甲基汞是一种剧毒物质,它的生物富集性和生物放大性引起人们的广泛关注.文章综述了甲基汞在海洋中的来源和去除、转化途径,着重对甲基汞的生成机理做了论述,并讨论影响甲基汞生成的(甲基汞反应场所、甲基化细菌、硫酸盐浓度、营养程度等)条件的具体影响机理.%Methylmercury is a highly toxic substance,its bioaccumulation and bio-magnification cause widespread concern.In this paper,the source and removal of methylmercury in the ocean and the mechanism of methylmercury were discussed,and the specific impact mechanism of several conditions (methylmercury reaction sites,methylated bacteria,sulfate concentration,nu-tritional level,etc.)affecting methylmercury production were also discussed.
