Characteristics of the risk to the health of the population of the oil-producing region associated with environmental factors

Abstract

Introduction. The activities of enterprises engaged in the production, preparation, transportation and primary processing of oil are associated with the formation and accumulation of a large amount of waste (spent drilling fluids, drilling mud, oil sludge, spent catalysts, etc.), which leads to pollution of environmental objects and can contribute to the formation of adverse effects on public health. Materials and methods. The sanitary and hygienic state of atmospheric air, soil, the water of surface (rivers, lakes) and underground (wells, wells, springs) water sources, the water of centralized water supply systems in the territories of large oil fields the Republic of Bashkortostan is carried out. The origins of information were data from many years of in-house research, the regional information fund of the Sanitary Hygienic Monitoring, and departmental laboratories. Results. Studies have found that in areas of oil production, the content of chemicals in concentrations exceeding hygienic standards is detected: in the atmospheric air - dihydrosulfide, hydrocarbons, nitrogen dioxide, sulfur dioxide; in underground waters - chlorides, sulfates, nitrates, iron, strontium, increased mineralization and general hardness; in the soil - sulfates, chlorides, nitrates, petroleum products. Contamination of water from underground water sources and atmospheric air can contribute to the risk of adverse effects from individual organs and systems, as well as carcinogenic hazards. Based on the results of the study, ecological and hygienic recommendations were developed. Conclusion. As a result of the study, the level of public health risk associated with environmental factors in the oil-producing region was assessed, and a set of hygienic measures was justified.
