摘要
综述了国内外对水库生态系统汞的生物地球化学研究的进展,强调了汞问题仍然是水生生态系统环境研究面对的长久挑战,提出了水库可能是高度风险的甲基汞污染"敏感生态系统"的观点,指出水库中汞迁移转化的生物地球化学和水库水生生态系统食物链上汞迁移转化的动力学是水库水生生态系统汞的生物地球化学循环研究的关键问题。
This paper reviewed the progress on current understanding of mercury biogeochemical cycling in reservoirs.It is pointed out that mercury pollution in aquatic systems is a long-lasting challenge for aquatic sciences.Reservoir is recognized as a sensitive ecosystem for mercury methy-lation and subsequently for mercury pollution.The biogeochemistry of mercury transport and transformation in reservoir and the dynamics of mercury bioaccumulation in food chains of the reservoirs are key scientific questions for the research area of mercury biogeochemical cycling in reservoir.
