The article analyzes the accumulation of mobile sulfur in the soil of the city of Atyrau. Atyrau city is located in the western part of the Republic of Kazakhstan. The main source of pollution of the city of Atyrau is the Atyrau Oil Refinery. The increased content of hydrogen sulfide in the air involves an analysis of the accumulation of sulfur in the soil, as well as establishing a relationship with the incoming hydrogen sulfide from the air. The content of mobile sulfur in the soil was determined by photometric method in the Testing Laboratory of Analytical Laboratory for Environmental Protection LLP. Accumulations of sulfur in the soil were recorded at observation points located near the Atyrau oil refinery, for example, at the observation point of Khimposelok, Mirny, Proparka. There is no such pattern in observation points located in populated areas. At the point of PNZ 1, an increased sulfur content is observed in the soil due to its close location to the Kvadrat evaporator pond.
