We analyzed the concentrations of polycyclic aromatic hydrocarbons (PAHs) in both particulate matter (PM) and the gaseous phase at 10 roadside sites in Hanoi, Vietnam. The average concentrations of 47 PAHs ( summation 47PAHs) were 63 +/- 82 ng m(-3) in PM and 480 +/- 300 ng m(-3) in the gaseous phase. The PAHs mainly originated from motorcycles without catalytic converters. The highest concentrations of summation 47PAHs in both PM and the gaseous phase were observed at a terminal for buses and trucks. The operation of large commercial vehicles led to increased PAH pollution at the terminal site.
我们分析了越南河内10个路边站点的颗粒物（PM）和气态相中多环芳烃（PAHs）的浓度。47种PAHs（∑47PAHs）在PM中的平均浓度为63±82 ng m⁻³，在气相中的平均浓度为480±300 ng m⁻³。PAHs主要源自没有催化转化器的摩托车。在一个公交和卡车终点站，PM和气态相中∑47PAHs的浓度均最高。大型商用车的运行导致该终点站的PAH污染加剧。
