Воздействие передвижных источников на качество атмосферного воздуха городов

Development of road infrastructure causes of definition of exact structure of emissions of harmful substances from mobile sources of pollution, a contribution of each impurity to an overall picture of pollution of a ground layer of atmospheric air and specifics of dispersion. Sources of emissions of 17 names of metals, exhaust gases, abrasion of brake shoes and tires are, and the main contribution to pollution (on gross emissions) is made by vanadium, copper, zinc, antimony, manganese. The maximum volume of emissions is noted in an idling mode, during the braking and dispersal. In connection with existential, organizational and so forth difficulties of realization of experimental environmental monitoring of quality of atmospheric air in areas of coverage of highways for definition of deposits of a motor transportation component in formed level of pollution generally use now settlement methods.
