The long-term dynamics of hydrochemical indices of low-mineralized subarctic lakes in reducing the acid load
The results of long-term studies (1990–2013) of dynamics of the main hydrochemical indices of the subarctic Shuonijavr Lake located in the zone of airborne pollution from a metallurgical plant have been considered. The following facts have been revealed: significant increase of alkalinity and acid n...
