Аннотация: The concentrations of nutrients in water and the total concentrations of metals were determined in water and bottom sediments of four lakes in Ergaki Ridge, which differ in their geographic, morphometric, and hydrophysical characteristics. By the concentration of all examined metals in water and bottom sediments, the lakes can be divided into two groups. The first group includes lakes Oiskoe and Svetloe, which feature large size and depth, while the second group includes small and shallow lakes Raduzhnoe and Karovoe. The concentrations of metals are compared with data obtained for different lakes of other mountain regions and with standards established for their concentrations in water and sediments. The concentrations of Zn and Cu in the sediments of Lake Svetloe were found to exceed the threshold, introduced by international standards, below which no impact on biota is recorded.
