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 Pb-206/Pb-207, Pb-208/Pb-206, Pb-206/Pb-207 and Sr-87/Sr-86 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 Pb-206/Pb-207, Pb-208/Pb-206 and Pb-206/Pb-204 ratios in soil profile increase horizons followed the order: 1.13526 (0-10 cm Pb-206/Pb-207) > 1.13427 (10-20 cm Pb-206/Pb-207); 2.12626 (10-20 cm Pb-208/Pb-206) > 2.12472 (10-20 cm Pb-208/Pb-206) and 17.36201 (10-20 cm Pb-206/Pb-204) > 17.36128 (0-10 cm Pb-206/Pb-204). Statistically, in the case of Pb-206/Pb-207 and Pb-208/Pb-206 there are very significant differences between the analyzed variants while Pb-206/Pb-204 does not show any differences with in terms of distribution on the depth of the soil profile. Our results confirm that the Pb-207/Pb-206, Pb-208/Pb-206, Pb-204/Pb-206 and Sr-87/Sr-86 isotope ratio can be used to track the geographical origin of wine, discriminate between wine production regions, and be used to characterize wine terroirs for forensic purpose.
