Аннотация: The results of the analysis of atmospheric air samples for 4–6-nuclear aromatic hydrocarbons at the State monitoring network in 143 cities of the Russian Federation in the winter season 2019‒2020 are presented. Comparative analysis of the situation with air pollution with PAHs in cities at the territories of Federal districts of Russia is performed. The analysis showed that the levels of 4–6-nuclear PAHs in the atmospheric air of cities in the European part of Russia are significantly lower than in the Asian part of the country in winter. The average concentrations of 4–6-nuclear PAHs in the air of some cities of the Siberian Federal District were more than anorder of magnitude higher than in the cities of the European part. High (5‒10 MAC) and very high (> 10 MAC) air pollution with benzo(a)pyrene in winter is observed only in the cities of the Siberian (63% of the surveyed cities)and Far East Federal Districts (Yuzhno-Sakhalinsk). A method is proposed for comparing the similarity of PAH profiles in environmental matrices using the similarity coefficient (Ks). It was noted that the PAH profiles in theatmospheric air of the Siberian and Far Eastern Federal Districts differ appreciably from the respective profiles in the Federal districts of the European part of Russia. The pyrogenic nature of medium- and high-molecular PAHs in the atmospheric air in cities of all Federal Districts was revealed. Higher pyrogenicity indices were obtained for the cities of the Siberian and Far Eastern Federal Districts.
