摘要:全氟化合物(perfluorinated compounds,PFCs)因具有持久性、生物蓄积性和毒性,近年来得到全世界的广泛关注。我国对PFCs环境污染水平的研究主要集中在污水、河水、湖水等浓度较高的水体,针对地下水中PFCs的存在情况研究较为缺乏。为了解北京市地下水中PFCs的污染水平,采集和分析了6个采样地段26眼监测井中的地下水。结果表明:18种目标PFCs中有11种存在不同程度的检出,以C4~C9的全氟羧酸(

Abstract:Perfluorinated compounds (PFCs) have received extensive concerns due to their persistence, bioaccumulation and toxicity in recent years. Previous studies about the PFCs contamination in China mainly focused on the wastewater, river water or lake water, which contain relatively higher PFCs concentrations. Very limited data about the situation of PFCs in groundwater is now available. In the present study, 26 groundwater monitoring wells from six areas of Beijing were sampled and investigated for the PFCs occurrence. As the result, 11 of totally 18 target PFCs were detected in one or more wells. The dominant compounds were C4-C9 perfluorocarboxylic acids (
