Аннотация

We present the materials on the concentration of petroleum products in the water of Lake Baikal and its tributaries from 2010 to 2019. Southern Baikal showed elevated concentrations of petroleum products. We revealed seasonal and interannual dynamics of concentrations of petroleum products in the tributaries of the lake. The bulk of petroleum products enters the rivers with the surface runoff of precipitation. We assessed the pollution degree of water in comparison with sanitary and hygiene standards.
