DETERMINATION OF TOXIC METALS IN MARINE BIO-MONITORS BY MULTIVARIATE ANALYSIS OF VOLTAMMETRIC AND SPECTROSCOPIC DATA. APPLICATION TO MUSSELS, ALGAE AND FISHES OF THE NORTHERN ADRIATIC SEA

none4noAn analytical procedure regarding the sequen¬tial voltammetric determination of mercury(II), cop¬per(II), lead(II), cadmium(II) and zinc(II) at trace levels by square wave anodic stripping voltammetry is proposed, and validated by standard reference materials through comparison with spectroscopic analytical methods. The validated analytical procedure was trans¬ferred and applied to fishes, mussels, and algae as possible biological monitors. Five sampling sites were chosen, located in the Adriatic Sea (Italy) be¬tween the Goro Bay and the Ravenna Lagoon. Multivariate analysis of data by Principal compo¬nents analysis (PCA) and Soft Independent Models of Class Analogy (SIMCA) allowed to explore data: similarities among samples and correlation of varia¬bles was evidenced.embargoed_20181231Melucci, D.; Casolari, S.; de Laurentiis, F.; Locatelli, C.Melucci, D.; Casolari, S.; de Laurentiis, F.; Locatelli, C
