[The influence of the oil and gas industry on environmental safety and population health in the Khanty-Mansiĭskiĭ Region - Iugra].

Production activities of oil and gas industry plants are related to technogenic impact on the environment, which has a high environmental risk. This is associated with low levels of environmental orientation of sheer technological processes of exploration and exploitation of hydrocarbons and also used in this technical means, materials and chemical reagents. The main pollutants that deteriorate the toxic characteristics of drilling waste, are the most likely drilling fluids, mud flush agents and chemicals, which enter into their composition. Existing methods of disposal of drilling wastes are not effective, the technology of their use is often violated. Dumping drilling waste into water bodies and burying toxic waste in water protection areas under the guise of processed waste has been observed. In the region there are significantly exceeded the national average values rate of morbidity of allergic, cardiovascular, pulmonary and cancer diseases, mediated by environmental factors and new monofactorial and multifactorial diseases appear.
