The present work regards the analysis of airborne pollutants emitted by an electric arc furnace steel making plant at a test site in Northern Italy and collected by conifer needles. The spatial and temporal trends of accumulation of Mn, Zn, Fe, Cr, Pb, polychlorinated dibenzo-p-dioxins/dibenzofurans and polychlorinated biphenyls dioxin revealed that the contribution from the steel making plant has never been particularly high, whereas traffic emerged as a significant pollution source. The benefits of combining bulk and single particle analysis in air pollution studies from different sources are also discussed.
