    Statistical assessment of the dynamics of changes in the PM10 and PM2.5 level in the air of urbanized areas
    (Видавництво Львівської політехніки, 2023-02-28) Sabadash, Vira; Lopushansky, Oleksiy; Lysko, Vitaliy; Lviv Polytechnic National University
    This article addresses the issue of atmospheric pollution caused by solid particles in urban environments. The presence of PM10 and PM2,5 particles in the air of major cities and industrial areas worldwide has been examined. An evaluation of atmospheric pollution levels with PM10 and PM2,5 particles in Kostopil, considering current air quality standards in Ukraine and the European Union, has been conducted. The authors employed the gravimetric method to measure the levels of suspended dust particles (PM10 and PM2,5) in Kostopil from autumn 2022 to winter 2023. The study revealed an excessive amount of fine dust particles in the city's air, exceeding the maximum permissible values outlined in regulatory laws by 2.1-2.7 times. Furthermore, the monitoring of changes in suspended dust particle levels showed peak values of PM10 = 1.15 mg/m³ in January and PM2,5 = 0.96 mg/m³ in December. The results of the statistical analysis of particle level distribution in Kostopil's urban areas indicated the statistical significance of certain distribution parameters, specifically SW-W and D for PM10 and PM2,5 particle classes.

    Analysis of studies on the morphological composition of domestic waste in Ukraine
    (Видавництво Львівської політехніки, 2023-02-28) Illiash, Oksana; Holik, Yurii; Allesch, Astrid; Chepurko, Iuliia; Serha, Tetiana; Poltava National Technical Yuri Kondratyuk University; University of Natural Resources and Life Sciences
    The article presents the results of the analysis of the studies conducted on the quantitative and qualitative characteristics of household waste generated in the territories of several regional centers of Ukraine. The data on the component composition of domestic waste typical for Ukrainian cities are generalized. The influence of the quality indicators of individual waste fractions on the further choice of operations and methods of household waste treatment within the framework of the waste management system is analyzed. On the basis of the collected data, the expediency and relevance of the experimental studies conducted in the context of the current war in Ukraine, global environmental problems, and the global energy crisis are substantiated.
