The generalization of data on the microelement composition of waters of small lakes of Western Siberia not subject to direct human impacts. For the 130 lakes of various natural zones from tundra to forest steppe by atomic emission analysis (ICP-MS) concentrations of 60 trace elements (Fe, Cr, Ni, Pb, Cu, Zn, Cd, Hg, Si, P, B, Mn, Ba, Sr, Li, Rb, As, V, Co, U, etc.). For each natural area calculated medians are the minimum and maximum concentrations of trace elements in lakes, all the trace elements are arranged in series in the reduction of their content in the waters of lakes respective zones. Found that the content of macroelements (Na, K, Ca, Mg) and most trace elements (Si, P, B, Mn, Ba, Sr, Zn, Cu, Li, Rb, As, V, Co, U) has the highest value in areas of southern taiga and forest steppe. The exceptions are iron and aluminum concentrations are higher in the swampy waters tundra and northern taiga zones, characterized by high color and acidity. In addition to Fe and Al to Ti, Ni and Bi highest concentrations are also found in northern lakes. The data obtained can be used as background values in the evaluation of anthropogenic impacts on aquatic ecosystems of Western Siberia.
