Abstract
Aim. The study of the degree of influence of natural factors in the Trans‐Baikal region on the quality of the air of the city of Petrovsk‐Zabaykalsky, which lies in an intermountain basin. Material and Methods. The geomorphology and climate of the intermountain basins of the Trans‐Baikal regions, as well as their separation by orographic features, were studied. Missing points were identified which need for further scientific research regarding the influence of natural factors of the Trans‐Baikal region on the quality of the air. Results. Geographical and natural factors in the formation of the qualitative composition of the atmosphere of cities located in intracontinental intermountain basins are presented. Studies were conducted from 2005 to 2015 at three observation posts (hereinafter – OP) in the city of Petrovsk‐Zabaykalsky (Н1 = 800 m; Н2 = 860 m; Н3 = 895 m). The dynamics of the average values of pollutant content in the air of the city of Petrovsk‐Zabaykalsky for the period 2005‐2015 were considered (based on field observations from three OPs), as well as the dynamics of the atmospheric pollution index of benzo(a)pyrene in the air in Petrovsk‐Zabaykalsky for the period 2005‐2015. Geoecological threats were assessed together with the geographical mechanisms responsible for them and the dynamics of atmospheric air pollution of a characteristic situation (the Tugnui basin and atmospheric air of the city of Petrovsk‐Zabaykalsky) were studied. The regular occurrence of extremely dangerous concentrations of pollutants in the atmosphere of cities located in intermountain basins is presented. Conclusion. The author’s research into the influence of natural factors (using the example of the Tugnui basin) on the air quality of a city on the National Priority List (e.g. the city of Petrovsk‐Zabaykalsky) showed that extremely dangerous concentrations of pollutants, especially substances of the first hazard class, namely benzo(a)pyrene, are created because of geographical factors.

Summary
Возникает необходимость проведения дополнительных исследований природных факторов Забайкальского края, влияющих на качество воздушной среды населенных пунктов, расположенных в условиях межгорных котловин. Задача исследования – изучение при‐ родных факторов Тугнуйской котловины, влияющих на качество воздушной среды города. Уровень загрязнения атмосферы в целом по городу – высокий / Level of air pollution in the whole city ‐ high
