Abstract
A set of trace metals (Si, Al, Fe, Mn, Sr, Ba, Rb, Co, Ni, V, Zn, Cd, Cu and Pb) was analysed in rainwater from Southern Sardinia. Crust-Poor Rain (CPR) and Crust-Rich Rain (CRR) groups of events were distinguished. The CPR EFcrust value of non-marine strontium (cSr), chosen as the new “cut-off” value, allowed to discriminate crustal metals (Al, Fe, Si, Rb, Mn, Co and Ba) from anthropogenic metals (Cu, Pb, Cd and Zn). The contents of crustal metals in rainwater increase in proportion to their solubility as a consequence of mineral dissolution, while Saharan dust appears to act as a “sink” for some anthropogenic metals in rainwater.
