| 摘 要： | 利用气相色谱法对交通路口机动车排放的挥发性有机化合物(VOCs)进行了监测,讨论了交通路口大气中VOCs的浓度水平和排放特征,并将历年来的数据进行了对比,结果表明,由于汽车保有量的增加,VOCs浓度有增加的趋势.使用无铅汽油后,烷烃、烯烃、芳香烃的组成比例有所变化,芳香烃的含量有较大程度的增加.

| Abstract: | The situation of volatile organic compounds emitted from motor vehicle in traffic crossing were monitored with GC; the concentration level and the emission characteristics of VOCs in the air was discussed; and the data of past years were compared. The results indicated that the concentrations of VOCs tended to increase because of the increased vehicle population. After using the gasoline without lead, the composition ratios of alkane, alkene and aromatic hydrocarbons changed to same extent; and the aromatic hydrocarbons content increased in rather high degree. |
