ASSESSMENT OF TECHNOGENIC POLLUTANTS IMPACT OF THE URBAN ENVIRONMENT OF ZAPORIZHZHIA CITY ON HUMAN HEALTH OF THE SHEVCHENKIVSKYI DISTRICT

Abstract

The city of Zaporizhzhia has a large number of ferrous and non-ferrous metallurgy enterprises, machinebuilding and metalworking enterprises, construction facilities and the chemical industry, which leads to a high technogenic burden on the health of the city’s residents. The purpose of the article is to establish the risks to the health of the population of the Shevchenkivskyi district of Zaporizhzhia in the period 2019–2022 from air pollution by gaseous substances. The selected district is the largest in terms of area and population. At the same time, many industrial enterprises of the cities are located in the district: JSC Motor Sich, SE Zaporizhzhia Machine-Building Design Bureau “Progress” named after Academician O.G. Ivchenko, PJSC Zaporizhzhia Abrasive Plant, State Enterprise Research and Production Complex “Iskra”, Production Unit “Zaporizhzhia Oil Extraction Plant”. Research methods. The study used the general procedure of the Human Health Risk Assessment methodology developed and recommended by the US Environmental Protection Agency. We also used sanitary and hygienic, analytical and mathematical research methods. The scientific novelty of the work lies in the fact that for the first time a scientifically substantiated and provided riskometric assessment of the impact of technogenic pollutants of the urban environment on the human health of the Shevchenkivskyi district of the Zaporizhzhia city. Scientific data on the patterns of formation of morbidity and mortality in the district’s population as a result of industrial emissions into the air basin has been supplemented. Conclusions. It has been established that the results of calculations of hazard factors and indices in assessing the inhalation effects of pollutant emissions from industrial enterprises under chronic exposure in the Shevchenkivskyi district of Zaporizhzhia for 2019–2022 indicate the presence of exceedances of safe levels. The total hazard indices for assessing the chronic inhalation effects of pollutant emissions from industrial enterprises in the study area are at an extremely high level. The individual carcinogenic risk of chronic exposure during the study period in the Shevchenkivskyi district of Zaporizhzhia is at an average level.
