Air pollution in residential areas near industrial plants is one of the most significant problems of modern ecology. The resulting dust is one of the important factors in assessing the adverse impact on the environment. Studies show that the greatest danger to the human body is particles up to 10 microns in size. When analyzing the dispersion of dust in the residential and industrial areas, it is possible to estimate the percentage of particles PM10 and PM2.5 from the total amount that is necessary to effectively control the effects of dust on human health. The article gives a comparative analysis of the results of studies of the dispersion composition and dust concentration in the air of the working zone and the urban environment.

The paper proposes a new foam based on cement and the steelmaking slag, which is obtained and developed at the Department of construction materials and special technologies, IAIS VSTU. The purpose of the survey was to obtain an effective insulating material for wall building envelopes, in high-rise housing construction and of the material for use in low-rise construction in the manufacture, which would maximize the use of local raw and production resources. When selecting components, special attention was paid to the resource base of existing enterprises of Volgograd, analyse the products of local manufacturers. The tests were conducted in the laboratory and on the production line. It is known that the slag used in the production of building materials rarely, usually just transported to dumps by truck. At the plants, open hearth plants, slag with shlakovoza buckets are taken and poured as a melt into slag pits. Use water spraying for crushing slag due to thermal shock when the temperature drops.

Paper deals with the analysis and synthesis of geographically distributed systems for storage of hazardous substances from the environmental safety position. Particular attention is paid to the information layer to ensure environmental safety (ES) of these systems, which operates on the results of the processing of regulatory documents, environmental monitoring data, analytical reports, etc. Its operation is based on a system of specialized automated workplaces (AWP), each of which generates a plurality of projections and calculations in order to provide ES, using information on three levels of detail: the physical, technological and logical. The structures of mathematical, informationtion, software and hardware provision of AWP are discussed. It is shown that the proposed AWP structure can be used in the design of the various systems for storage of hazardous substances and is aimed to provide ES in their operation.

From the standpoint of environmental safety paper deals with the analysis and synthesis of geographically distributed systems for storage of hazardous substances. The main attention is paid to the technical maintenance of ecological safety of these systems which is determined by the layer of tool control system (TCS) in ecological situation monitoring channels, storage of hazardous substances and protection parameters of perimeter storage. Operation of TCS relies on the use of fiber-optic sensors based on fiber Bragg gratings in each of said channels and their methods of polyharmonic probing. Defined principles of joint measurement of temperature and pressure as the main storage options, optical absorption measurements of gas concentrations using remote multicomponent fiber optic infrared analyzer for monitoring the environmental situation are discussed. The information about the construction of storage areas perimeter security systems sensors are given. It is shown that the proposed TCS structure can be used in the design of the various systems of hazardous substances storage and is aimed at addressing issues of environmental safety in their operation.

The article proposes to use to describe the polar equations of nonlinear resistive two-terminal corresponding differential equations. This simplifies the implementation of non-linear resistors based on analog-digital-analog element. Constant coefficients in the mathematical model are treated as constants of integration. Therefore, the element setting the desired current-voltage characteristic is accomplished by setting appropriate initial conditions.
