摘要
随着《斯德哥尔摩公约》的实施,大气中持久性有机污染物(POPs)的大气被动采样(PAS)观测技术得到了快速发展,相比于传统大气主动采样技术,PAS技术具有明显的优势。以应用最为广泛的聚氨酯软性泡沫材料大气被动采样(PUF-PAS)为例,重点阐述和讨论了3种通过大气被动采样技术来计算污染物在空气中的浓度的方法,并对其采样原理和发展趋势进行了简要介绍。
With the implementation of Stockholm Convention,passive atmospheric sampling（PAS） techniques for persistent organic pollutants（POPs） monitoring have been greatly developed and improved.PAS has shown its convenience and advantages by compare with the conventional active sampling technology.The review takes the most popularly used PAS,the polyurethane foam based PAS（PUF-PAS） as an example.It is focused on 3 kinds of methods for atmospheric concentrations of POPs derived from PAS.The sampling theory and prospect of PAS have also been discussed.
