Determination of heavy metal in seawater and macroalgae of shorelines of Naples and Ischia Island, Italy.

In order to develop monitoring of heavy metals (Cd2+,Cu2+,Pb2+) contamination in marine environment as well as macroalgae we have carried out this work in the Gulf of Naples and in the coastal region of Ischia island. Heavy metals were measured using the ASV (Anodic Stripping Voltammetry) analytical method. This work has given us the chance to underline the link between the state of seawater influences and the state of sessile species on the collected samples. The analyses have highlighted the bioconcentration of metals in sessile organisms. [ABSTRACT FROM AUTHOR]
