Abstract:Changes in chemical runoff of the main tributary of Lake Baikal, the Selenga River, observed since the mid-1990s, and determinant factors of these changes are under consideration. The estimates derived are indicative of a 20–40% reduction in the annual removal of dissolved substances because of a decrease in the water runoff of the river due to climate oscillations. The decreased inflow to Lake Baikal of mineral substances, especially silicon, nitrogen, and phosphorus, can lead to disturbance of production processes in Lake Baikal.
