Abstract

Tlie results of a year's study in the Savona area (Italy) for dust deposition have been analyzed in order to characterize the emission sources. The contribution of the major pollutant sources have been determined by tracer metals and their enrichment factors. The selected metals are Cd, Cu, Pb, An, Cr and Ni. The obtained results show four types of emission sources responsible for airborne trance metals: traffic, industrial plants, large oil coal fired power station, resuspension of soil particles and residential heating. 1 Introduction Many industrial processes are concerned with the production of dust aerosols, e.g. industrial plants burning oil, residential he
