Abstract: The analysis of atmospheric precipitation composition is essential for understanding the processes of atmospheric pollution and self-purification, especially in regions located at the border of natural and climatic zones, such as the Altai Krai. A crucial aspect is the separate accounting of dry and wet deposition, which allows for obtaining more accurate and representative data. Therefore, the aim of this work is a comprehensive assessment of the qualitative and quantitative characteristics of dry and wet deposition of major ions onto the underlying surface of the plain territory of the Altai Krai, using the city of Barnaul as an example. It was established that the major ions in atmospheric deposition are SO₄²⁻ and Ca²⁺. Seasonal differences in the ionic composition of the ambient atmosphere were identified for the warm and cold periods of the year. Flux calculations showed that wet deposition is the dominant pathway for the input of substances onto the surface of the study area (67–99% for different ions).
