Moreover, this study emphasized that soils of the Himalayan region could, in future, be under threat of elemental pollution from long-range transport via atmospheric circulation and deposition.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="b8f5ee97e6a918f50300e97aaac72f87" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91786657,"asset_id":87629329,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91786657/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><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="87629329"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629329"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629329;

Concentrations of Hg were significantly higher in Lake Gosainkunda compared to Lake Phewa probably due tolong-range transport of Hg and its deposition on high altitudes of the Himalayas, in addition to the probable natural geological sources. Some of the TEs(such as Al, V, Cr, Mn, Fe and Co)show crustal origin in Lake Gosainkunda, whereas others such as Ni, Cu, Zn, Cd, and Pb indicatepossible anthropogenic origin (EF&amp;amp;gt;4). On the other hand, Al, V, Cr, Ni and Cu show crustal origin in Lake Phewa and the remaining TEs (Mn, Fe, Co, Zn, Cd and Pb) showed high EF values relative to the crustal elements suggesting potential anthropogenic inputs of the pollutants.The study further indicates that two studied lakes have different potential sources for Mn, Fe, Co, Ni and Cu regarding TE pollution. A high enrichment of Cd and Pb in high altitude lake (with less anthropogenic activities) compared to the low altitude lake (with high anthropogenic activities) indicates atmospheric long-range transportation of the pollutants in remote areas of the Himalayas which might be possible as air masses pass through the industrial areas and deposit in the high altitudes.</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="87629328"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629328"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629328; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=87629328]").text(description); $(".js-view-count[data-work-id=87629328]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 87629328; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='87629328']"); 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></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.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" } } $('.js-work-strip[data-work-id=87629328]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":87629328,"title":"Mercury and Selected Trace Elements from a Remote (Gosainkunda) and an Urban (Phewa) Lake Waters of Nepal","internal_url":"https://www.academia.edu/87629328/Mercury_and_Selected_Trace_Elements_from_a_Remote_Gosainkunda_and_an_Urban_Phewa_Lake_Waters_of_Nepal","owner_id":208155,"coauthors_can_edit":true,"owner":{"id":208155,"first_name":"Chhatra","middle_initials":null,"last_name":"Sharma","page_name":"ChhatraSharma","domain_name":"tribhuvan","created_at":"2010-06-26T21:40:50.293-07:00","display_name":"Chhatra Sharma","url":"https://tribhuvan.academia.edu/ChhatraSharma"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="87629327"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/87629327/A_Review_of_Riverbed_Extraction_and_its_Effects_on_Aquatic_Environment_with_Special_Reference_to_Tinau_River_Nepal"><img alt="Research paper thumbnail of A Review of Riverbed Extraction and its Effects on Aquatic Environment with Special Reference to Tinau River, Nepal" class="work-thumbnail" src="https://attachments.academia-assets.com/91786651/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/87629327/A_Review_of_Riverbed_Extraction_and_its_Effects_on_Aquatic_Environment_with_Special_Reference_to_Tinau_River_Nepal">A Review of Riverbed Extraction and its Effects on Aquatic Environment with Special Reference to Tinau River, Nepal</a></div><div class="wp-workCard_item"><span>Hydro Nepal: Journal of Water, Energy and Environment</span><span>, 2012</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Rivers not only maintain the ecological balance but also generate resources.

Fishes and riverbed materials such as sand, cobble, pebble, boulders, etc. are the sources of income from natural rivers; and these are the important resources in the construction industry.There exist very few studies on the effects of riverbed extraction in the rivers like Tinau. The lack of generic hydrological and climatic data in the river catchment leads to the lack of knowhow regarding the hydrological behavior of the river basin and its consequences over time. This study is the outcome of the literature review on riverbed extraction and its effects on the aquatic environment particularly in the Tinau River. Riverbed extraction can cause many effects on the environment. But this paper mainly focuses on the effects of riverbed extraction on the hydraulic structures, ground water, river morphology, cost externalization, fish species and fisheries for livelihood.DOI: <a href="http://dx.doi.org/10.3126/hn.v11i0.71" rel="nofollow">http://dx.doi.org/10.3126/hn.v11i0.71</a>...</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="8533df4dd6599941e073ce711c4a7172" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":91786651,"asset_id":87629327,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/91786651/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><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="87629327"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="87629327"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 87629327;

In order to investigate trace elements in atmospheric wet deposition in the southern slope of the Himalayas, precipitation samples were collected for over a year from four stations: Kathmandu (1314m.a.s.l), Dhunche (2065m.a.s.l), Dimsa (3078m.a.s.l) and Gosainkunda (4417m.a.s.l) characterized as urban, semi-urban, rural or remote site, respectively. A total of 221 samples were collected and concentrations of 10 trace elements (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb) were examined. The highest concentrations of elements were found at urban site (Kathmandu) and lowest at remote site (Gosainkunda). The seasonal differences of elemental concentrations in Kathmandu was not clear between monsoon and non-monsoon seasons as local sources predominated over regional sources. On the contrary, the other three sites showed a distinct seasonal variation with higher loadings of trace elements during non-monsoon and lower during monsoon. EFs calculations at all sites showed that most of elements (Cr, Co, Ni, Cu, Zn, Cd and Pb) were from anthropogenic sources and some (Al, Fe and Mn) were originated from crustal sources. Furthermore, principal component analysis (PCA) also indicated that the precipitation chemistry was mostly influenced by crustal and anthropogenic sources in Nepalese Himalayas. The result from the present study is an indication that long-range transport of pollutants has a significant impact on the high altitude remote areas in the central Himalayan regions.

The biodiversity is unique and rich yet not adequately explored and studied. Some studies have been carried out in the Kashmir Himalaya in India followed by Everest Region in Nepal. Most of the studies have dealt with physico-chemical analysis of the water samples; however complete bathymetric and limnological studies have not been performed. The high altitude Himalayan lakes are remote and difficult to access. They are characterized by the presence of glacial silt, low Sechhi values, low conductivity and neutral pH. The most dominant cation and anion in high altitude lakes are Calcium (Ca) and Bicarbonate (HCO3) respectively with few exceptions. Water chemistry of the lakes is dependent on the geolithology of the catchment area.
