- Abstract
The goal of this research was to assess the potential of Sr and Pb composition and also isotopic signature of lead (207Pb/206Pb, 208Pb/206Pb and 204Pb/206Pb), strontium (87Sr/86Sr) of wines from Bujoru, Smuli and Oancea wine-growing centers from Dealu Bujorului vineyard. In this study 162 wine samples were investigated. The wine samples were obtained from micro-wine production under conditions of 2014-2016 from Dealu Bujorului vineyard. For all tested wine samples, the toxic metals contents were found in quantities below the limits established by legislation. The highest values were registered to wine obtained from Feteasca Neagra(2016) variety (0.74275±0.00261) from Smul?i wine-growing center, the lowest value of 87Sr/86Sr isotope ratio was recorded to wine obtained from Muscat Ottonel (2014) variety (0.70165±0.00058) Oancea wine-growing center. A possible explanation for the higher mean of 87Sr/86Sr isotopic ration for wine can be the mineral consistency of the vineyard soil and its different eco-climatic conditions. Regarding 206Pb/207Pb isotopic ratios, we can say that the analyzed wine samples show shows traces of pollution comes from cars (automobile emissions) (if 206Pb/207Pb=1.1000-1.1400 [automobile emissions]). The Pb isotope ratio from wines varies in range between 1.12305-1.18597 (206Pb/207Pb), 2.09404-2.14190 (208Pb/206Pb) and 17.21089-17.70857 (206Pb/204Pb) with average 1.15202 (206Pb/207Pb), 2.10878 (208Pb/206Pb) and 17.42240 (206Pb/204Pb). Heat map was discovered a separation of wine varieties for white of this red depending on elemental contents and 206Pb/207Pb, 208Pb/206Pb, 206Pb/204Pb, 87Sr/86Sr isotope ratios.
