摘　　要：全氟化合物作为新污染物的一类,广泛存在并分布于全球环境中,其中全氟酮类化合物(PFKs)和酰氟类化合物(AFCs)作为一类挥发性全氟化合物具有一定的大气反应活性和环境降解能力而备受关注.然而,PFKs和AFCs的环境降解产物仍然存在难降解、可远距离迁移、具有一定的环境持久性和较强气候影响等特点.本文总结了PFKs和AFCs的主要特征和环境污染来源,重点讨论了大气中PFKs和AFCs的迁移转化过程,并综述了两类全氟化合物及相关产物的环境气候影响,最后提出在新型挥发性全氟化合物的研究过程中亟待解决的问题.Perfluorinated compounds,as a class of emerging contaminants,are widely distributed and observed in global environment,among which the volatile perfluorinated ketones(PFKs)and acyl fluorinated compounds(AFCs)have attracted much attention for their atmospheric reactivity and environmental degradation ability.However,the environmental degradation products of PFKs and AFCs are still characterized by difficult degradation,long-range transport,environmental persistence and strong climatic effects.This study summarizes the main characteristics and sources of PFKs and AFCs,focuses on the transport and reaction of PFKs and AFCs in the atmosphere,and reviews the environmental and the climate impacts of two perfluorinated compounds as well as related products.Finally,the problems that need to be solved in the research of volatile perfluorinated compounds are proposed.
