It is shown that priority pollutants posing hazard to public health in the zone influenced by emissions of "Karachaganak Petroleum Operating BV" Limited Liability Partnership (TOO) at the Karachaganak oil and gas condensate field (KOGCF) are nitrogen dioxide and oxide, sulfur dioxide and hydrogen sulfide.It is found that hazard indexes for the most affected critical organ system (respiratory) calculated for the population living near the borders of the sanitary protection zone of the object, did not exceed 1.0 both for short-and long-term exposure, which indicated an acceptable risk level.By chronic exposure, hazard indexes for different directions from the industrial area were more than by 50% influenced by levels of nitrogen dioxide and sulfur dioxide, while the risks of acute exposure are mainly determined by exposure to hydrogen sulfide.The data obtained can be used in organization of sanitary protection zone of a plant, conservation measures planning, including industrial ambient air quality control in the zone influenced by emissions from the plant.Key words: industrial emissions, sanitary protection zone, risk assessment, non-carcinogenic and carcinogenic risks.Safe conditions of living in the areas adjacent to large industrial complexes being the sources of negative impact on the environment and human health, are traditionally provided by organization of sanitary protection zones [1,2,4,5].In the context of the sanitary legislation requirements, the dimensions of a sanitary protection zone are established in accordance with the sanitary classification of plants and depend on plant´s capacity, operating conditions, nature of the object and the amount of emitted pollutants.The newly approved "Sanitary regulations on the establishment of sanitary protection zone of production facilities" Sanitary regulations No. 93 of 17.01.2012,state that the substantiation of a sanitary protection zone for industrial facilities of I and II hazard classes requires assessment of health risk posed to the population living near an industrial facility.[9] However, it should be noted that the risk Kenesariyev U.I., Dosmukhametov A.T.,
