Distribuzione e speciazione di metalli in traccia nell'acqua di mare superficiale del bacino delle isole Eolie

Summary - The distribution and speciation of cadmium, lead and copper in the Eolian Basin (South Tyrrhenian Sea) was studied by analysis of surface sea water samples using anodic stripping voltammetry (DPASV). Samples were analyzed to determine the total metal content (after acid digestion), the metal distribution between free fraction (or ASVlabile, mainly ionic and inorganically complexed metal) and bound fraction (organically complexed metal). The complexing capacity of the water was also evaluated by determination of the content of strong organic ligands complexing metals and the related conditional stability constants.
