The contribution of emissions from industrial zones of Izhevsk to the formation of the medical and ecological situation

Abstract

The article presents a brief 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 a distance of 2-3 km from the borders of industrial zones in the direction of the prevailing south and south-west winds. A territorial analysis of the general incidence rate of the child population in the service territories of 12 childrenʼs city clinics and 170 pediatric 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 a significant reduction in emissions by enterprises of this industrial site, it should be noted its significant contribution to the formation of a tense 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 a significant 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 %.
