Pollution of substances entering the atmosphere as a result of natural fires significantly affects the morbidity level of the Irkutsk region population. The development of measures to reduce it requires an assessment of the risk level and analysis of spatial differences in the composition and number of major issuers. The study is based on statistical data on natural fires in the region in 2014-2019. The comparative analysis of the composition and mass of substances from natural fires on three categories of land have done. These are: forest lands; residential, suburban, recreational lands; peat and peat soils. Peat fires are the most dangerous for health according to the weight and composition of pollutants. The level of health risk as a result of natural fires varies by region within two orders of magnitude. It is affected by the proportion of the area of smoke from the total area of the district, nonuniform distribution of the population within the district, sparsely populated and difficult to access, economic specialization, and others.
