Variation of the Chemical Element Content in the Dealu Bujorului Vineyard Soil

The purpose of this study is to know better the concentration of chemical elements in the soil from Dealu Bujorului vineyard. The determination of the ten elements from the soil samples was performed using ICP-MS. The results showed diverse patterns of cadmium, lead, uranium, mercury, arsenic, strontium, cobalt, copper, nickel and chromium, all the elemental content studied were under the maximum limit admitted, except for copper (average 356.03 mg/kg while M.L.A. = 20 mg/kg)

Metal Concentrations of Red Wines in Southeast Romania

Daily consumption, wine contributes to the requirements of essential elements, such as Ca, Fe, Mn, Mo, Co, Cr, K, Ni, Se and Zn for humans. However, the presence of significant amount of heavy metal in wine may harm the health of consumers. The present work is aimed at establishing the heavy metal content in red wines from Dealu Bujorului vineyard using ICP-MS method for the determination of metals content. In this study 3 red wines obtained from ‘Băbească neagră’, ‘Negru Aromat’ and ‘Burgund Mare’ cultivars were investigated. The wine samples were obtained from micro-wine production under conditions of 2014, 2015, 2016 from Dealu Bujorului vineyard. The determination of 13 elements was performed with ICP-MS. The high level of Ca (64.81-62.49 mg/L), Mg (132.61-101.44 mg/L) and Fe were observed in the wine samples analysed. Heavy metals like As, Cd, U, Hg and Pb was found below acceptable limits. Concentration of Na (1 mg/L), Cu (1 mg/L), As (0.2 mg/L), Cd (0.01 mg/L), Zn (5 mg/L) and Pb (0.15 mg/L) metals in analysed wine samples were under Maximum Permissible Limits (MPL), respectively as published by the Organization of Vine and Wine. Calcium and magnesium were the most abundant elements in all investigated wine samples. Concentration of Na (1 mg/L), Cu (1 mg/L), As (0.2 mg/L), Cd (0.01 mg/L), Zn (5 mg/L) and Pb (0.15 mg/L) in analysed wine samples were under Maximum Permissible Limits (MPL), respectively as published by the Organization of Vine and Wine
