摘　　要：重金属镉是一种常见水环境污染物,具有难降解、易残留和不可逆性等特点,综述了重金属镉对鱼类的影响,通过分析镉对鱼类个体、抗氧化系统、组织结构和基因表达的毒性效应,来阐述镉对鱼类的影响机制。Heavy metal Cadmium（Cd） is a widespread aquatic environmental pollutant which is hard to degrade, easy to reside and irreversible. In this study, the effects of heavy metal Cd on fish were reviewed. The influencing mechanisms of Cd to fish were expounded through the analysis of the toxicity effects of Cd on individual fish, antioxidant system, tissue sections and gene expression.
