Abstract
In the 2009 in some experimental sites in Veneto (Vicenza and Treviso Provinces) has been collected 36 samples of soils in order to define, through XRF analysis, the content (wt%) of major elements (Si, Ti, Al, Fe, Mn, Mg, Ca, Na, K, P) and the concentration (ppm) of trace elements (Ba, Ce, Co, Cr, La, Nb, Ni, Pb, Rb, Sr, Th, V, Y, Zn, Zr, Cu, Ga, Nd, S, Sc). Moreover on 4 samples of grape juices, 4 samples of wines (cultivars Fiano, Verdicchio, NeroD! Avola e Refosco p. r.) and 2 samples of grapes (NeroD! Avola e Refosco p. r.) has been determined, using ICP-MS technique, the concentration of the most important trace elements (Li, Be, B, Na, Al, K, Rb, Ca, Sr, Ba, Mg, Mn, Fe, V, Cr, Co, Ni, Cu, Zn, Ga, As, Se, Mo, Ag, Cd, Sb, Te, Hg, Tl, Pb, Bi, U). These analysis has been useful to define quality of wines and grapes, typical ratios of every soils considered and to identify the geochemical fingerprint in an area where climatic differences are slightly important to influence the assimilation dynamics. In this work has been defined the relationship between soil matrix and wines through the comparison of the heavy metals concentration. Also for the purposes of food security, for both provinces concerned, were performed in gamma spectrometry analysis to determine the levels of natural radionuclides (238U, 232Th and 40K) and 137Cs.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
