Tibetan Plateau is located at a mountain region isolated from direct anthropogenic sources. Mercury concentrations and stable isotopes of carbon, nitrogen, and mercury were analyzed in sediment and biota for Nam Co and Yamdrok Lake. Biotic mercury concentrations and high food web magnification factors suggested that Tibetan Plateau is no longer a pristine site. The primary source of methylmercury was microbial production in local sediment despite the lack of direct methylmercury input. Strong… 
Stable carbon and nitrogen isotope evidence for the low biomagnification of mercury in marine fish from the South China Sea
The low biomagnification of total mercury (THg) and methylmercury (MeHg) in commercially important marine fish from the south coast of China has been demonstrated through the analysis of stable
Using Mercury Isotopes To Understand Mercury Accumulation in the Montane Forest Floor of the Eastern Tibetan Plateau.
Correlation analyses of Δ199Hg versus total carbon and leaf area index suggest that litter biomass production is a predominant factor in atmospheric Hg inputs to the forest floor, as evidenced by the negative Δ 199Hg found in the surface soil samples.
Transfer of marine mercury to mountain lakes
Stocking acts a humanly induced biovector that transfers marine Hg to freshwater ecosystems, which is seen in the Hg-isotopic signature up to five years after stocking events occurred, which points to the need of further investigations of the role of stocking in MeHg exposure to freshwater ecosystem.
Insights into Mercury Source Identification and Bioaccumulation Using Stable Isotope Approaches in the Hannibal Pool of the Ohio River, USA
This study highlights the complexity of Hg cycling within an industrialized river and shows that an isotope tracer approach can provide insight to water column sources of HG.
Chemical and Physical Controls on Mercury Source Signatures in Stream Fish from the Northeastern United States.
The multivariable approach of analyzing watershed characteristics and stream chemistry reveals that the Hg isotope composition in fish is linked to current and historic Hg sources in the northeastern U.S. and can be used to trace bioaccumulated Hg.
Evaluating the Application of Photochemical Mass-Independent Fractionation of Mercury (Hg) in Natural Systems
Mercury (Hg) is a toxic and globally distributed contaminant that poses a serious risk to humans, wildlife, and the environment due to its ability to bioaccumulate along the food webs in aquatic


Variation in terrestrial and aquatic sources of methylmercury in stream predators as revealed by stable mercury isotopes.
This study examined stable isotope ratios of MeHg in benthic invertebrates, juvenile steelhead trout, and water striders along a stream productivity gradient, in a forested watershed at the headwater of South Fork Eel River in northern California to suggest that direct terrestrial subsidy can enhance MeHG bioaccumulation of consumers in headwater streams where aqueous Mehg levels are very low.
Mercury Isotope Study of Sources and Exposure Pathways of Methylmercury in Estuarine Food Webs in the Northeastern U.S.
Hg isotopes can be used to identify multiple anthropogenic inorganic Hg andMMHg sources and determine the degree of photodegradation of MMHg in estuarine food webs, indicating that MMHG is photodegraded to varying degrees prior to entry into the food web.
Use of Stable Isotope Signatures to Determine Mercury Sources in the Great Lakes
Sources of mercury (Hg) in Great Lakes sediments were assessed with stable Hg isotope ratios using multicollector inductively coupled plasma mass spectrometry. An isotopic mixing model based on
Mercury Isotopes in Earth and Environmental Sciences
Virtually all biotic, dark abiotic, and photochemical transformations of mercury (Hg) produce Hg isotope fractionation, which can be either mass dependent (MDF) or mass independent (MIF). The largest
Tracing sources and bioaccumulation of mercury in fish of Lake Baikal--Angara River using Hg isotopic composition.
Hg isotopic composition can be used to track the contribution of anthropogenic sources in fish from a contaminated lake, and it is demonstrated that MIF in fish samples from Bratsk Water Reservoir allow to trace anthropogenic Hg.
Mercury stable isotopes in sediments and largemouth bass from Florida lakes, USA.
Sources and transfers of methylmercury in adjacent river and forest food webs.
Stable Hg isotope compositions in food webs in a river and an adjacent forest in northern California are reported and the utility of HG isotopes for studying MeHg sources and cross-habitat transfers is demonstrated.
Stable isotope (N, C, Hg) study of methylmercury sources and trophic transfer in the northern gulf of Mexico.
We combined N, C, and Hg stable isotope measurements to identify the most important factors that influence MeHg accumulation in fish from the northern Gulf of Mexico (nGOM), and to determine if
Mercury isotopes link mercury in San Francisco Bay forage fish to surface sediments.
This study measured the Hg stable isotope compositions of two nearshore fish species and compared them with previously reported analyses of colocated intertidal surface sediments, suggesting that sediment is a primary source of Hg to the nearshore aquatic food web.
