Abstract: This work considers the actual problem related to solving the problem of forecasting and environmental monitoring of air pool of industrial regions, where there is an imbalance of sanitary environmental standards due to the large number of emissions of harmful substances and active fine aerosol particles, and carbon dioxide gases into the atmosphere. In the article for solving the above mentioned problem there is a full mathematical model developed to conduct a comprehensive study of the process of transfer and diffusion of pollutants released into the environment from production facilities, which is described by a system of differential equations in partial derivatives with appropriate initial and boundary conditions. To derive a mathematical model of the object there were used the basic laws of mechanics and hydro thermodynamic (conservation equations of mass, energy, balance of power, the state, etc..), Taking into account the main parameters that play a significant role in the process of transport and diffusion of pollutants in the atmosphere: the wind speed and its directions; terrain; absorption coefficient of harmful aerosol fine particles in the atmosphere, etc. We obtain the differential equation for calculating the rate of deposition of fine and aerosol particles, propagating in the boundary layer of the atmosphere, when the principal parameters are considered, which affect the rate of particle deposition: the mass and radius of aerosol particles, density of the atmosphere, air resistance force.
Key words: mathematical model, transfer and diffusion of pollutants, climatic factor, mechanics, hydro thermodynamics.
