植物叶面吸收有机污染物机理研究进展OA北大核心

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.
