Livia Vittori Antisari, Serena Carbone, Chiara Ferronato, Andrea Simoni & Gilmo Vianello
The aim of this work was to characterize dry atmospheric deposition after the washing of broad leaves and conifer foliage. To assess this method different sites chosen on the basis of different exposure to both point (e.g. waste incinerator plant (WIP), local crafts) and widespread (e.g. roads, agricultural practices) sources of anthropogenic pollution. The principal components analysis (PCA), performed on the major and trace elements identified after leaf washing, extracted four factors. F2 was lithogenic...
