【 摘 要 】

This work is devoted to the investigation of the dispersed composition of ash and slag wastes of municipal services. Based on the results of the studies, recommendations were developed to improve the methods for calculating the level of negative impact of urban services with storage and disposal yards for ash and slag wastes. The relevance of the study is connected with the assessment of the level of urban air pollution by emissions of fine dust. It has been experimentally proven that the storage and disposal yards for ash and slag wastes are sources of particulate emissions of different diameters, including fine particles less than 10 μm (PM10) and less than 2.5 μm (PM2.5). Recommendations have been developed to improve existing methods of calculation of emissions of solid particles with the subsequent calculation of concentration of fine dust. The results of the approximation are presented in the processing of experimental data on diffraction distribution of the mass of solid particles entering the atmospheric air from storage and disposal yards of ash and slag wastes.
