Abstract. Subject of the study is a process of emission dispersion and formation of zones with air polluted by emissions from the mining-and-processing plant and motorway in the areas near the city. Objective of the work is creation of information system for assessing level of air pollution in the territory where these sources of impurities are available, and assess of risks of chronic intoxication of population. The created mathematical model is based on the solution of three-dimensional equations for transportation of impurities coming directly from the permanently operating stationary source (mining and processing plant) and from linearly distributed source (motorway). The numerical model is based on the splitting of model equations and their solving by the implicit difference scheme. As a result, software was created, which made it possible to carry out computational experiments on the calculation of zones with atmospheric air polluted by carbon monoxide with taking into account interference of impurities coming from various types of pollution sources, and with taking into account different meteorological parameters. On the basis of the obtained field of concentration, the changed risk of chronic toxicity associated with atmospheric air pollution by carbon monoxide was assessed for the 10-year period. The obtained patterns of impurity dispersion based on interference of emissions and calculation of intoxication risks allow to solve problems of assessing level of environmental hazards, and to make reasonable management decisions on the priority of implementing environmental protection measures and preventive measures for protecting the population.
Keywords: mining-and-processing plant, motorway, dispersion of impurities, calculation of intoxication risks, numerical model.
