Abstract: | Marine surficial sediments, intertidal molluscs and reed leaves collected in the Bay of Follonica are slightly contaminated by Pb, Ni, Zn and Fe. The main pollution sources are the waste water and the atmospheric emission of industrial plants. Probably, the weathering of the pyrite deposits along the eastern coast of Elba Island and adsorption and coprecipitation with hydrous Fe-Mn oxides increase the trace metal concentrations in sediments from the Piombino Channel. Mussels and limpets are contaminated by Hg because of the higher background level of the northern Tyrrhenian Sea. |
