摘要:
通过对天津市内的几个典型地区大气颗粒物进行测定,检测出58种多环芳烃,并对11种多环芳烃进行定量测定。其结果表明,所涉及 的区域在采暖期内大多数点位的苯并(a)芘超标,超标倍数在1.1~4.6之间;交通繁忙地区的多环芳烃的污染程度高于其他地区;笔者还对多 环芳烃在不同粒径颗粒物上的分布特征、苯并(a)芘与大气颗粒物进行相关性分析和评价。

Study on the EHstribution of Polycyclic Aromatic Hydrocarbons on the Atmospheric Particulates in the Part of Tianjin
SUN Ren,ZHU Tan
Abstract:
The atmospheric particulates in typical areas in Tianjin were measured.58 kinds of PAHs are determined and 11 kinds of them were analyzed quantitatively . The result showed that benzo(a) pyrene concentration was mostly above the national ambient air quality standard during the heating season , with the exceeding rate of 1.1~4.6. The pollution level in heavy traffic areas was higher than that in other areas . The distribution of PAHs on various diameters of atmospheric particulates ,and the correlation between benzo (a)pyrene and TSP or the other PAHs were analyzed and assessed.
