The diagrams provide an estimate of the removal of substances with aqueous runoff from the main stream tributaries of Lake Baikal – the rivers Selenga, Upper Angara, Barguzin and Turka. The aqueous runoff in the main-stream sections of the listed large tributaries of the lake was estimated on the basis of the adjusted average monthly water consumption. In 2019, compared to 2018, вынос взвешенных веществ увеличился на 142%, and organic substances decreased - by 121%.
Observations were carried out at five stations (stationary): Baykalsk, Khamar-Daban (southern coast of the lake), Angara Source, Bolshoye Goloustnoye (west coast of the southern part of Lake Baikal) and Khuzhir (Olkhon island, middle Baikal).
The values of substances released from the atmosphere obtained according to the 2019 monitoring data were within the limits of the oscillations of the last decade.
