[摘要]：通过厦门市仙岳隧道实验建立了厦门市机动车尾气源饱和烃( 正构烷烃、甾萜类化合物等) 及多环芳烃等主要烃类污染物的特征排放谱, 得出厦门市隧道尾气PM10 中PAHs 的苯并[ a ] 芘等效毒性(BEQ) ( 3. 99) 约为厦门城市大气的2. 5 倍, 对人体健康威胁更大. 同时估算出汽油车和柴油车对厦门大气机动车尾气排放PAHs 的贡献率分别约为70%和30%.[Abstract]:Tunnel study was carried out in Xianyue tunnel in Xiamen city to characterizethe emission of saturated hydrocarbons and polycyclic aromatic hydrocarbons ( PAHs) fromvehicles. The contents and the profiles of these pollutants were given in this paper. T hevalue of BEQ of PAHs in Xianyue tunnel air was 3. 99, which was about 2. 5 times that inXiamen City which brought higher threat to human health. Results showed the contributionsof emission from gasoline-engined vehicles and diesel-engined vehicles to the PAHs inXiamen city air have been quantified to be about 70% and 30%.
