Abstract
Published data and research results from the authors on the concentrations of dissolved trace elements (P, Si, Li, Rb, Cs, Sr, Ba, Mn, Fe, Co, Ni, Cu, Zn, Cd, Tl, Pb, Al, Ga, Y, Ti, Zr, Hf, Th, U, rare earth elements, B, F, V, Cr, Ge, As, Mo, W, and Sb) in the rivers discharging into the catchment areas of the White and Kara seas have been synthesized. The mean concentrations of the vast majority of trace elements are found to be not much different from the values of the global runoff, and only some of them (P, Fe, Zn, Cd, Y, Zr, B, and W for the rivers of the White Sea catchment area and Cs, Fe, Zn, and Cd for the rivers of the Kara Sea catchment area) differ threefold in concentrations. The lack of significant differences in the mean concentrations could be a result of their spatial variability smoothed out over the extent of large catchment areas.
