Variations in the concentrations of both primary (PM10, CO, and NOx) and secondary (ozone) pollutants in the atmosphere over the Moscow and Kirov regions, Kiev, and Crimea under the conditions of the anomalously hot summer of 2011 are given and analyzed. The concentrations of ozone, PM10, CO, and NOx in the atmosphere over the Moscow region exceeded their maximum permissible levels almost continuously from late July to late August 2010. The highest level of atmospheric pollution was observed on August 4–9, when the Moscow region was within a severe plume of forest and peatbog fires. The maximum single concentrations of ozone, which exceeded its maximum permissible level two-three times, were accompanied by high concentrations of combustion products: the concentrations of PM10 and CO were also three-seven times higher than their maximum permissible concentrations. The maximum levels of air pollution were observed under the meteorological conditions that were unfavorable for pollution scattering, first of all, at a small vertical temperature gradient in the lower atmospheric boundary layer. The number of additional cases of mortality due to the exceeded maximum permissible concentrations of PM10 and ozone in the atmosphere over Moscow was estimated. Under the weather conditions that were close to those for the Moscow region, the air quality remained mainly satisfactory in the Kirov region, Kiev, and Crimea, which were almost not affected by fires.
