中文摘要：

大气中持久性有机污染物（POPs）的气（气相）-粒（颗粒相）分配是影响POPs在大气中分布、迁移和转化的一个重要因素,研究POPs的气-粒分配特征有助于提高POPs环境归趋预测的准确性,对区域范围内的大气POPs污染防治具有重要意义.本文简要介绍了两种经典的POPs气-粒分配理论及模型,总结了有关大气中几类典型POPs在气相和颗粒相中的分配特征研究的最新进展,讨论了不同种类POPs气-粒分配的一些差异性特征和可能的影响因素,并提出了大气中新型POPs气-粒分配特征研究中亟待解决的问题.

英文摘要：

Gas /particle partitioning of persistent organic pollutants（ POPs） is an essential factor that affects the distribution,transport and transformation of POPs in the atmosphere. The investigation of the gas /particle partitioning of POPs in atmosphere could help improve the accuracy in predicting the fate of POPs and control the regional POPs contamination in the atmosphere. In this study,two classical models for the prediction of POPs gas /particle partitioning were briefly described. The latest progress about the distribution of some typical POPs in the gas phase and particle phase weresummarized. In addition,the characteristics and possible influence factors of different POPs were discussed,and some issues that need to be solved in the future study were proposed.
