Assessment of the Contribution to the Pollution of the Atmosphere of Technogenic and Natural Fires in the Irkutsk Oblast

Abstract

On the example of the Irkutsk oblast, the problem of air pollution with technogenic and natural fires is considered. The factual basis of the study was the statistics of the consequences of fires in residential, public, industrial and other objects of the technosphere and natural fires, also combustion of forest combustible materials in the residential, landscape-recreational, forest-park, suburban zones of cities and settlements for 2011-2016. On the basis of existing approaches, qualitative and quantitative indicators of burned materials are determined as a result of technogenic and natural fires, ignition, and specific indicators of toxicant emissions in the combustion of various types of materials, which allowed to comprehensively determine the gross emissions of pollutants in the Irkutsk oblast. It is established that as a result of technogenic and natural fires, ignitions, the annual gross emissions of pollutants averaged about 18.2% of the mass of stationary sources of pollution in the oblast.
