Abstract:  The authors present the results of the lake biogeochemistry studies in the context of reduced releases from copper-nickel production and observed climate warming in the Kola Peninsula of Russia. They show the main changes in the lake hydrochemistry over the past 25 years (1998 to 2023). The development of man-made induced processes, such as eutrophication, acidification, and toxic metal pollution, is characterized under a changing climate. It is shown that aquatic systems evolve into a new state, distinct from natural indicators, as pollution decreases and climate warming influences. The authors substantiate criteria for diagnosing adverse processes in the waters of the Far North. 

Keywords: Arctic basin, land waters, eutrophication, acidification, toxic pollution, assessment criteria

Funding:  This work was carried out within the framework of a state assignment from the Vernadsky Institute of Geochemistry and Analytical Chemistry of the Russian Academy of Science.
