By air pollution we usually mean the presence of a certain concentration of gaseous and particulate pollutants in the atmosphere. A stationary or point source of air pollution is a non-moving source of pollutant emissions, such as an industrial plant. The speed of spreading pollution from a point source is a decisive parameter when we talk about the impact of pollution on natural resources or built objects, but the most important is its impact on human health. Modeling the process of air pollutant dispersion is an important engineering tool in researching the impact of pollution on the natural environment. The analytical solution of the transport two-dimensional gradient equation of advective-turbulent diffusion in the stationary state is presented. The derived equations represent the dependence of diffusion coefficients and wind speed as a complex function of the distance from the ground surface. This model is suitable for accurately predicting the level of concentration of emitted pollutants near the source as well as further downwind, under neutral or stable atmospheric conditions. The parameters necessary for specific calculations are adopted from literature data. The results obtained in this way were compared with the results obtained using the Gaussian dispersion model.
