“…The main sources of pollution in Atyrau are oil refining and transportation facilities: Atyrau Oil Refinery, Tengizchevroil, "Atyrau Oil Company", "Embamunaigas", "Intergas-Central Asia". In addition, the city has two storage ponds of industrial discharges located on both sides of the city (the north-western side is the storage pond "Square" and the eastern side is the "Rotten Beam") [1]. All urban discharges into the storage tank are carried out practically without purification, as a result, the main source of hydrogen sulfide is formeda storage tank of 1000 hectares, in which the processes of decay of organic substancessewage, including petroleum products, are taking place [2].…”

This article analyzes the morbidity of newly identified patients in Atyrau, the Republic of Kazakhstan, also calculates the correlation between the content of hydrogen sulfide in the air and mortality from diseases for a year by decade from July 2021 to June 2022. According to the analysis of morbidity over ten years, it was determined that the maximum number was detected for respiratory diseases, in second place diseases of the circulatory systems, the number of which exceeds 16,000 and 2,000 patients per 100,000 people, respectively. The calculation of the correlation dependence showed a direct positive relationship between the content of hydrogen sulfide in the air and the mortality of people from diseases of the respiratory and circulatory systems (the correlation coefficient of which is 0.99 and 0.5 respectively), and there is a negative dependence on the mortality of neoplasm diseases (the correlation coefficient is (-0.09)). This study has limitations on data, since the incidence data were given only for decades, whereas the correlation dependence would be more accurate with more data. In the future, it's planned to continue this study and include calculations of the relationship between the number of patients and the content of hydrogen sulfide for each month.
