Current status of PFAS distribution in soil and groundwater across China
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.
