ASSESSMENT OF TECHNOGENIC IMPACT ON THE AIR BASIN OF THE UKRAINE NORTHERN REGIONS

Abstract

The problem of pollution and technogenic impact on the air basin remains particularly acute for the regions of Ukraine. The paper evaluates and analyzes the technogenic impact on the air basin of some northern regions of Ukraine (Zhytomyr, Chernihiv and Sumy). According to the National Report, pollutant emissions in these regions from stationary sources are insignificant compared to other regions. But the predominant sources of emissions remain mobile. The materials of the Regional Reports on pollutant emissions for 2015–2020 were used as initial data. The module of technogenic load MAB on the air pool was used to assess. The impact of production activities on the state of the air basin was also analyzed using the coefficient of environmental damage СED from emissions of pollutants to the atmosphere by stationary sources. It was found that in Zhytomyr and Sumy regions the indicators of total emissions are almost comparable for the study period. In the Chernihiv region since 2017 there has been a significant reduction in emissions of pollutants. The contribution of mobile sources of pollution is maximum in Zhytomyr region, minimum – in Chernihiv region. The level of technogenic load according to the MAB is the maximum in Sumy region. With the maximum values of pollutant emissions in 2015–2016 in the Chernihiv region, the level of technogenic load is lower compared to Sumy region. The value of СED in Zhytomyr region is on average higher than in Chernihiv region. There has been a significant decrease in the number of СED registers in the Chernihiv region, which indicates an improvement in environmental safety from the production activities of the region. The obtained results can be specified taking into account the same list of pollutants that are taken into account in the calculations.
