Abstract

ABSTRACT Fluorine industry parks (FIPs) play a fundamental role in the advancement of China’s fluorine industry. In this study, Target analysis was combined with traceability analysis to determine the type of PFASs present in the surface water and sediment around FIPs in China. Meanwhile, the risk they posed to the surrounding river was examined through risk characterisation ratio. Among the areas surveyed, 10 and 15 PFASs were detected in the surface water and sediment, with concentrations of up to 32,674.0 ng/L and 17.84 ng/g, respectively. There were a larger proportion of short-chain PFASs (C4-C7), and perfluoropentanoic acid was particularly prevalent. Source analysis indicates that the PFASs in the surface water may have originated from precursor degradation and atmospheric deposition. The fluorine rubber industry was the main source for the sediment PFASs, particularly for short-chain compounds. A risk characterisation ratio analysis identified perfluorododecanoic acid, perfluorobutane sulfonate, perfluoroheptanoic acid, perfluoropentanoic acid, and perfluorohexanoic acid as compounds with relatively high risks.

期刊介绍： Environmental Pollutants & Bioavailability is a peer-reviewed open access forum for insights on the chemical aspects of pollutants in the environment and biota, and their impacts on the uptake of the substances by living organisms. Topics include the occurrence, distribution, transport, transformation, transfer, fate, and effects of environmental pollutants, as well as their impact on living organisms. Substances of interests include heavy metals, persistent organic pollutants, and emerging contaminants, such as engineered nanomaterials, as well as pharmaceuticals and personal-care products as pollutants.
