MOTOR TRAFFIC, A SOURCE OF POLLUTION

TRAFIKEN SOM FOERORENINGSKAELLA

This study deals with air pollution in towns where the car is the main source of pollution. In Stockholm the motor traffic is responsible for over 90% of the hydrocarbon and at least 75% of the dust pollution at street-level. In the model town of 200000 inhabitants the cars are estimated to be responsible for 90% of the dust at street-level during winter while oil heating is responsible for 5%. The corresponding figures above roof-level in the heart of town are 50% from cars and 30% from oil heating. The author discusses particle-bound hydrocarbon as well as the importance of the fuel aroma regarding polyaromatic hydrocarbon (pah) emission and nitrosubstituted pah. In a town of 200000 inhabitants the motor traffic is responsible for 99% of the lead emissions. Chemical emissions as a consequence of used fuel additives are considered as well as gaseous emissions from cars and the different types of chemical emission from methanol and diesel driven vehicles. The author summarizes recently published reports to support his study. /TRRL/
