AN ANALYSIS OF METEOROLOGICAL CONDITIONS AND CONCENTRATIONS OF ATMOSPHERIC IMPURITIES IN THE CITY OF UFA

Based on instrumental measurements of Roshydromet network for the city of Ufa, an analysis of meteorological conditions and the level of atmospheric air pollution was performed. The bases for the analysis were observations of concentrations of suspended solids, sulfur dioxide, carbon monoxide, nitrogen dioxide and hydrogen sulfide at 9 stationary stations from 2017 to 2021. A comparison of data from the observation network of Roshydromet and the Center of Hygiene and Epidemiology in the Republic of Bashkortostan was performed. When analyzing the quality of atmospheric air along with the maximum permissible concentration (MPC), the associated air pollution index (API) was used. It was established that the level of air pollution for 2017-2021 in the city of Ufa was elevated and was mainly determined by high concentrations of nitrogen dioxide and suspended solids. Meteorological conditions of recent years also contributed to the increase in the concentration of pollutants in the atmosphere of the city: when the number of days with precipitation decreased, the frequency of air stagnation and elevated temperature inversions increased.
