摘要
全氟和多氟烷基化合物(PFAS)是近年来备受关注的新污染物,在环境中被广泛检出,有害人类健康,然而目前中国土壤与地下水中的PFAS总体分布情况仍未明晰.通过公开发表的文献,比较了不同地区土壤和地下水中PFAS的浓度、组成与来源,探讨了 PFAS空间分布特点,为全面了解中国土壤与地下水中PFAS分布状况提供依据.PFAS在土壤与地下水中普遍存在,总体上呈现东部沿海地区高于西部地区的特点.工业区(尤其是氟化物制造工厂)等污染点源周边土壤与地下水中PFAS浓度较高.全氟辛酸(PFOA)和全氟辛烷磺酸(PFOS)是中国土壤与地下水中主要的PFAS,但新型PFAS(如全氟丁酸、全氟2-甲基-3-氧杂己酸等)的检出率及浓度不断升高,其环境风险不容忽视.
Abstract
PFAS were emerging pollutants that have caused great attention in recent years.PFAS were widely detected in the environment and posed potential risk to human health.However,the nationwide distribution of PFAS in soil and groundwater remained unclear.Through published literatures,the concentration levels,component characteristics and the sources of PFAS in soil and groundwater were compared in different regions.The spatial distribution of PFAS were discussed.This work would provide insight into the status of PFAS in soil and groundwater across China.PFAS were pervasively existed in the soil and groundwater.In general,the PFAS level was higher in east China of coastal area than the west areas.The PFAS level around point sources,such as industrial area(especially the fluorochemical facilities)was higher than other areas.PFOA and PFOS were still dominant PFAS in the environment,while the content and detection frequency of novel PFAS(such as perfluorobutanoic acid,perfluoro(2-methyl-3-oxahexanoic)acid,etc)was increasing,which could not be neglected.
