Characteristics and Sources of Atmospheric Volatile Hydrocarbons in Guangzhou Streets
广州街道空气中挥发烃类特征和来源分析

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
