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 1 1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。
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.
