摘　　要：植物是有机污染物的重要储存体。有机污染物可以跨叶面进入植物体,并通过食物链的富集作用,造成潜在的环境和健康风险。气孔和角质层是叶面吸收有机污染物的两个主要途径,角质层作为典型的大气-植物体微界面,是植物和大气中有机污染物的双向运输障碍。相对于气孔的直接吸收,有机污染物在角质层上的跨膜行为更加复杂。本文总结了有机污染物的叶面吸收途径,综述了有机污染物的叶面吸收机理及影响因素,重点阐述了有机污染物跨角质层的运输过程,并展望了未来的研究趋势和发展方向,为更好地了解有机污染物的叶面吸收机理及其在环境中的归趋行为提供理论基础。Plants play a crucial role as reservoirs of organic pollutants.Organic pollutants can be absorbed by plant leaves and accumulate within the plants,thereby posing potential risks to both the environment and human health as they move up in the food chain.Stomata and cuticle are the two main pathways for foliar uptake.The cuticle,as a key interface between the atmosphere and plants,serves as a bidirectional barrier for the transportation of organic pollutants.In comparison to direct stomatal uptake,the transcuticlar behavior of organic pollutants is notably complex.This article provides a comprehensive overview of the foliar uptake pathways of organic pollutants,explores the mechanisms and associated factors involved in their penetration of leaf surfaces,and outlines future research directions.It is anticipated that this review will establish a theoretical foundation for enhancing our understanding of foliar uptake mechanisms and the fate of organic pollutants across various environmental matrices.
