Abstract
Ozone is one of the most toxic impurities in the troposphere. Therefore, it is recognized as the number one pollutant in most countries and its concentration is monitored. This work presents an overview of continuous measurements of the ozone content in the troposphere over Russia throughout 2021 carried out on an initiative basis at 16 stations in different Russian regions. The monitoring results showed that the daily mean ozone concentration exceeded the MPCdm at all observation sites during a significant part of the year. Two- and even three-fold excess over MPCdm was observed at a number of stations. At six stations, concentrations above the MPCs were recorded. This requires a more comprehensive analysis of the composition and concentration of ozone precursors and the development of measures to reduce their emission into the atmosphere.
