摘　　要：桡足类是海洋浮游动物种群的主要组成部分和重要的初级消费者,重金属污染对其影响可通过食物链传递到其他海洋生物甚至人类。综述了近20 a来重金属对桡足类影响的研究进展,包括重金属对桡足类的毒性和生理效应,重金属在桡足类体内蓄积及桡足类体内重金属的食物链(网)传递。并指出今后的研究重点:桡足类体内致毒重金属的存在形式,重金属食物暴露对桡足类生理生化影响机理,以及重金属对桡足类生活史的影响。Marine copepods are the important components of marine zooplankton as well as the primary consumers in marine ecosystem.The contamination of marine copepods by heavy metals can significantly affect other marine organisms or even human beings through food chains accumulation and transfer.This paper reviewed the physiological responses to the toxicity of heavy metals and the accumulation of metals in copepods,in addition of trophic transfer.We also point out some directions for further study,including the toxic speciation of heavy metals in copepods,the physiological and biochemical effects of dietborne metals,and further more,the impacts of heavy metals on copepods life history.
