Passive sampling technique is an important supplementary tool in pollution monitoring. In recent years, samplers designed for the hydrophilic organic pollutants, including polar organic chemical integrative sampler (POCIS), Chemcatcher^®, and diffusive gradients in thin film technology (DGT), have been successfully applied in both laboratory experiments and field studies. This review gives an overview of the application of these passive samplers for monitoring the polar organic pollutants. Sampler structures, material compositions, and the calculation of time weighted average concentrations were also compared. Besides, difference of the three samplers on the scope of the target analytes and exposure time, as well as the effects of environmental factors, e.g. hydrodynamic conditions, temperature, pH, ionic strength, DOM, on sampling performance were also introduced.

被动采样技术是污染监测的重要补充工具。近年来，采样器专为亲水性有机污染物，包括极性有机化工综合采样器（POCIS），Chemcatcher ^®薄膜技术（DGT）中的扩散梯度已成功应用于实验室实验和现场研究。这篇综述概述了这些无源采样器在监测极性有机污染物中的应用。还比较了采样器的结构，材料成分和时间加权平均浓度的计算。此外，还介绍了三种采样器在目标分析物范围和暴露时间上的差异，以及环境因素，如流体动力学条件，温度，pH，离子强度，DOM等对采样性能的影响。
