Results concerning the levels and elemental compositions of daily PM10 samples collected at four air quality monitoringsites in Palermo (Italy) are presented. The highest mean value of PM10 concentrations (46 mgm 3, with a peak value of158 mgm 3) was recorded at the Di Blasi urban station, and the lowest at Boccadifalco station (25 mgm 3), considered as asub-urban background station. Seventeen elements (Al, As, Ba, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sb, Sr, U, V, Zn) weremeasured by ICP-MS. Al and Fe showed the highest concentrations, indicating the significant contribution of soil andresuspended mineral particles to atmospheric PM10. Ba, Cr, Cu, Mn, Mo, Ni, Pb, Sb, V and Zn had higher concentrationsat the three urban sampling sites than at the sub-urban background station. Besides soil-derived particles, an R-modecluster analysis revealed a group of elements, Mo, Cu, Cr, Sb and Zn, probably related to non-exhaust vehicle emission,and another group, consisting of Ba, As and Ni, which seemed to be associated both with exhaust emissions from roadtraffic, and other combustion processes such as incinerators or domestic heating plants. The results also suggest that Sb, orthe association Sb–Cu–Mo, offers a way of tracing road traffic emissions.
