The enrichment of some metals (Al, Mg, Na, K, Cu, Zn, Cd) in volcanic gases is measured by an emanation coefficient ɛx relating the amount of the element x in lavas and in aerosols. ɛx is determined in the volcanic emissions of Mount Etna (Sicily), with regard to that of 210Pb. The accuracy of the results is limited by the geochemical behavior of common lead compared to that of 210Pb. Concerning the most volatile species, it appears that practically all the volcanic aerosols are produced by evaporation followed by gas-to-particle conversion and the spattered fraction appears to be negligible.
