| Title | Trace metal measurements in atmosperic dreposition at three sites in Northern Italy |
| Abstract | During 2004, Al, As, B, Ba, Be, Cd, Co, Cr, Cu, Fe, Hg, Li, Mn, Ni, Pb, Pd, Pt, Rh, Se, Sb, Sr, Tl,V and Zn were analysed for atmospheric deposition at three sites in Northern Italy: Alpe Devero, a high mountain valley far from anthropogenic sources; Verbania Pallanza, an urban centre; Bellinzago, an industrialized area. Analyses were conducted using ICP-OES and ICP-MS (the latter was necessary for requisite accuracy of 13 of the 19 elements). The t-tests performed on the data
obtained for the ions and the metals at the three stations showed that Alpe Devero had the lowest
levels for ions. Verbania presented concentrations similar to Bellinzago. At the Alpine station the
concentrations of Ba, Fe and Sr show significant differences compared with Bellinzago. Of the
metals of widespread anthropogenic origin, Cd and Zn showed concentrations lower than those
measured at Verbania and Bellinzago.
The measured fluxes of some metals were in good agreement with the fluxes estimated by the
EMEP. |
