Per- and Polyfluoroalkyl Substances in Surface Water of Fuyang River (Handan Section): Occurrence, Source Apportionment, and Risk Assessment

Perfluorinated and polyfluoroalkyl substances (PFASs), as an emerging type of pollutant, always pollute water quality to a certain extent. The occurrence, source, and risk of PFASs in the Fuyang River are not well understood. For the first time, the state of PFASs in the upper Fuyang River (Handan section) was investigated. The results showed that there were 10 types of PFASs with concentrations higher than the limit of quantitation in the surface water of the Fuyang River. The surface waterρ(∑PFASs) ranges from 13.80 to 22.88ng·L−1. The highest quality score is perfluorooctane sulfonate (PFOS), which is 59.40%. PFASs are mainly composed of long-chain substances. PFASs generally show a trend of gradually increasing downstream. PFASs have the same source, mainly from industrial activities around rivers and rainfall inputs. Principal component analysis shows that PFASs mainly come from the leather and textile manufacturing industries, fluoropolymer production, and electroplating metal industries. The concentration of PFASs in the Fuyang River has not yet affected ecology and health.
