Transportation and Pollution

The pollutants of vehicle emission will cause environmental pollution along the traffic artery, producing photochemical smog. When the vehicles are close, one car’s exhaust pipe just in front of the next vehicle’s air inlet, large amount of pollutants will come into the car from the ventilation system of the car, this becomes one of the main sources of the vehicle air pollution. Therefore, this paper investigated the formaldehyde concentration of the Hangzhou Ling’an City typical traffic microenvironment (including buses, taxis, and bus stations, etc.) and traffic artery. Based on the quantitative health risk analysis, this paper provided basic data for formaldehyde pollution in transportation microenvironment analysis and health risk assessment.
