Considers the most important sources of material pollution of urban territories. A comprehensive approach to studying properties of pollutants, based on the theory of disperse systems. Built block diagram of systematization of parameters that determine the behavior of contaminants from the position of theory of disperse systems. The dependence between the behavior of pollutant aerosol and parameters of its stability.
Keywords: Contaminant dispersion system, the parameters of pollutant properties, stability of pollutant aerosol
