摘要
多环芳烃衍生物是一类已被证实比多环芳烃具有更强"三致作用"(致癌、致畸和致基因突变)的环境污染物,它广泛存在于环境介质中,特别是大气颗粒物中。氯代多环芳烃(Cl-PAHs)是城市大气中发现的多环芳烃衍生物中的一种,具有与二噁英相似的毒性作用,并且在各环境介质中广泛存在,对生态环境和人体健康造成潜在的威胁。本文将从Cl-PAHs的毒性作用、形成机理、来源及污染水平、风险评估等几个方面综述国内外关于Cl-PAHs的研究现状和最新进展。
PAHs erivatives have been confirmed to have stronger carcinogenic, teratogenic and mutagenic effect than PAHs. They exist widely in environmental media, especially in atmospheric particulates. Chlorinated polycyclic aromatic hydrocarbons(Cl-PAHs) is a kind of polycyclic aromatic compounds found in atmosphere of the city which has similar toxicity with dioxin. Cl-PAHs widely exist in various environmental media as potential threat to ecological environment and human health. The paper discusses the research condition of Cl-PAHs in China and abroad in toxic effect, formation mechanism, source, pollution level and risk assessment.
