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 2016 compared to 2015, the removal of suspended substances increased by 1,3 times, and the removal of organic substances grew by 32%. The main reason for the increase in removal is the increase in the aqueous runoff.
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).
According to the monitoring data for 2016, the volume of atmosphere substance inputs was within the fluctuations of the last decade.
