摘要
该此研究分别于5月和8月在广州市主要的交通干道进行空气样品采集,并运用吹扫-捕集GC-MSD系统对其进行定性和定量分析。文章对样品中的四氯化碳、三氯乙烯和四氯乙烯等卤代烃化合物在街道微环境中的浓度水平;化合物含量的月、周末与非周末、上午与下午等的时间变化和新旧城区的空间分布特征进行了探讨。
Halocarbons were one of the major pollutants in urban atmosphere, being adverse effects on human health and ambient ozone, In this study, air samples were collected in urban Guangzhou streets respectively in May and August, and analyzed by a system of PurgeTrap/GC-MSD, This study discussed the characteristics of carbon tetrachloride, trichloroethylene and tetrachloroethylene in urban Guangzhou streets, and the comparisons of their concentrations respectively between May and August, between weekend and weekdays, between morning and afternoon and between old and new urban streets.
