Results on atmospheric deposition of 45 elements in Báb research sites using the moss biomonitoring technique are presented. Concentrations of Ag, Al, As, Au, Ba, Br, Ca, Cd, Ce, Cl, Co, Cr, Cs, Cu, Fe, Hf, Hg, I, In, K, La, Mg, Mn, Mo, N, Na, Ni, Pb, Rb, S, Sb, Sc, Se, Sm, Sr, Ta, Tb, Th, Ti, U, V, W, Yb, Zn, Zr in the 3 year old segments of Pleurozium schreberi, Hylocomium splendens and Dicranum sp. are discussed in a context of their limit values. In comparison to the median Norway values of heavy metal contents in moss the Slovak atmospheric deposition loads of the elements were found to be higher on average. We find out statistical important decrease (20−90%) of concentration Cd, Fe, Ni, Pb and Zn by comparison 1990−2005. During the same period elements such as Mn, and S increased by approximately 107−198%. The obtained data can be useful as a reference level for comparison with the future measurements of air pollution in the examined area and also too for biodiversity study.
