Component Composition of Aerosols and their Dynamics in the Atmosphere of the Baikal South-Eastern Coast
Abstract This paper presents the results of chemical composition analysis of aerosol samples taken in the summer of 1998–2001 and 2013–2021 at the southeast coast of Lake Baikal. It was revealed that the dominant aerosol ions are SO42−, NO3−, Cl−, Ca2+, Na+. In fire periods, an increase in the propo...

| description | Abstract This paper presents the results of chemical composition analysis of aerosol samples taken in the summer of 1998–2001 and 2013–2021 at the southeast coast of Lake Baikal. It was revealed that the dominant aerosol ions are SO42−, NO3−, Cl−, Ca2+, Na+. In fire periods, an increase in the proportion of nitrate ions, chloride ions, calcium ions, sulfate ions, bromide ions in suspended particles on average up to 10 times or more compared to background conditions, as well as the proportion of metal ions (calcium, potassium, sodium). The found high correlation between potassium ions and chloride ions (r = 0.8–0.9) indicates the predominant proportion of potassium chloride in the composition of atmospheric aerosols at Baikal. In case of smoke emission from the centers of intense wildfires, the proportion of secondary components in the long-range transport of smoke aerosol as a result of its aging was higher than in a regional wildfire (51.6% versus 40.5%). |
