Abstract

The Odesa industrial and urban agglomeration is formed around the city of Odesa and includes part of the surrounding settlements that are closely connected with the regional center. This territory is the largest port and industrial complex in Ukraine, located on the North Western coast of the Black Sea. An important issue for the Odesa industrial and urban agglomeration is ensuring adequate air quality, as this territory also serves recreational purposes. The purpose of the study is to assess the technogenic impact on the air basin of the Odesa industrial-urban agglomeration using various methodological approaches. It has been determined that the highest values of the environmental damage coefficient С_ED are observed for the city of Odesa. The level of environmental safety of industry in the cities of Chornomorsk and Pivdenne is significantly better than in Odesa. The best conditions for environmental safety are observed in the cities of Teplodar and Bilyayivka. In the value of the integral indicator of the environmental state Patm the cities of Odesa, Chornomorsk, and Pivdenne are characterized by approximately comparable values. The Patm values for the cities of Teplodar and Bilyayivka are two orders of magnitude lower. The trend in the change in the module of technogenic load on the air basin of the M_AB fully corresponds to the trend in the change in the Patm indicator for individual cities of the Odesa industrial-urban agglomeration. A point rating is proposed to determine the level of technogenic load on the air basin. It was obtained that the group with the highest scores is formed by the cities of Odesa, Chornomorsk, and Pivdenne, while the group with the lowest scores is formed by Teplodar and Bilyayivka. The total technogenic impact, taking into account environmental damage, is mainly formed by three cities: Odesa, Chornomorsk, and Pivdenne. These three cities are also the main ones in the assessment, taking into account the ecological and economic components of the territory. In terms of M_AB values, the predominant total impact is formed by four cities of the Odessa industrial and urban agglomeration.
