This study investigates the PM emission and analyses the PAHs content in PM emitted from gasoline-fueled vehicles. Outflow from the vehicles appear to be the ultimate source of PAHs in metro urban communities since the emission from gasoline vehicle increases the wellbeing hazard due to contiguity of exposure to gasoline exhaust. In this study, fifteen vehicles were randomly taken for sampling, where sixteen priority PAHs concentration were investigated. The study was performed on the vehicles with different Euro standard emission by taking into consideration the European legislative levels for vehicles on the toxic gaseous emission. Among all the PAHs outflow components of PM radiated in the exhaust of gasoline engines, the average concentration of total PAHs discharged was 0.377ng/L-fuel, while the total BaPeq concentration was 0.00993ng/L-fuel.
本研究调查了 PM 排放，并分析了汽油燃料车辆排放的 PM 中的多环芳烃含量。由于接触汽油尾气的临近性，车辆排放似乎是城市地铁社区中多环芳烃的最终来源，因为汽油车辆的排放增加了健康危害。在本研究中，随机抽取了 15 辆车进行采样，调查了 16 种优先多环芳烃的浓度。这项研究是在考虑到车辆有毒气体排放的欧洲立法水平的情况下，对不同欧洲排放标准的车辆进行的。在汽油发动机尾气中排放的 PM 所包含的所有多环芳烃逸出成分中，总多环芳烃的平均排放浓度为 0.377ng/L-燃料，而总 BaPeq 浓度为 0.00993ng/L-燃料。
