摘要
近年来,全氟和多氟烷基化合物(PFASs)在全球范围内受到广泛关注,其在多种环境介质中均有不同程度检出。其中,土壤既是PFASs污染的重要受体,也会在吸附-解吸、淋溶等作用影响下成为释放PFASs的污染源,从而对受纳水体造成持续污染,尤其是对土壤下覆地下水系统的影响持久而深远。因此,理解PFASs在土壤-地下水系统中的迁移转化过程是预测其环境归趋和风险控制的重要任务。文中总结了近年来国内外的相关研究,对土壤-地下水系统中PFASs的污染来源和界面行为进行了综述,并对现存问题和未来需求进行了展望,以期为PFASs在土壤-地下水系统的监测与控制提供参考和支撑。
In recent years,perfluro and polyfluoroalkyl substances(PFASs)have received widespread attention globally,and they have been detected to varying degrees in various environmental media.Among them,soil is not only an important receptor of PFASs pollution,but also becomes a source of pollution that releases PFASs under the effects of adsorption-desorption,leaching,and other processes,which will cause continuous pollution on the water body,especially the long-lasting and far-reaching impact on the groundwater system under the soil.Therefore,understanding the migration and transformation process of PFASs in soil-groundwater system is an important task for predicting their environmental fate and risk control.This article summarizes relevant research both domestically and internationally in recent years,reviews the pollution sources and interface behaviors of PFASs in soil-groundwater systems,and looks forward to existing problems and future demand,in order to provide reference and support for the monitoring and control of PFASs in the soil-groundwater system.
