Environmental monitoring of Lake Baikal
Hydro-chemical characteristic of Lake Baikal water
The annual data of hydrochemical observations in the 200-metre layer of Lake Baikal in 2014
The page shows the map of the BNT with the display of water observation areas of Lake Baikal according to the hydrochemical indicators. If you hover over the observation area, the annual data of hydrochemical observations in the 200-metre layer of Lake Baikal in 2014 will appear in the pop-up window.

Conclusions.
1. Closedown of the Baikalsk Paper and Pulp Mill (BPPM) in 2013 and reduction of wastewater discharges by 91% in 2014 compared to 2013 contributed to the improvement of the water quality of Lake Baikal in the area of the BPPM and the city of Baikalsk.
2. In 2014, at the source of the Angara River, chemical composition of the lake water corresponded to the data of the background section.
3. The anthropogenic load on Lake Baikal in the area of BAM influence in 2014 decreased compared to previous years of observations.
