ABSTRACT
The article is devoted to the study of pollutant distribution in the atmosphere of Irkutsk. These pollutants enter the air basin from industrial enterprises and vehicles. Irkutsk is a big industrial centre of Siberian federal district of Russian Federation. On the grounds of the city there are approximately 250 industrial enterprises with more than 3 000 stationary air pollution sources carried as an asset and more than 200 000 vehicles. Air pollution was estimated by the multivariate statistical analysis and the numerically simulated model based on analytic calculations of differential equation of travel and eddy mixing extraneous substances. Inventory data for indicators of emitters, vehicle data and remote sensing data together with long-standing data of wind velocity and air temperature daily weather observations with 8-prefix of time were applied as the input information. Special attention has been paid to climatic features of the area, as the city is located in an area with low self-purification potential of the atmosphere. By results of research the authors carried out zoning of the city, identified the areas with the highest level of pollution based on distribution of emissions from stationary and mobile sources and analysis of the accumulation of pollutants in the snow cover.
