STATE OF ATMOSPHERIC AIR IN KHARKIV AND KHARKIV REGION

Abstract

The risk of chemical pollution is assessed by the level of its possible negative impact on the atmosphere, soils, groundwater and surface water, vegetation, animals and humans. The state of atmospheric air in Kharkiv and Kharkiv region is analyzed and it is revealed that atmospheric air pollution comes from mobile and stationary sources of pollution. One of the main sources of pollution is thermal power plants and oil and gas companies. The largest number of emissions from stationary sources is in Zmiiv, Krasnograd, Balakliia, Chuguiv districts and Kharkiv. The largest number of emissions from mobile sources is observed in Kharkiv and Derhachiv districts. The most polluted areas of the city of Kharkiv were identified, especially the central district and the area of the railway station, and the causes of pollution were established. As a result of comparison of the accepted maximum admissible concentrations of chemical substances in Ukraine, the USA and the countries of the European Union it is revealed that the Ukrainian norms are stricter. An analysis of emissions since 1990 found that their 9,14-fold reduction was due to a reduction in production and the closure of some enterprises as a result of the collapse of the Soviet Union. The sharp drop in emissions since 2013 is also due to the economic crisis and hostilities in eastern Ukraine. The reduction of emissions is explained not only by the reduction of production volumes, but also by the implementation of air protection measures carried out at the enterprises of the city and the region. There is a close link between pollutant emissions and gross domestic product (GDP) production, which can be used in the future to forecast emissions. Measures aimed at improving the state of atmospheric air in Kharkiv region and the city of Kharkiv are presented.
