Cd, Pb and Cu in spring waters of the Sibylline Mountains National Park (Central Italy), determined by square wave anodic stripping voltammetry
Department of Life and Environmental Sciences, Università Politecnica delle Marche, Ancona 60131, ITALY
Square wave anodic stripping voltammetry (SWASV) was used to determine Cd, Pb and Cu in spring waters of the Sibylline Mountains National Park, Central Italy. Samples were collected from three different areas of the Park (Mount Bove North, Mount Bove South and Springs of River Nera) during the period 2004-2011. Physical-chemical parameters were also determined to obtain a general characterization of the waters. Very low metal concentrations were observed (i.e., Cd 1.3±0.4 ng L-1, Pb 13.8±5.6 ng L-1, Cu 157±95 ng L-1), well below the legal limits and also below the medians of known Italian and European data. Comparing the three areas it was noted that waters from the area of the Nera Springs are the poorest in heavy metals and the richest in minerals, that conversely the waters of Mt. Bove North are the richest in heavy metals and the poorest in mineral salts, and finally that intermediate values both for heavy metals and mineral salts were observed for the waters of Mt. Bove South.
Key words: Heavy metals / Cd / Pb / Cu / spring waters / voltammetry
