摘　　要：水环境中的汞存在多种形态,其中甲基汞是环境中汞的一种最重要的存在形态,是唯一能在水生食物链中富集放大的形态,也是汞的各形态中毒性最强的一类污染物。沉积物作为水环境的重要成分,是汞富集的重要场所,也是环境中甲基汞生成的重要场所。本文主要综述了近岸海域沉积物中汞的化学形态研究进展,以期为进一步深入研究沉积物中汞的生物地球化学行为提供参考。Mercury has a variety of forms in water environment. Methyl mercury is the most important mercury in the environment, and it is the only one form of mercury which can enrich and enlarge in the aquatic food chain,as well as the most toxic pollutant of all forms of mercury. As an important component of water environment, sediment is an important place for enrichment of mercury, and also an important place for the formation of methyl mercury in the environment. In this paper, research progress on chemical forms of mercury in nearshore sediments was reviewed, so as to provide references, for further study of biogeochemieal behavior of mercury in sediments.
