Rapid urbanization may lead to per- and polyfluoroalkyl substances (PFAS) pollution. Baiyangdian Basin has undergone rapid urbanization; will this comprehensively and persistently exacerbate PFAS pollution? To address this question, this study reviews the occurrence characteristics of PFAS in Baiyangdian Basin. From 2008 to 2019, PFAS concentrations in sediments, aquatic plants, and aquatic animals (including aquatic products) in Baiyangdian Basin demonstrated an overall upward trend. Specifically, the PFAS concentration in water increased by 78.54 times (2008–2017), but decreased by 53.53% (2017–2019). Compared with 2008, the PFAS concentrations in sediments, aquatic plants, and aquatic animals in 2019 increased by 21.41 times, 1.037–1.507 times, and 6.55 times, respectively. It can be seen that rapid urban development has not comprehensively and persistently exacerbated PFAS pollution in Baiyangdian Basin, which is related to the implementation of ecological restoration in Baiyangdian Basin. Furthermore, the remediation of PFAS pollution in Baiyangdian Basin should be carried out continuously. This study enhances our comprehension of the current status and remediation of PFAS pollution in Baiyangdian Basin under the background of rapid urbanization, and provides a theoretical basis for future research.

摘要

Rapid urbanization may lead to per- and polyfluoroalkyl substances (PFAS) pollution. Baiyangdian Basin has undergone rapid urbanization; will this comprehensively and persistently exacerbate PFAS pollution? To address this question, this study reviews the occurrence characteristics of PFAS in Baiyangdian Basin. From 2008 to 2019, PFAS concentrations in sediments, aquatic plants, and aquatic animals (including aquatic products) in Baiyangdian Basin demonstrated an overall upward trend. Specifically, the PFAS concentration in water increased by 78.54 times (2008–2017), but decreased by 53.53% (2017–2019). Compared with 2008, the PFAS concentrations in sediments, aquatic plants, and aquatic animals in 2019 increased by 21.41 times, 1.037–1.507 times, and 6.55 times, respectively. It can be seen that rapid urban development has not comprehensively and persistently exacerbated PFAS pollution in Baiyangdian Basin, which is related to the implementation of ecological restoration in Baiyangdian Basin. Furthermore, the remediation of PFAS pollution in Baiyangdian Basin should be carried out continuously. This study enhances our comprehension of the current status and remediation of PFAS pollution in Baiyangdian Basin under the background of rapid urbanization, and provides a theoretical basis for future research.
