Abstract

The results of monitoring of the concentrations of gas impurities (SO₂, NO, NO₂, O₃), aerosol particles of different fractions (ultrafine and submicron aerosols) in the coastal zone of the Lake Baikal (Boyarsky station) in different seasons of the year (spring, summer, autumn) during the experiments of 2022 are presented. It was revealed that in the spring months, the highest average daily concentrations of ozone (O₃), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and the number concentration of nanometer-sized particles are observed compared to other seasons. In the summer months, the proportion of particles of the submicron size range increases, due to an increase in the contribution of not only anthropogenic sources of emissions, but also natural sources (wildfires) during this period of the year.
