PECULIARITIES OF FORMATION OF CARCINOGENIC RISK UNDER THE INFLUENCE OF TECHNOLOGICAL EFFECTS OF PETROCHEMICAL TYPE

This paper presents the results of a study of the quality of drinking water and atmospheric air in order to identify the concentration of hazardous substances and their effect on human health. To assess the risk, a territory located 1990 m from a petrochemical enterprise, the main source of pollution, was chosen. The activity of the industrial facility is the manufacture of various products of petroleum feedstocks, which entails the emittance of non-carcinogenic substance, namely ethylene and carcinogens, including benzene, epoxyethane, chrome VI, divinyl, cadmium into environment. The paper also presents the results of a sociological survey of residents of the study area, whose purpose was to identify the characteristics of the impact of pollutants on them. Thus, it was found that the majority of respondents noted deterioration in the quality of water consumed the presence of odors in the air, as well as the detrimental effects of the activity of the plant on their well-being and health in general. During the research work, the main risks were identified and evaluated; their indices and hazard ratios were calculated. This analysis established the groups of danger the detected elements belong to and how they affect the organism of the population. The most vulnerable systems of the body of the surveyed residents are cardiovascular and nervous. Keywords: ecology, environmental pollution, non-carcinogenic risk, carcinogenic risk, risk assessment, technogenesis, petrochemical enterprise, sociological survey.N
