摘　　要：极性有机化合物整合采样技术(Polar organic chemical integrative samplers,POCIS)适用于极性有机污染物的采集,随着新型极性有机污染物的不断出现,该技术已经引起了科学家的广泛关注.本文概述了几种常用的被动采样装置,重点介绍了POCIS采样器的一般结构、富集原理、环境因素如流速、温度、pH、溶解性有机质、盐度及膜的污染等对采样速率的影响,讨论了针对极性物质检测的质量控制和保证以及性能参考物质,综述了POCIS在水环境有机污染物监测中的应用.最后,本文对POCIS的应用前景进行了展望.Polar organic chemical integrative samplers （POCIS） are suitable for the sampling of polar organic pollutants in the aquatic environment. POCIS have evoked extensive attention recently with the occurrence of emerging polar organic pollutants. This review first overviewed the advantages and shortcomings of several popular passive sampling devices; and then focused on the basic structure, modeling and principles of sampling and effects of environmental factors including flow rate, temperature, pH, DOM, salinity and membrane fouling on the sampling rate （Rs ） of POCIS. Then quality assurance and quality control as well as performance reference compounds for polar organic compounds were discussed. The applications of POCIS in the monitoring of organic pollutants in the aquatic environment were reviewed. Finally, the prospect in this reseate.h fie.｜rt wn~ ,4~p A
