New Investigations of Exhaust Gas Emissions of Motor Vehicle Traffic

In the scope of efforts at air purification, a registration system has been developed on behalf of the Ministry of Labor, Health, and Social Affairs of North-Rhine-Westfalia considering every kind of emission contributing to air pollution. The emissions of motor vehicle traffic, industry, small business and domestic furnaces are registered. The system establishes data with regard to place, time, duration, quantity, type, condition, and temperature of the emissions. The present state of investigation regarding motor vehicle traffic is discussed in this paper for the area of Cologne, West Germany.
