In the article, the groups of parameters of the properties of dust aerosol released into the air pool at the clay and sand transshipment sites of the construction industry, in particular at brick factories, are investigated. The main type of pollutant in the article is considered inorganic dust containing 70-20% silica. The properties of a dust aerosol are presented from the standpoint of the theory of stability of dispersed systems. The main classification feature in the distribution of the parameters of the properties of the groups selected physical nature of the processes and phenomena observed in the dust aerosol. As a result of the construction of a physical model of the process of air pollution, a detailed analysis of the objects involved in the pollution process was conducted.

The article presents the physical essence of the method of hydrodynamic reduction of air pollution by foam method as the most effective technology palisadian open for extended sources. The mathematical description taking into account the physico-chemical properties of dust and a bubble of foam, and the parameters of the return to technological raw materials dust particles due to the different physical mechanisms of their capture. Parametric dependence of the efficiency of dust removal as a result of setting foaming method of palisadian provides the ability to forecast its calculation for the considered technology implementation process palisadian air bearing features of the interaction of dust with a layer of foam.

The article presents a mathematical description of efficiency of process of spray foam dust suppression on conveyor belts construction businesses. The obtained parametric dependence of the efficiency of dust suppression as a result of setting way foam dust control will provide a predictive calculation of the technological parameters of the process of dust control with consideration of the peculiarities of the interaction of dust aerosols with bubbles of foam, and can also be used as a predictive criterion for the sanitary-hygienic and ecological evaluation of the selected technology for dust control.

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.

Considered relevant for the construction industry the problem of air pollution by dust. A significant level of airborne dust is typical for plants of concrete products and structures. A physical model of the process of mixing of air pollution department, which includes the main stage of the contamination: education, allocation and distribution of pollutants. Ustanovnleno that the main objects of the physical model are contaminant technological raw materials, manufacturing equipment, the workplace air and the ground layer of the atmosphere.
