| 摘 要： | 用热解析气相色谱法采集分析不同动力公交车微环境中苯系物,研究了江南某旅游城市公交汽油车、柴油车、电车、液化天然气车、油电混合车空气中苯系物的浓度以及主要公交站台的苯系物的浓度。结果表明,公交车微环境中苯系物平均浓度从高到低依次为汽油车>柴油车>油电混合车>液化天然气车>电车,其中汽油车苯含量最高,为(21.02±9.51)μg/m3,各动力公交车的苯暴露对公交司机致癌风险为2.32×10-6～4.79×10-6,超过了美国EPA制定的人体致癌风险限值。

| Abstract: | The concentration of BTEX in the air of the main bus stops and buses driven by gasoline,diesel,electricity,liquefied nature gas(LNS) and gas-electricity mixture in the city were investigated using thermal desorption with gas chromatography.BTEX in mobile microenvironment showed in the order gasoline-motor car>diesel-motor car>gas-electricity mixture-motor car>LNS-motor car>electricity-motor car.BTEX occurred most in gasoline-motor car and the concentration is(21.02±9.51)μg/m3 and the carcinogenic risk of benzene is varied from 2.32×10-6 to 4.79×10-6 in different kind of buses and all of them are higher than the limit set by USEPA. |
