中科院地化所冯新斌团队以贵州省万山汞矿区不同污染类型(土法炼汞区和废弃汞矿区)的水稻田为研究对象,对汞矿区水稻田各介质中汞的分布特征、主要来源及污染状况进行了全面系统的研究。相关成果日前发表于《环境污染》《生物地球科学》。科研人员对汞矿区稻田土壤汞的甲基化速率/去甲基化速率进行了测定,发现汞矿区稻田土壤中的甲基汞主要来源于自身无机汞的甲基化过程,外源输入可以忽略;土法 Feng Xinbin from the Institute of Geochemistry, Chinese Academy of Sciences, took the paddy fields of different polluting types (indigenous mercury and waste mercury mining areas) of Wanshan mercury mining area in Guizhou Province as the research object. The distribution characteristics of mercury in each paddy field in mercury mining area, Pollution situation conducted a comprehensive and systematic study. Related results recently published in the “Environmental Pollution” “bio-geosciences.” Researchers measured the methylation rate / demethylation rate of mercury in paddy soils in mercury mining areas. It was found that the methylmercury in paddy soil of mercury mining area mainly came from the methylation of inorganic mercury, and the exogenous input was negligible ; Soil law
