ASSESSMENT OF TECHNOGENIC LOAD ON THE AIR BASIN OF THE WESTERN UKRAINE REGIONS

The issue of assessing the technogenic load on the air basin in the regions of Ukraine, especially under martial law conditions, is highly relevant. The territory of Western Ukraine, in general, does not belong to regions with high load indicators compared to other regions. However, some scientific works are dedicated to assessing the state and specific types on the air basin load of the western regions of Ukraine. The aim of this study was to assess the state of the air basin in the regions of Western Ukraine under the influence of technogenic activity over the period 2005–2023. The module of technogenic load on the air basin (МAB) and the integral indicator of atmospheric air condition (Iatm) were applied. The highest emission levels were recorded in Ivano-Frankivsk and Lviv regions, while the lowest were in Chernivtsi region. The application of two indicators for assessing technogenic load showed similar results. The substances most frequently associated with the likelihood of developing non-carcinogenic health effects included nitrogen dioxide, formaldehyde, and some specific pollutants. The highest indicators of the combined impact of pollutants on the potential development of non-carcinogenic effects were observed in cities such as Lutsk, Uzhhorod, Lviv, and Rivne. In recent years, there has been an almost noticeable trend of a slight decrease in technogenic impact indicators.
