title: Comparison of metal concentrations in three species of mosses and metal freights in bulk precipitations.
abstract: Concentration of 25 trace metals in mosses ( Hylocomium splendens, Pleurozium schreberi and Hypnum cupressiforme) are compared with bulk deposition freights (Bergerhoff method) at 3 sites in Switzerland, one on the plateau, a second in the northern prealps and a third in the southern alps. The three moss species are interchangeable and the atmospheric background deposition can be estimated with sufficient accuracy for Ag, Al, As, Cd, Ce, Co, Cr, Cu, Fe, Ga, Ge, La, Li, Mo, Nb, Ni, Pb, Th, Ti, U, V, W, Y, Zn. For Hg this study does not give definite results. No seasonal differences in moss concentrations from spring to autumn can be shown.
