Pb isotopes and toxic metals in floodplain and stream sediments from the Volturno river basin, Italy

January 1, 2001

We present results of a stratigraphic and environmental geochemistry study of the eastern sector of the Volturno river basin (Italy) using stream sediment and floodplain drill core samples. The cores, dated back to 7,000 years B.P., have been used to evaluate background (baseline) values. Pb isotopic compositions and toxic metal abundances have been determined to discriminate natural versus anthropogenic sources. The Pb isotopic compositions of the stream sediments overlap the values of Pb in petrol. The results from both stream sediment and drill core samples plot along a mixing line between the field that characterizes the volcanic rocks outcropping in the area (the natural component) and the Pb isotopic composition of petrol used in western Europe. Results suggest a prevalent contribution of the natural component for the Pb in the drill core samples and a prevailing anthropogenic component for the Pb isotopic compositions in the active stream sediments samples.
