Abstract: Geochemical comparison between some metals (As, Cd, Cu, Pb, Se, V, Zn) emissions from an active volcano (Mt. Etna) and a highly industrialized area (Salek Valley) showed some interesting similarities: in general, most of the elements emitted into the atmosphere do not return to the Earth's surface and are therefore dispersed into the environment. Exceptions for Salek Valley are Cd, which probably derives in large part from rock leaching, and in part As and Pb, which fall mostly as ash. Also, Etna's emissions are richer in Cd and Cu, whereas industrial emissions at Salek Valley are richer in V and Zn. All other metals have similar fluxes in the two types of emissions.
