Abstract
Inductively coupled plasma mass spectrometry (ICP-MS) was used to determine the concentrations of 54 elements in water of small rivers and lakes, meltwater of a glacier and snowfields, as well as 49 elements in bottom silts in the Akkem River basin. Physicochemical characteristics of water objects were studied. The chemistry of natural water and bottom silts reflects the metallogenic features of the composition of underlying ore-bearing rocks. Despite the presence of natural sources of heavy metals in the upper reaches of the Akkem River and its tributaries, the concentrations of toxic substances in the majority of the examined water objects do not exceed the values of MAC for drinking water.
期刊介绍：
Water Resources is a journal that publishes articles on the assessment of water resources, integrated water resource use, water quality, and environmental protection. The journal covers many areas of research, including prediction of variations in continental water resources and regime; hydrophysical, hydrodynamic, hydrochemical and hydrobiological processes, environmental aspects of water quality and protection; economic, social, and legal aspects of water-resource development; and experimental methods of studies.
