| 摘 要： | 通过比值法、因子分析法和多元逐步回归模型对南京市交通干道区颗粒物中的多环芳烃的源解析进行研究。结果表明南京市交通干道区颗粒物中多环芳烃的主要污染源是燃煤源、汽油燃烧排放源和柴油燃烧排放源 ,它们对多环芳烃的贡献率分别为 45 .2 %、34 .0 %和 2 0 .7%

| Abstract: | Ratio method, factor analysis method and multiple regression model were applied to source apportionment experiment of polycyclic aromatic hydrocarbons (PAHs) in airborne particulate at traffic areas in Nanjing. Results showed the PAHs in all samples from traffic trunks were strongly associated with the emission of coal combustion, gasoline emission and diesel emission, which accounted for 45.2%, 34.0% and 20.7% of total PAHs respectively. |
