| 2 | Mercury in alpine fish from four rivers in the Tibetan Plateau显示文摘As a global pollutant, high levels of mercury(Hg) have been found in remote ecosystem due to the long range atmospheric transport. In this study, a total of 60 fish samples were collected from four rivers across the Tibetan Plateau to study the accumulation of Hg in remote and high-altitude aquatic environment. The total Hg(THg) and methylmercury(MeHg) in fish muscles ranged from 11 to 2097 ng/g dry weight(dw)(average: 819 ng/g dw)and from 14 to 1960 ng/g dw(average: 756 ng/g dw), respectively. Significantly positive linear relationships were observed between the THg(r = 0.591, p < 0.01, n = 36) and MeHg concentrations(r = 0.473, p < 0.01, n = 36) with the trophic level of fish from Lhasa River,suggesting trophic transfer and biomagnification of Hg in this aquatic ecosystem. Moreover,the THg levels in fish had significantly positive correlations with the length(r = 0.316,p < 0.05, n = 60) and weight(r = 0.271, p < 0.05, n = 60) of fish. The high levels of Hg were attributed to the slow growth and long lifespan of the fish under this sterile and cold environment. Risk assessment revealed that the consumption of Oxygymnocypris stewartii,Schizothorax macropogon, Schizothorax waltoni, Schizopygopsis younghusbandi and Schizothorax o'connori would lead to a high exposure to Me Hg. | Junjuan Shao Jianbo Shi Bu Duo Chengbin Liu Yan Gao Jianjie Fu Ruiqiang Yang Guibin Jiang | 2016 | Journal of Environmental Sciences2016，28，1： | 1 |
