The article presents abrief description of the main industrial zones of Izhevsk as sources of air pollution. The potential aerotechnogenic hazard of industrial sites, their contribution to the formation and spatial differentiation of the complex atmospheric air pollution index, based on the volume and structure of pollutant emissions, are estimated. Air sampling at flare observation posts allowedto conclude that the maximum concentrations of pollutants are observed at adistance of 23km from the borders of industrial zones in the direction of the prevailing south and south-west winds. Aterritorial analysis of the general incidence rate of the child population in the service territories of 12childrenʼs city clinics and 170pediatric sites confirms these findings. The most disadvantaged situation is typical for microdistricts located in the north and northeast relative to the Central industrial zone. Despite asignificant reduction in emissions by enterprises of this industrial site, it should be noted its significant contribution to the formation of atense medical and environmental situation in most residential areas of the city. The increase of emissions in recent years, the largest northeastern industrial zone in Izhevsk, even taking into account its most favorable ecological and geographical position, has led to asignificant increase in the general incidence and prevalence of respiratory diseases of the children in the adjacent territory. In the formation of inhaled non-carcinogenic risk to public health, the contribution of formaldehyde is more than 90%.

The distinctive features of the noise protection legislation at the level of 85 subjects of the Russian Federation are considered. The comparative characteristics of the time parameters “day”, “night” for working days and holidays are given. It is compared with similar indicators of other countries. 46% of subjects considered 7 am as the beginning of the “day” period; 61% considered 22 pm as the beginning of the "night" period. For the first time Russia developed the following time periods separately: “day rest”, “evening”, “weekends and holidays”. The penalty system for violation of the noise legislation is analysed. Irkutsk region has the “smallest” fines in Russia and Novosibirsk and Belgorod regions have the “biggest” fines.
