The problem of integrated accounting of environmental factors to ensure the environmental safety of urban complexes is currently not fully resolved. To solve it, we propose to consider the factors of theurban environment at three main territorial levels: macro level, meso level and micro level. At the same time, those that are most important for the integrated consideration of environmental factors to ensure environmental safety at a specific level should be separately identified. In our opinion, further research in this direction should be based on the correct identification and detailed consideration of factors affecting the urban environment, followed by an assessment of impact levels. According to the results of the research stage, it can be concluded that the achievement of the environmental safety of theurban-planning territorial complexes is possible only with the improvement of the existing scientific and methodological base in the field of preliminary assessment of the level of environmental impacts andthe selection of appropriate measures. Undoubtedly, such an approach can bring closer the achievement of the global goal in the field of sustainable urban development, making a comprehensive assessment ofthe environmental impact of influencing factors more informative and accurate.

The aim of research is to develop a methodology for assessing the properties and behavioral characteristics of toxic pollutants, that will allow to examine the nature of the change of stability, controlling it. We systematized property parameters and energy parameters of pollutants, investigated characteristics of their behavior in the conditions of urboecosystem. We proposed a method that allows to assess the behavior of the aerosol stability, controlling the behavior of toxic pollutants in order to reduce their stability and, ultimately, to reduce air pollution.

Abstract.The article provides the analysis of the physical essence and simulation of the process of dust retention with foam in the air of working zones of belt conveyors transporting sand, crushed stone, gravel, coal, grain. In accordance with the proposed physical-energy concept of simulation of the process of dust control its physical essence is in a deliberate sequential action on the dust particles with previously prepared by the parameters external (additional) dispersed systems. Use of dust retention technology foam method provides high efficiency of reducing the concentration of dust in the air of working areas of belt conveyors, which varies in the range of 85.0-99.0 %, which provides the standard level of dust contamination (MPC) in air of working areas of listed industrial sources of formation and emission of dust.
