The retrospective analysis of chemical composition of water of the Bolshezemelskaya tundra lakes (Bolshoi Kharbei and Golovka)

Results of the research on the chemical composition of water of large Bolshezemelskaya tundra lakes - Bolshoi Kharbei and Golovka are presented. It is shown that for decades which had passed since the first hydrochemical inspection of lakes, there were no essential changes in ratio of the main ions, mineralization, in saturation of water by organic and biogenic substances. Natural factors play the key role in the formation of chemical composition of the lakes water.
