全(多)氟烷基化合物生态风险及其管控政策研究
Research on Ecological Risks and Its Control Policies of Per-and Polyfluoroalkyl Substances
摘要
Abstract
Per-and polyfluoroalkyl substances(PFASs)are a typical group of persistent organic pollutants widely distributed in environmental and biological media.Their potential toxicity poses a serious threat to the ecological and environmental safety of the country.In recent years,these chemicals have attracted significant attention and have been included on the list of emerging pollutants in China.To improve the chemical management system and promptly respond to the environmental hazards of PFASs,maintain China's ecological security,and protect the new development pattern with a new safety system,this study summarized the types and physicochemical properties of PFASs and the pollution status of these pollutants in environmental media such as ambient air in industrial,non-industrial,and polar regions,surface water,tap water,drinking water,site soil,farmland soil,and biological media such as human tissues and mammals.In addition,a risk quotient(RQs)approach was used to assess the ecological risk of PFASs based on the pollution status of PFASs in the water and soil environments in some regions of China.A higher ecological risk from PFASs has been found in some water bodies and around industrial fluoride parks,which could pose a significant threat to the country's ecological safety.Second,PFASs toxicity mainly manifests as neurotoxicity,immunotoxicity,reproductive toxicity,hepatorenal toxicity,pulmonary toxicity,and endocrine disruption.Toxicity mechanisms include imbalanced intracellular calcium homeostasis,regulation of cellular signaling pathways,and interaction with nuclear receptors.Finally,recent policy measures to control PFASs and the effects of the implementation of some measures in the United States,the European Union,and Japan were introduced,the formulation and implementation experience was summarized,and the control and governance mechanisms of PFASs were analyzed from the aspects of science and technology,economy,and politics compared with China's national conditions,leading to opinions and suggestions for future research on the control of emerging pollutants,such as PFASs.This study provides an overview of material properties,associated toxicities,ecological risks,and control measures for PFASs.It emphasizes the importance of controlling PFASs,and provides new ideas and foundations for the treatment and control of emerging pollutants such as PFASs in the future.关键词
