Anthropogenically Induced Processes in the Land Waters of the Arctic Regions

The characteristics of the development of anthropogenically induced processes in the land waters of the Arctic basin, such as eutrophication, acidification and toxic pollution in a changing climate, are characterized. The main changes in ecosystems and periods of occurrence of the most dangerous situations are shown. The criteria for diagnosing adverse processes and the need to tighten water quality standards for the waters of the Arctic regions are substantiated.
