Abstract

Introduction. Operation of enterprises of petrochemical and oil refining industries is accompanied by significant pollution of air, soil, underground and surface water sources with a complex of toxic chemical compounds, which in turn has an adverse impact on the health and living conditions of the population. In order to carry out a correct assessment of the ecological and hygienic situation and reduce the risk to public health in regions with developed petrochemistry and oil refining, there is a need to optimize the existing mechanism of sanitary and epidemiological supervision of the quality of environmental facilities, to develop effective hygienic recommendations and targeted measures to reduce the level of anthropogenic impact and to prevent poor living conditions. Material and methods. The analysis of quality of objects of the environment according to departmental laboratories in territories of placement of the enterprises of petrochemistry and oil refining for 2007-2018 is carried out; results of scientific and practical researches and publications on the studied problem for 2004-2017. Results. There are identified the major sources and reasons for the admission of harmful chemical substances in the environmental objects from the petrochemical and refining industries. The most part of the enterprises of branch was established to operate for a long time, the outdated equipment, the power-consuming while there are used imperfect technologies characterized by insignificant depth of processing of raw materials and representing danger of ecological risk for objects of the environment. The list of priority indices recommended for the control of atmospheric air, soil, water bodies in the areas of petrochemistry and oil refining is based on. Developed and tested an algorithm of assessment of environmental quality and the health risk of the population in the territories with developed petrochemical industry and oil refining. On the basis of the obtained results, approaches to the development of hygienic recommendations and targeted measures to reduce the tested man-made load of the territories are proposed. Conclusion. The proposed methodological approaches will optimize the assessment of an ecological and hygienic situation, develop preventive measures to reduce the level of man-made impact and prevent poor living conditions in regions with developed petrochemistry and oil refining.
