Abstract :
Wine is a complex matrix, which, besides water, alcohol and sugar contain a great variety of
components, organic as well as inorganic. Numerous studies have shown that a moderate consumption of
wine, especially red wine, improves health and enhance longevity when it is combined with a balanced
diet. Daily consumption of wine in moderate quantities contributes significantly to the requirements of
the human organism for essential elements such as: Ca, Mg, K, Cu, Mn, Mo, Ni, Se, Co, Fe, F, I and Zn.
On the other hand, several metals, such as As, Pb and Cd are known to be potentially toxic for human
organism. The present work is aimed to establish the metal content of wines from Dealul Bujorului
vineyard (S-E Romania) due to which we have not found information about the metal content of
Romanian wines (Dealul Bujorului vineyard) using ICP-MS method for the determination of metals
content from the published literature. The wine samples used in this experiment were obtained from the
wines produced from Fetească Albă, Italian Riesling and Şarba from the wine production of the years
2013, 2014 and 2015 at the Dealul Bujorului Vineyard. The wine samples resulted from micro-wine
production. Regarding the major elements in wine, Feteasca Albă variety has recorded the highest
concentrations (81.86±3.72 mg/L Ca [2014]; 153.29±3.03 mg/L Mg [2014]; 54.79±4.61 mg/L Na
[2014]), while the Șarba variety has recorded the highest concentrations of K (275.78±10.90 mg/L
[2014]) and Li (13.48±0.10 mg/L [2014]). In all tested wine samples, the toxic metals contents were
found in quantities below the limits imposed by legislation. Using the principal components analysis
(PCA) it was possible to group metals from wine according to their concentration, the significant variables
in relation to this separation being the K, Li, A, Ba, Cs, Sr, Co (PC1) and Na, V, La (PC2).
