土壤和水环境全氟及多氟化合物预测无效应浓度推导及生态风险评估
Derivation of predicted no-effect concentration(PNEC)and ecological risk assessment for perfluorinated and polyfluorinated compounds in soil and water environments
摘要
Abstract
Perfluorinated and polyfluorinated compounds(PFASs)have received widespread attention due to their environmental persistence and bioaccumulation.In this study,the species sensitivity distribution method(SSD),assessment factor method,and phase equilibrium partitioning method were used to derive the predicted no-effect concentration(PNEC)of PFASs in water environment and soil.Through the collection and analysis of data,an ecotoxicological database of 13 PFASs was established,and hazard assessment was carried out for the water environment and soil environment.In addition,the ecological risk assessment of water quality and soil in some areas of China was conducted by the risk quotient method.The results showed that the concentration of PFASs in most areas is lower than the PNEC value,indicating no unreasonable ecological risk.However,6:2 Cl-PFESA,as a substitute for PFASs,showed a high chronic ecological risk in some river basins,and PFHxA and PFOS also showed unreasonable ecological and environmental risks in the soil of some areas.Therefore,it was suggested that future research should strengthen environmental monitoring and risk management of such compounds,and at the same time explore more effective pollutant treatment technologies and safe substitutes to reduce environmental and health risks.关键词
