This study aimed to reveal air pollution and its influence on pathology of upper respiratory tract in teenagers of Angarsk and Sayansk. The quantitative content of chemical substances in the atmospheric air of the celitebic territory of Angarsk and Sayansk was studied based on the data of the hydro-meteorological center, the content of chemical substances in indoor air was assessed based on studying of the educational institutions. Two territories with a different pollution level were chosen to investigate in Angarsk. The higher summary risk of forming the respiratory organ pathology stipulated by the indoor air pollution and the atmospheric air with the tropic substances to the systems indicated was revealed to be in the schoolchildren in Angarsk. The studies performed in the educational school rooms have shown that on the whole the largest pollution degree was induced by the suspended substances. In the educational school rooms studied in Angarsk the increase in the hygienic normative on suspended substances was found to be in the educational classes in 43 % of samples, in the computer classes and in the sporting halls - in 44 % of samples. Sometimes the increase in the limited allowed concentration (LAC) was more than 2 times. The increase in the LAC of formaldehyde was observed to be in 13 % of samples in the educational classes. In the incidence structure according to applying for medical assistance the respiratory organ diseases were found to occupy the first place, at the same time the pathology of the upper respiratory ways prevailed in both towns. The chronic glandular and adenoid diseases as well as the allergic rhinitis were more often revealed. In comparison of the regions in Angarsk which are different in the pollution levels, it was found that the chronic pathology of the upper respiratory ways occurred 1,4 times more often in first region than in second one and 2,8 times more often than in Sayansk.
