摘　　要：介绍了大气中半挥发性有机污染物的采样方法和气/固相分配模型,综述了索氏提取、超声波萃取、超临界流体萃取、微波萃取、固相微萃取等样品预处理方法,以及直接进样热解析和其他仪器分析方法,对大气中半挥发性有机污染物的监测研究进展作了展望。It reviewed the development of sampling, gas/solid partition model and analysis methods for semivolatile organic compounds (SVOCs) in recent years. It focused on comparing the sampling artifacts of high volume and diffusion denuder samplers. It also lined main pretreatment methods: Soxhlet extraction, supersonic extraction , supercritical fluid extraction, microwave assistant extraction, and solid phase micro extraction. In addition it discussed the comparison between these methods and the direct sample introduction thermal desorption methods.
