全氟化合物的污染现状及国内外研究进展

全氟化合物是环境中一种新型的持久性有机污染物,近年来这类化合物已在全世界范围内的各类环境介质和生物体内被检出,其具有的多种毒性效应已对生态系统和人类造成了一定的威胁,因此有必要对其环境行为进行研究。综述了全氟化合物在水体、沉积物、生物体内的污染现状,总结了目前国内外关于全氟化合物的检测方法、生物毒性、去除技术以及在沉积物中的迁移规律等环境行为的研究进展,并指出了目前研究存在的问题及发展趋势,以期为今后的研究提供参考。

POLLUTION STATUS AND RELATED RESEARCH PROGRESS OF PERFLUORINATED COMPOUNDS

As a new type of persistent organic pollutants in the environment,perfluorinated compounds can be detected in different types of media such as water,sediment,biota samples,human,etc.The widespread occurrence of PFCs is an important environmental problem (globally distributed,environmental persistent,bioaccumulative,and potentially harmful) that requires a multifaceted approach of their environmental behavior.To provide reference for further related researches,the pollution actuality of PFCs was studied,and the research progress at home and abroad on detection method,biotoxcity,removal technology,and transport were summarized.Furthermore,several problems in the research were pointed out,and some advices for the future research were given.
