| 中文摘要: |
| 2014年12月采集南京市玄武湖隧道内不同点位、不同行驶工况及加油站环境中VOCs样品，比较隧道内不同测点、拥堵与非拥堵、隧道环境与燃油挥发样品VOCs浓度、组分及特征污染物的变化情况。结果表明，隧道样品中106种目标化合物全部检出；拥堵情况下VOCs体积分数较非拥堵情况下升高了7.4倍；加油站环境和隧道环境的VOCs组分中烷烃、烯烃和芳烃存在显著差异。 |
| 英文摘要: |
| A survey on VOCs in Nanjing Xuanwu Lake Tunnel was conducted based on the determination in different sites and different driving conditions in the tunnel, and the emissions from gas stations in December 2014. Comparing the concentration， composition and variation of VOCs in different sites, traffic congestion or not, and the gas station environment, the results showed that 106 target compounds were detected. The VOCs concentration in traffic congestion was 7.4 times as much as that in non congestion. Among the VOCs components, alkanes, olefins and aromatics showed significant difference between gas station environment and tunnel environment. |
