摘　　要：水体沉积物重金属污染是一个世界性的环境污染难题,水体中的沉积物重金属污染物由于其不易被分解的特性,不仅持续对水体和水生生物造成危害,而且当其所处的环境发生变化时还会对水体造成二次污染,严重危害到人类健康和生态环境。本文通过对国内外沉积物重金属污染的归纳研究,分析总结了沉积物重金属污染的来源和危害,并主要列举了两种沉积物重金属评价方法:污染负荷指数法和地累积指数法的优缺点和适用范围。Heavy metal pollution in water sediments is a worldwide environmental pollution problem.Because of its difficult decomposition,heavy metal pollutants in water sediments not only continue to cause harm to water bodies and aquatic organisms,but also cause secondary pollution to water bodies when their environment changes,seriously endangering human health and ecological environment.In this paper,the sources and harms of heavy metal pollution in sediments are analyzed and summarized through the inductive study of heavy metal pollution in sediments at home and abroad,and the advantages,disadvantages and application scope of two heavy metal evaluation methods in sediments:pollution load index method and geoaccumulation index method are mainly listed.
