摘要
综述了全氟和多氟烷基化合物(PFASs)在国内外地表水环境中的空间分布及污染特征,总结归纳了PFASs的来源和特征变化趋势。针对地表水中PFASs的监测种类、监测技术及风险评估等方面存在的问题,提出未来需加强日常监测,重点加强对水环境中新型PFASs的关注;针对流域中不同种类PFASs建立高特异性、高灵敏度监测新技术;筛选适合的水生生物作为环境污染指示物以应用于新污染物的评估等建议。为今后我国地表水环境PFASs污染的现状调查及治理工作提供确实可行的科学参考。
The spatial distribution and pollution characteristics of Perfluoroalkyl and Poly-fluoroalkylated substances(PFASs)in the surface water environment at home and abroad are reviewed,and the sources and characteristics of PFASs are summarized.Aiming at the problems existing in the monitoring types,monitoring technologies and risk assessment of PFASs in surface water,suggestions are put forward on strengthening regular monitoring with strong focus on emerging PFASs,establishing new technologies with high specificity and high sensitivity,and screening suitable aquatic lives as environmental pollution indicators for assessment of emerging pollutants.It provides a feasible scientific reference for the investigation and remediation of the current situation of PFASs pollution in our country's surface water environment in the future.
