Химический состав притоков оз. Байкал и его трансформация в зоне смешения речных и озерных вод

Abstract

Seasonal and interannual dynamics of biogenic element concentrations in the water of the Lake Baikal tributaries is largely dependent on climate change and anthropogenic load, while the water content conditions mainly determine their removal to the lake. In the lake, quantitative and qualitative changes in the biogenic elements of the river flow occur at a distance of 3–4 km from the river mouths. In the mixing zone, during vegetation the biological cycle involves up to 50–60 % of nitrate nitrogen and 70–80 % of mineral phosphorus
