| 摘 要： | 文章应用苏码罐采样,预浓缩系统与GC-MS联用测定环境空气中39种挥发性有机物,结果表明淮安空气中以苯系物浓度较高,范围为4.80~59.68μg/m3,以甲苯和苯浓度最高;VOCs浓度范围为5.88~66.50μg/m3;空气中甲苯浓度高于苯,说明其主要来源于汽车尾气。

| Abstract: | Pre-concentrated system combined GC-MS was evaluated for determination of 39 kinds of trace volatile organic compounds（VOCs） in ambient air using SUMMA canister for sampling.The major components were BTEX with concentration of 4.80 ？g/m3 to 59.68 ？g/m3,while the concentration of VOCs was 5.88 ？g/m3 to 66.50 ？g/m3.Concentration of toluene was higher than benzene,because of the main source is the discharge of tail gas of vehicles. |
