A tandem preconcentration method integrating chelating resin adsorption and La coprecipitation was applied to an analysis of Lake Baikal water by high-resolution ICP-MS. As a result, 56 elements were determined in Lake Baikal water: Ca, Na, Mg, K, Si, Sr, B, Li, Ba, P, Fe, Al, Mo, Zn, Mn, Rb, U, As, V, Cu, Pb, W, Y, Cs, Se, Cr, Ni, Ti, Sb, Zr, Sn, Co, Cd, Rh, Te, Hf, Nb, Ru, Ga, Sc, Th, Bi, and all-rare earth elements (all-REEs), except for Pm. The concentrations of these elements covered a range of nine orders of magnitude, from approximately 17 microg mL(-1) of Ca to less than 50 fg mL(-1) of Tm. The elemental concentrations in Lake Baikal water were compared with reference data.
