Motor vehicle is the main sources of urban atmospheric particulate matter. Although the proportion of heavy vehicle in urban traffic is small, the emission concentration of particulate matter is generally more than 10 times higher than that of gasoline light vehicle, making a great contribution on total motor vehicle emissions. In order to make further study on motor vehicle emissions, our Prof. Lingyan He, Prof. Xiaofeng Huang and their students carried out observation experiment of air pollution in Tanglang Mountain Tunnel.

The experiment monitoring stations located on the left side of Tanglang Mountain Tunnel. It mainly analyzed VOCs, EC/OC in PM2.5, ions, heavy metals, the concentration of black carbon and non-refractory composition of PM1, in order to study the mechanism of tunnel air pollution.


The tunnel monitoring experiment need to take up the motorway, so they made declaration with transportation bureau and traffic police bureau in advance, and communicate with the tunnel station. In order to avoid traffic congestion, monitoring time was set as 24:00 to 6:00. During the period of monitoring, the driveway was sealled to ensure the staff safety and experiment go on smoothly. Tanglang Mountain Tunnel experiment has been completed successfully, and the samples are being analyzed at present.

The experiment got PM2.5 pollution condition under the certain composition and flow of motor vehicle by monitoring the concentration of vehicle emission pollutants and meteorological elements in the tunnel, and analyzed the pollution contribution of different models, which can provide data support for traffic emission reduction plan and the establishment of relevant control strategy.
