摘　　要：重金属作为一种典型环境污染物,一直都是生态毒理学研究的热点问题。重金属广泛分布于土壤和各类水体中,具有持久性、不可降解性以及生物毒性,通过食物链的途径最终危及人体健康。水生生物作为生物圈中数目繁多、种类庞大的生物群体,其中动植物及微生物对重金属物质存在一定的聚积、浓缩作用,部分水生生物由于具有对毒物反应的高敏感性,成为从事相关研究最贴合实际的受试生物。本文概述了目前重金属对于水生生物的生态毒理学研究进展,旨在对重金属污染监测以及生态风险防控提供参考依据。As a typical pollutant in the environment,heavy metals have always been a hot topic in the field of ecotoxicology.Heavy metals widely exist in soil and water,which are persistent,non-degradable and biotoxic,and ultimately endanger human health through the food chain.Aquatic organisms as a large number of biosphere,a large variety of biological groups,animals,plants and microorganisms have a certain amount of accumulation of heavy metals,concentration of some of the aquatic organisms due to their high sensitivity to toxicological reaction,become the most suitable for the actual study of related organisms.In order to provide a reference for heavy metal pollution monitoring and ecological risk prevention and control,this paper summarizes the current research progress on the ecotoxicology of heavy metals to aquatic organisms.
