以老工业区大气中有机污染物为研究对象,采用预浓缩-GC/MS方法分析了老工业区大气中挥发性有机物（VOCs）的分布和组成特征。结果表明,老工业区内工业行业的复杂性和规划的不合理性,导致有机物分布和组成的差异。混杂区和工业集中区VOCs的浓度大于居住区和对照区,并且有机物的浓度存在垂直分布规律。卤代烃是老工业区大气中含量最高的挥发性有机物,占TVOC的27%,其次是饱和烷烃和芳烃,分别占TVOC的21%和20%。
以老工業區大氣中有機汙染物為研究對象,採用預濃縮-GC/MS方法分析瞭老工業區大氣中揮髮性有機物（VOCs）的分佈和組成特徵。結果錶明,老工業區內工業行業的複雜性和規劃的不閤理性,導緻有機物分佈和組成的差異。混雜區和工業集中區VOCs的濃度大于居住區和對照區,併且有機物的濃度存在垂直分佈規律。滷代烴是老工業區大氣中含量最高的揮髮性有機物,佔TVOC的27%,其次是飽和烷烴和芳烴,分彆佔TVOC的21%和20%。

Taking the atmospheric organic pollutants of old industrial areas as research object,distribution and composition of ambient volatile organic compounds（VOCs）in old industry city was analyzed by using the method of pre-concentration GC-MS.The results show that the industrial complexity and unreasonable planning lead to different organics distribution and composition in old industrial city.The concentration of VOCs in industrial zone and the mixed areas are greater than that in residential areas and controlled areas of the old industry city.The VOCs concentration reduced vertically.The major components were halogenoalkane,saturated alkane and arene,which accounted for 27%,21% and 20%,respectively.
