Abstract
Instrumental neutron activation analysis is used to determine a content of 47
elements (Na, Mg, Al, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Ni, Co, Cu, Zn, As,
Se, Br, Rb, Sr, Zr, Mo, Ag, Cd, Sb, I, Ba, Cs, La, Ce, Nd, Sm, Eu, Gd, Tb,
Dy, Tm, Yb, Lu, Hf, Ta, W, Au, Hg, Th, and U) in mosses (Homolothecium sp.,
Hypnum cupressiforme Hedw., and Brachythecium mildeanum (Schimp.) Schimp.)
and lichen (Cladonia fimbriata (L.) Fr.) collected in three locations in
Eastern Serbia over years 2006-2010. Concentrations of six elements (Zr, Nd,
Gd, Tm, Yb, and Lu) in mosses in Serbia are measured for the first time. For
other elements, the obtained concentrations fall within the ranges reported
for mosses and lichens in Europe, but no declining trend in concentrations of
V, Cd, Cr, Zn, Ni, Fe, and Cu, that has been described in the literature, can
be inferred from our results. Factor analysis shows that terrigenous and
industrial components are the highest contributing factors to the elemental
composition and that the most polluted measurement site is in the vicinity of
a copper mining and smelting complex.
