Antimonio, Selenio, Cobalto e Bario : Il Lago Maggiore, Trent'anni di Storia attraverso l'Analisi dei Sedimenti Superficiali

Sediments represent a primary importance because they are the memory of a catchment basin. The two areas investigated for evaluating spatial-temporal distribution of concentrations of four micropollutants: Pallanza Bay (8.4 km2) and the south of the Lake Maggiore (4.2 km2). The first area has suffered and still does from industrial contamination of Cu, Cr and Hg; the second area investigated represents the terminal peace of the south end Lake, the sediments describe the results of the total catchment basins. The work represents 21 sediment cors 16 cm depd, and divided in 4 cm. The age of samples has been investigated by analyzing 137 Cs, and the period of time showed is approximately 30 years, while the concentration of Ba, Sb, Se and Co has been determined by Neutron Activation Analysis.
