摘　　要：大气、植物间持久性有机物污染物(POPs)的交换行为是控制POPs进入食物链,及影响其全球范围内迁移、分布的重要环节.本文着重介绍了大气、植物间POPs交换过程方面的研究现状;总结了其影响因素,主要包括POPs本身的理化性质(lgKOA)、植物特性(叶片表面形态、脂质含量、表皮的可渗透性)以及环境温度;提出了目前大气、植物间POPs交换过程研究中存在的部分问题,以及今后可能的发展方向.Air-vegetation exchange of POPs is an important process controlling the entry of POPs into terrestrial food chains, and also has a significant effect on the global movement of these compounds. In this paper, the research status in the process of air-vegetation exchange of POPs was reviewed; Three main factors, including the physicochemical properties of POP compound （lgKoA）, variations of plants in surface morphology, lipid content and permeability of the cuticular skin, and environmental temperature that would result in the differences were summarized, the trends of future researches on air-vegetation exchanges of POPs were analyzed and prospected, and some possible research perspectives in the future were proposed.
