持久性有机污染物土气交换过程及采样技术的研究进展

摘要

Persistent Organic Pollutants (POPs) disperse and finally approach equilibrium among multi-media in environment according to portioning rules,and this kind of equilibrium will be affected by physical-chemical parameters,meteorological conditions,vegetarian of soil surface and so on.The air-soil exchange of POPs will control the environmental fate among different environment media,and provide supporting information for risk assessment of human beings,flora and fauna.This review summarized the processes and techniques of air-soil exchange of POPs,serving as reference to future study.%持久性有机污染物在多元环境介质中按一定规律分配并趋于平衡,且平衡过程受理化参数、气象条件及地表植被等影响.持久性有机污染物土气交换是控制其在环境介质中迁移分配的重要过程,也是衡量人类和其他动植物暴露其中风险的基础.对持久性有机污染物的土气交换过程及其采样技术进行总结,希望对其后期研究提供参考.
