title: [Hygienic evaluation and prediction of population morbidity in the region of the Karachaganak field].
abstract: The state of pollution of the environment in the area of operation of the Karachaganak oil and gas field depends on the development and operation of oil and gas objects. According to the analysis of retrospective studies, periods of the increase in air pollution have two peaks occurring in 1990 and 1997. However, these negative environmental moments are significantly different. In 1990, due to a sharp increase in the production of hydrocarbon crude, as well as the low efficiency of gas cleaning devices air pollution has increased significantly. The second period was characterized by a slight increase in the concentration of nitrogen dioxide only that was directly connected to the introduction of new technologies reducing environmental pollution. At the same time, the average population morbidity rate in settlement Berezovka is 336.8 cases per 1,000 surveyed, which is lower in 1.6 times than the reference data in the control townships. The leading place in the structure of morbidity are taken by digestive diseases, respiratory diseases and diseases of the nervous system, diseases of the eye and its appendages, diseases of the genitourinary system, diseases of the circulatory system, accounting for 87.6% of all diseases of the surveyed residents of settlement Berezovka. There was shown a multi-dimensional model of the dependence of general population morbidity in settlement Berezovka on the concentration of SO2 and NO2 in air. Also found depending on the influence of the concentrations of H2S, SO2 and NO2 in the air on the population on basic classes of diseases.
