Trace elements in soil and mosses (Dicranoweisia crispula (Hredw.) Milde) by the road to Stelvio pass, Northern Italy Apls: A case of small scale pollution biomonitoring
AbstractThe moss species Dicranoweisia crispula for bioindication were collected together with soil along road to the second highest paved mountain pass (Passo dello Stelvio) in the Alps. The trace elements such as P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, As, Se, Rb, Sr, Zr, Mo, Sn, Sb, Ba and Pb were determined using the hand-held XRF spectrometer DELTA CLASSIC (USA). From principal component analysis we determined four main phenomena, which were then evaluated in the context of localisation by the road. Several phenomena were described which could be ubiquitous in mountain regions, such as transboundary emission and traffic pollution related to touristic pressure.
