摘　　要：本文通过文献梳理,分析了全(多)氟烷基化合物(PFAS)对植物的暴露途径;统计了已发表文献中36种植物对19种PFAS的转运、富集特征;系统地阐释了PFAS从环境介质到植物组织内的迁移、积累机制;讨论了PFAS分子结构(如全氟碳链长度、头部官能团)、植物生理特性、环境因素对该富集过程的影响,并提出了未来有关植物富集PFAS可关注的重点和方向,以期能深入认识PFAS在环境介质-植物根际-植物组织内的赋存与迁移转化特征,更好地管控评估PFAS污染场地并制定植物修复方案,为开展生态与健康风险评价提供参考.This review summarized the literature data,including bioaccumulation of 19 kinds of per-and polyfluoroalkyl compounds(PFAS)by 36 plants.Exposure,transport,and bioaccumulation feature data are summarized and interpreted;the mechanism of migration and accumulation of PFAS from environmental media to plant tissues was systematically elucidated;effects of PFAS molecular structure(such as perfluorocarbon chain length and head functional group),plant physiological characteristics,and environmental factors on the bioaccumulation process were discussed.In addition,future studies of phytoremediation and combined remediation of PFAS contaminated sites were prospected.The information can be used to manage and evaluate PFAS-contaminated sites,formulate phytoremediation plans,and assess ecological and health risk of PFAS contaminated sites.
