Trace elements in the spring waters of Moscow

Abstract

Data on the content of major ions (Na+, K+, Mg2+, Ca2+, Cl–, SO42–, HCO3–) and dissolved trace elements (Rb, Cs, Be, Sr, Ba, B, Si, Pmin, V, Cr, Ge, As, Mo, W, Sb, Te, Mn, Fe, Co, Ni, Cu, Zn, Cd, Ag, Sn, Pb, Al, Ga, Ti, Zr, U) in the waters of 30 springs in Moscow during the winter low water period are presented. The geometric mean values and ranges of concentration of the studied components, as well as correlations between them, were established. The presence of hydrochemical anomalies of dissolved iron and manganese in the north-east of Moscow with an excess of maximum allowable concentration (MAC) for these elements was revealed, whereas in the rest of the city their concentration almost everywhere correspond to the natural background.
