摘　　要：用吹扫 捕集/气质联用方法对北京市近郊四个典型地区土壤中VOCs进行分析.共检出11个目标挥发性有机物和49个非目标化合物,主要为苯系物、正构烷烃、挥发性氯代烃等,其中包括7种EPA优先控制有机化合物.The compositions of VOCs in soils from Beijing suburban were identified and quantified by purge-and-trap gas chromatography/mass spectrometry methods. 60 VOCs in total were detected in the four typical soil samples. The major pollutants were benzene-substituted, n-alkanes, and chlorinated hydrocarbons. Among them, 7 compounds were listed on EPA priority pollutants.
