持久性有机污染物对鱼类生态毒性研究进展

Research Progress of the Eco-toxicity Effect of Persistent Organic Pollutants to Fish

持久性有机污染物(POPs)具有高毒、持久、生物积累、迁移等特性,严重威胁环境生物和人类健康。水体是持久性有机污染物在环境中迁移转化的重要介质。POPs长期存在于水体中,对不同种类水生生物的生长、发育及生殖产生影响。鱼类作为水生态系统中最主要的脊椎动物,有极其重要的环境指示作用。结合近年来国内外的研究,从急性毒性、发育毒性、神经和行为毒性、内分泌干扰作用等方面对POPs对鱼类的生态毒性进行了综述,为揭示持久性有机污染物的生态毒理效应提供理论依据。

Persistent organic pollutants（ POPs） that have four characteristics including persistent,high toxicity,biological accumulative and migrative,are threat to the health of human and environmental animals. Water body is an important medium for the transformation of POPs in the environment. In water body,POPs can affect the growth,development and reproduction of aquatic organisms through migration,adsorption,sedimentation and food chain. Fish are the main aquatic vertebrates and is also a very important indicator of water environment. This paper is a review of the recent eco-toxicology research of POPs,including acute toxicity,developmental toxicity,nervous system and behavioral effect as well as endocrine alteration. This work can provide theoretical evidence for revealing the eco-toxic effect of POPs and the safety assessment of aquatic ecosystem.
