| 摘 要： | 采用固相吸附－热脱附－色谱／质谱检测器联用的方法分析了广州市街道空气中的发挥有机物。样品采自广州市区街道的３２个采样点，主要探讨了其中单环芳烃和正构烷烃的特征和可能来源；选取１３种烃类化合物进行进一步的因子分析，结果表明，这些挥发烃类可能主要来自汽油机车、工业和柴油机车的排放。多元线性回归分析表明３种源对所选挥发烃类的平均贡献分别为６４％、２３％和１３％。

| Abstract: | Airborne volatile hydrocarbons in Guangzhou streets were analysed by sorbent tubethermodesorptionGC/MSD method in this studySamples were collected at 32 various street sites in Guangzhou,and the charateristics and possible sources of monocyclic aromatics and normal alkanes were investigatedBy using factor analysis on 13 hydrocarbons,the sources of volatile hydrocarbons in Guangzhou were further identified,namely gasoline traffic,industry and diesel trafficThe results by multiple linear regression indicated that the percentage of volatile hydrocarbon contributions by these sources is 64%(gasoline traffic),23%(industry),13%(diesel traffic)respectively |
