Abstract:In this study, 15 soil samples were collected near a chemical industrial park. The occurrence and spatial distribution of 12 PFASs were analyzed. Principle component analysis and correlation analysis were used to calculate the relationships between individual PFAS. In addition, the potential risks to human health resulted from PFASs in the soil were evaluated by the CSOIL model. The results showed that C4-C7 short chain perfluoroalkyl carboxylic acids (PFCAs) were dominant compounds, especially perfluorobutanoic acid and perfluoropentanoic acid, which were at levels of tens to hundreds ng/g levels. The PFASs concentrations were relatively high in the soils near the CIP and those located at the downwind direction of the CIP, which was due to the close distance to the CIP and the contribution of atmospheric precipitation. It was concluded that short-chain PFCAs may resulted from the industrial activities, while the local agricultural and domestic activities did not have significant contributions to the PFAS in the soil. The estimated daily intake of PFASs in soil via ingestion, inhalation, and dermal uptake were much lower than the health-based guidelines issued by several international regulatory agencies, implying a relatively lower human health risk from the PFASs in the soil.
