摘　　要：全氟辛烷磺酸(perfluorooctane sulphonate,PFOS)属于全氟及多氟烷基化合物(per-and polyfluoroalkyl substances,PFASs),是持久性有机污染物的一种,已经被各国禁用。作为PFOS的替代品,全氟壬烯基苯磺酸钠(sodium p-perfluorinated noneoxybenzen sulfonate,OBS)已经在中国被广泛生产使用,并已在环境和人体中检出。本文对已有的PFOS及OBS的研究进行综述,总结了它们的环境行为、人群暴露、毒性效应,建议虽然OBS的生物蓄积性弱于PFOS,但OBS的生物毒性依然值得关注。本文还对该综述存在的局限性进行了讨论并对今后的研究方向做了展望。Perfluorooctane sulfonate(PFOS)belongs to perfluorinated and polyfluoroalkyl compounds(PFASs),and is a persistent organic pollutant that has been banned worldwide.As a substitute for PFOS,sodium p-perfluorinated noneoxybenzenesulfonate(OBS)has been widely produced and used in China,and has been detected in v arious environment media and human body.This article conducts a review of existing research on PFOS and OBS,summarizing their environmental behavior,population exposure,and toxic effects.It is recommended that although the bioaccumulation of OBS is weaker than that of PFOS,the biological toxicity of OBS still deserves attention.This article also discusses the limitations of this review and provides prospects for future research directions.
