Trace Elements in the Spring Waters of Moscow

摘要

Data on the levels of major ions (Na+, K+, Mg2+, Ca2+, Cl-, SO42-, HCO3-) and dissolved trace elements (Rb, Cs, Be, Sr, Ba, B, Si, P-min, V, Cr, Ge, As, Mo, W, Sb, Te, Mn, Fe, Co, Ni, Cu, Zn, Cd, Ag, Sn, Pb, Al, Ga, Ti, Zr, and 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 northeast of Moscow with an excess of the maximum permissible concentration (MPC) for these elements was revealed, whereas in the rest of the city their concentrations corresponds to the natural background levels almost everywhere.
