Current assessment of atmospheric pollution by industrial enterprises in Ust-Kamenogorsk based on GIS technologies

The article discusses the engineering geological conditions for the cadastral assessment of urban lands, in value terms, the calculation of the area of distribution of hazardous substances in the atmosphere from industrial and other waste sources. The method of zoning territories by pollution level and a cartogram of distribution of hazardous substances in the atmosphere by allocated territories were provided. The following factors and their influence were studied in detail: spatial planning, zoning, cost of land development, engineering and transport infrastructure, physical properties of land, environmental conditions of air, water, soil, nature of construction, nature of the settlement, wind direction. The basis of obtained quantitative, qualitative data, determination in specific territories using geoinformation systems technology (GIS) was considered. The algorithm for assessing the state of atmospheric air in real time includes the integration of the obtained data and modeling the current state of the atmosphere. The study was conducted in the city of Ust-Kamenogorsk, where there are several industrial plants, such as Kazzinc, Ulba Metallurgical Plant (UMP), Titanium Magnesium Plant (TMP). The study results and the calculated coefficients for assessing the atmospheric pollution allow us to draw individual conclusions on the territory of a zoned city. The practical value of the work is providing an algorithm for assessing the state of atmospheric air in real time using the presented results, modeling the state of atmospheric air in each point of the city and qualitative assessment of regions for environmental friendliness in the cadastral system.
