Abstract
A study of mercury concentrations in the atmosphere, atmospheric aerosols and rainwater of a Mediterranean region is reported. The mercury geochemical anomalies of this region seem to contribute to the metal content in the atmosphere only in limited areas close to the individual point sources. The degassing of the earth's mantle is probably not the only important mercury production mechanism; other natural and anthropogenic sources could give substantial contributions. Mercury concentrations of the different atmospheric components studied were found to be of the same order of magnitude as those reported in the literature for Oceanic areas.
