摘　　要：全氟辛烷磺酸(perfluorooctane sulphonate,PFOS)类物质是随人类活动而出现的新型持久性有机污染物,其污染在世界各地均有检出.PFOS由含氟污水厂排放污水、工业生产PFOS物质或前体、大气沉降等方式进入环境中,主要分布于水体以及底泥中.水体中PFOS污染主要发生在人口密集、工业发达区域以及污水处理厂周边.底泥中PFOS的吸附量影响因素有pH值、阴阳离子表面活性剂及盐浓度.通过调研现阶段国内外有关PFOS的文献,综述PFOS在水体及底泥环境中的污染特性.Perfluorooctane sulphonate （PFOS） is a new type of persistent organic contaminants caused by human living and detected throughout the world. PFOS enters into the environment through fluorine- containing wastewater treatment plant discharges, industrial production of PFOS or its precursors, atmospheric deposition, etc. It is mainly distributed in water and sediments. The PFOS contamination occurs mainly in densely populated and industrialized regions, and areas surrounded water treatment plants. The adsorption of PFOS is affected by pH, cation or anion surfactants, and concentration of salts. This paper analyzes recent domestic and international literature and studies PFOS to give a summary of PFOS pollution characteristics in water and sediment environments.
