摘　　要：被动采样器在许多工作场所中发挥着重要的作用,与主动采样器相比,具有易便携、质量轻、操作简便且不需要电力或采集动力等优势。被动采样器是采集一段时间内的气体污染物并进行浓度测定,即时间加权平均值(TWA)浓度。被动采样器主要用于监测大气中的污染物,但对土壤中挥发性有机物的监测比较少用。主要介绍了被动式采样器国内外的研究现状、类型原理及性能要求,综述了被动采样器中吸附剂种类及其效果,并介绍了被动采样器近些年在土壤中挥发有机物测定中的研究现状,最后对被动采样器的未来前景进行了展望。Passive samplers play an important role in many workplaces and have advantages of easy to carry,lightweight,easy to operate and no needing electricity or gathering power compared with active sampling.Passive samplers collect the concentration of gaseous pollutants over a period of time,known as the time-weighted average（ TWA）concentration.Passive sampler is mainly used to monitor the pollutants in the atmosphere but has hardly been used in monitoring pollutants in the soil. This paper introduces mainly the research status,type principle and performance requirements of passive samplers at home and abroad,describes the types of adsorbents in passive samplers and their effect,and introduces the research situation using passive sampler to monitor VOCs in soil in recent years. Finally,the future prospects of passive samplers are prospected.
