新型有机污染物氯代多环芳烃的研究进展

Research Progress on New Type Organic Contaminants—Chlorinated Polycyclic Aromatic Hydrocarbons

氯代多环芳烃(Cl-PAHs)是城市大气中发现的卤代有机污染物中的一类。作为一种新型有机污染物,Cl-PAHs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。作者将从Cl-PAHs的毒性作用、形成机理、来源、浓度水平、环境行为等几个方面综述国内外关于Cl-PAHs的研究现状和最新进展。

Chlorinated polycyclic aromatic hydrocarbons （Cl-PAHs） is a kind of halogenated organic pollutions in urban atmospheric. As a new type of organic pollutants, CIPAHs has the similar toxic effect with the dioxin and widely exists in the environmental media, which poses a potential threat to the ecological environment and human health. The current situation and latest research progress of Cl-PAHs on toxic effect, formation mechanism, the source of Cl-PAHs, contamination level, and environmental behaviors are presented in this paper.
