The Determination of Auto Transport Impact on Urban Agglomerations. Monitoring air quality in urban agglomerations of the Republic of Moldova shows an increased level of atmospheric air pollution in some areas exceeding several times the sanitary level. The air quality was determined by direct measurements of concentrations in air polluting substances, using standard methods, by calculating the quality and quantity of used fuels. To determine the contribution to the pollution sources of pollution and the assessment rate to the fund of transport auto pollution, the rate impact of motor transport, and from fixed sources of pollution in the investigated areas, were inventoried fixed sources of air pollution, determined the intensity of road traffic, and transport structure. The emissions of polluting substances from fixed sources were determined by inventory. The evaluation of impact and pollution sources on atmospheric air quality was conducted on the basis of inventory data, LAE normatives (limited allowable emissions) and MAC (maximum allowable concentrations).
