Determination of heavy metals and lead strontium isotope characterization from Merlot soil samples, Dealu Bujorului vineyard

Abstract

Contamination of vineyard soils with heavy-metals has been a worldwide concern, determination of these elements it is important for the wine industry. The aim of this research was to determine the concentration of different heavy metals (Cd, Pb, U, Hg, As, Sr, Co, Cu, Ni and Cr) from vineyard soil on different depths in an area of vineyard cultivation from Dealu Bujorului Galati County. In order to highlight the combination of different sources, natural or anthropogenic of heavy metals the isotopic ratios for 206 Pb/ 207 Pb, 208 Pb/ 206 Pb, 206 Pb/ 207 Pb and 87 Sr/ 86 Sr from soil were established. The highest concentrations for heavy metals were recorded on the surface, with increasing depth of the soil these concentrations decrease. Regarding of Pb sources (lithogenic or anthropogenic), the average 206 Pb/ 207 Pb, 208 Pb/ 206 Pb and 206 Pb/ 204 Pb ratios in soil profile increase horizons followed the order: 1.13526

Elemental Content and Lead-Strontium Isotope Characterization of Wine

“…Other researchers have attributed the lead in wine to machinery or additives used during the winemaking process where environmental contamination in this case is low [29]. [30,31]. The winemaking process of red and white wines does not affect the 87 Sr/ 86 Sr ratio of wine, so this allows to link the Sr-isotopes of wine to those of the vineyard substratum [32,33].…”
