As a major source of air pollution in urban areas, the motor vehicle exhaust has attracted more and more attention due to its growing amount and serious harm to human health. It is of benefit to the pollutant control to make clear the transportation characteristics of vehicle exhausts. In this paper, the transportation characteristics of vehicle exhaust pollutants are investigated by means of the on-site measurement based on a typical Beijing expressway-Badaling expressway (G6 state expressway). The concentrations of CO, NOx, S02 and particles near the expressway were obtained, by which the variations of the particle num- ber and mass concentrations, as well as the gas pollutant volume concentrations in the vicinity of the roadways with the dis- tance from the expressway were fitted. The results show that the gas pollutant concentrations and particle concentrations de- crease almost exponentially with the distance from the expressway, which is helpful for the air pollutant database establish- ment and future pollution control in big cities. 展开更多
