【 摘 要 】

In the paper, we compared the dynamics of the carcinogenic benzo(a) pyrene content in the atmospheric air of cities and the rates of forest fires in the territory of the Irkutsk region for the period 1987-2015. We found positive linear dependencies between the mean concentrations of benzo(a)pyrene in the atmosphere and the intensity of fires. It was shown that the accuracy of correlations is higher for the last 10-15 years, which may indicate an increase in the contribution of wildfires to atmospheric pollution as compared to other sources.
