| 基于江苏省2009年—2014年不同类型机动车保有量统计数据，采用不同车型排放因子法构建江苏省不同年际汽车尾气多环芳烃排放清单。结果表明:汽车尾气多环芳烃排放总量分别为138.97 t、167.27 t、194.65 t、215.55 t、239.24 t和274.04 t，呈现出逐年增加的趋势。其中，重型货车、轻型和小型汽车对多环芳烃的贡献比例在逐年增大，而中型、大型客车及中型货车对城市PAHs的贡献率在逐年减小。重型货车对2-3环多环芳烃的贡献比例是最大的。中型和大型客车对4-6环多环芳烃的贡献比例最小。 |

| Based on the statistics of different types of vehicles released by Jiangsu province from 2009—2014, different Emission Factors of various vehicle is adopted to build different PAHs Emission list of the vehicle exhaust in different years in Jiangsu province. It turns out that the emission amount of the PAHs exhaust in Jiangsu province from 2009—2014 is respectively 138. 97, 167. 27, 194. 65, 215. 55, 239. 24 and 274. 04tons, which shows a trend of increasing year by year. Among the statistic, the contribution ratio to PAHs of heavy truck, light and small vehicles are increasing with years. While the contribution ratio of medium and large coaches and medium trucks to the city PAHs is reducing with years. The contribution ratio of heavy trucks to 2-3 PAHs is the highest among all the vehicles. While the contribution ratio of medium and large coaches to 4-6 PAHs is the lowest. |
