- Аннотация: n this article, a monitoring study was conducted on the content of hydrogen sulfide in the air of the city of Atyrau, the exceeded content of which is associated with reclamation work in the evaporation fields, where industrial wastewater from the Atyrau oil refinery and household water from all over the city have been drained for decades. Monitoring was carried out for the period from September 2021 to June 2022 on 15 observation points recorded by the Republican State Enterprise "Kazhydromet" through the mobile application “Air Kz". The measurements were carried out by the GANK-4AR gas analyzer. The data were analyzed taking into account the maximum permissible concentrations, the repeatability of concentrations of impurities in the atmosphere, the standard index, taking into account the average sample values of hydrogen sulfide content at 10 points out of 15, where increased hydrogen sulfide content was noted. Of the remaining these 10 points, the highest value was noted in the Drag and drop AOR (Atyrau Oil Refinery) point, the hydrogen sulfide content in which, according to the average maximum values, exceeded more than 36.5 MPC (maximum permissible concentration). In general, by month, we note that high values for the average values of the maximum hydrogen sulfide indicators were noted in September, April and June months. Especially strong increase is characterized during warm periods in industrial areas and residential areas as NCOC No. 109 (Vostok), NCOC No. 110 (Privokzalny), NCOC No. 112 (Akimat), NCOC No. 111 (Zhilgorodok), NCOC No. 113 (Avangard) and NCOC No. 114 (Zagorodnaya) points.
