1硒汞相互作用及机理研究进展显示文摘硒汞相互作用研究在过去近半个世纪以来一直都是汞(硒)环境化学和毒理学及相关学科研究的重要领域之一,尤其在近10年内,对该领域的研究和认识取得了重要突破,国际上几乎每年都会出现与之相关的综述或评论。相比之下,国内期刊报道与之相关的综述文献并不多见。本文对这一领域的研究进展进行了尽可能详尽的系统介绍,并就重要问题阐述了相关观点并提出建议。内容上涵盖了'自然条件环境下硒汞相互作用及机理(包括水生生态系统和陆地生态系统)'、'哺乳动物(及人体)的硒汞相互作用及机理',以及'汞污染风险的新评估模式及相关建议'等三大部分。希望能对国内感兴趣的相关科研人员和环境管理工作者了解该领域的发展和动态起到一定的帮助。张华 冯新斌 王祖光 Thorjфrn Larssen 2013地球与环境2013,41,6:11
2Total mercury in wild fish in Guizhou reservoirs, China显示文摘The health hazard of mercury (Hg) compounds is internationally recognized, and the main pathways for methylmercury (MeHg) intake in humans are through consumption of food, especially fish. Given the large releases of Hg to the environment in China, combined with the fast development of hydropower, this issue deserves attention. Provided similar mobilization pathways of Hg in China as seen in reservoirs in North America and Europe one should expect increased Hg contamination in relation to future hydropower reservoir construction in this country. This study presents total Hg (THg) concentrations in wild fish from six Guizhou reservoirs, China. The THg concentrations in fish were generally low despite high background levels in the bedrock and depositions from local point sources. The over all mean ± SD concentration of THg was (0.066 ± 0.078) μg/g (n = 235). After adjusting for among-reservoir variation in THg, there were significant differences in THg among functional groups of the fish, assumed to re?ect trophic levels. Predicted THg- concentration ratios, retrieved from a mixed linear model, between the functional groups were 9:4:4:1 for carnivorous, omnivorous, planktivorous and herbivorous fish. This result indicated that MeHg accumulation may prevail even under circumstances with short food chains as in this Chinese water system. No fish exceeded recommended maximum THg limit for human consumption set by World Health Organization and the Standardization Administration of China (0.5 μg/g fish wet weight (ww)). Only six fish (2.5%) exceeded the maximum THg limit set by US Environmental Protection Agency (0.3 μg/g fish ww).Haiyu Yan Atle Rustadbakken Heng Yao Thorjorn Larssen Xinbin Feng Ting Liu Lihai Shang Thrond O.

3Minamata Convention on Mercury: Chinese progress and perspectives显示文摘Mercury(Hg)is a global threat to human and environmental health[1].To address this global issue,the Minamata Convention on Mercury(MC)was agreed upon by 128 countries on 19January 2013.China officially ratified the MC in August 2016.As the largest emit-Yan Lin Shuxiao Wang Eirik Hovland Steindal Hua Zhang Huan Zhong Yindong Tong Zuguang Wang Hans Fredrik Veiteberg Braaten Qingru Wu ThorjФrn Larssen 2017National Science Review2017,4,5:3

6Decreasing mercury levels in consumer fish over the three decades of increasing mercury emissions in China显示文摘Fish consumption is the primary dietary route of human exposure to methylmercury.It has been well documented that elevated mercury concentration in fish in North America and Europe is linked to anthropogenic mercury emissions.China is the world’s largest producer,consumer,and emitter of mercury,as well as the world’s largest commercial fish producer and consumer.Although mercury pollution in fish in China is currently receiving much attention worldwide,its status remains largely unknown.Here,we conducted a meta-analysis on total mercury concentrations in marine and freshwater fish samples,covering 35,464 samples collected in China over the past 30 years.It is found that,opposite to the increasing emission and documented mercury contamination events,mercury levels in fish have gradually decreased in China over the past 30 years.The results were in sharp contrast to those found in North America and Europe.The mercury concentrations in fish were significantly anticorrelated with the fish catch and fish aquaculture and were inverse to trophic levels.Overfishing and the short lifecycle of aquaculture fish,both reducing the trophic level and the duration of mercury accumulation,were the most likely causes leading to the decline of mercury concentrations found in fish in China.Hua Zhang Wenxiong Wang Chejen Lin Xinbin Feng Jianbo Shi Guibin Jiang Thorjørn Larssen 2022Eco-Environment & Health2022,1,1:2
