Specific features of formation of microelement composition of Baksan river sources at summer flood period

The aim of this investigation was to examine the formation features of microelement composition of glacial rivers at their sources. The study was carried out during 2012 – 2015. Some regular trends of formation of river chemical composition were revealed on the basis of comparative analysis of 8 metals (Cd, Cr, Cu, Mn, Ni, Mo, Pb, Zn) concentrations in melted snow at different altitudes, in the streams flowing from the glacier and in subsurface water.
