Note sulle capacità di biorisanamento da metalli pesanti in due filtratori mediterranei

The aim of the study is to compare the heavy metals bioremediation capacity of two Mediterranean filter-feeders: the sponge Ircinia sp. and the ascidian Styela plicata (Lesueur, 1823). The analytical measurements have been performed by applying the technique of anodic stripping voltammetry (ASV) and by using the innovative miniaturized bismuth-based sensor. The results confirm that both organisms show a remarkable heavy metals bioaccumulation capacity. Furthermore, it turned out that the sponge Ircinia sp. has greater bioremediation potential than S. plicata.
