水库汞生物地球化学循环研究进展

Developments in the biogeochemical cycle of mercury in reservoirs

对近年来国内外有关水库汞生物地球化学循环的研究现状进行了综述,主要从基质释汞行为、汞释放对水体的影响、汞在水库水生食物链中的迁移富集和水库对河流汞输送的影响等四个方面进行了探讨,并指出该领域研究工作的薄弱环节及发展方向。

The development in mercury bi emical cycle in hydroelectric reservoirs both at home and abroad is reviewed in this paper. Basically, it contains four aspects, namely, the substrate mercury release behavior, the impact of mercury release on the water column, the transfer and bioaccumulation of mercury in the aquatic food chain and the reservoir＇s effect on the mercury distribution in the river. On these basis, the development tendency of this research is proposed since there is still some confusion and obscurity.
