The ICP-MS technique was used to determine elemental composition (Pb, Sr, Cd, Ni, Co, Cu, Ni, Hg, As, Cr and Mn) of wines (Muscat Ottonel, Fetească Albă, Fetească Regală, Fetească Neagră, Merlot and Cabernet Sauvignon) wines produced in 2015, 2016 and 2017 from Bujoru, Smulti and Oancea wine-growing centers from Dealu Bujorului Vineyard. For all tested wine samples, the toxic metals contents were found in quantities below the limits established by legislation. The average data shows that the red wines contain highest concentration of Cd (0.17 μg/L), while the content of Cd in white wines are 0.11 μg/L. The concentration of U was 0.25 μg/L in red wines and 0.24 μg/L in white wines, while the concentration of Hg was 0.24 μg/L in red wines and 0.20 μg/L in white wines. The mean contents of Ni, Cr and Mn were 312.32 μg/L, 526.19±2.63 μg/L and 0.59±0.08mg/L, respectively. The concentration for Cu ranged from 0.45±0.10 mg/L to 0.90±0.04 mg/L, the last value being close to the law limit (1 mg/L). The four samples [Merlot 0.82±0.07 mg/L Bujoru wine-growing center (2015), Feteasca Alba 0.83±0.05 mg/L Smulti wine-growing center (2015), Merlot 0.83±0.05 mg/L Smulti winegrowing center (2015) and Cabernet Sauvignon 0.83±0.08 mg/L Oancea winegrowing center (2015)] showed relatively high concentration of Cu. Reporting the obtained results [Cd average 0.13±0.02 μg/L (0.1mg/kg M.L.A. = Maximum Limit Allowed) Pb average 40.64±1.85 μg/L (0.15 mg/kg M.A.L); As average 11.87±1.37 μg/L (0.2 mg/kg M.A.L); Cu average 0.67±0.09 mg/L (1 mg/kg M.A.L) to national and international legislation we can say that the wine from a Research Station for Viticulture and Enology Targu Bujor, 65 G-ral Eremia Grigorescu Street, RO-805200, Galați Country Romania. b Babeş-Bolyai University, Faculty of Chemistry and Chemical Engineering, 11 Arany Janos Street, RO-400028, Cluj-Napoca, Romania. c University of Agricultural Sciences and Veterinary Medicine, Department of Horticulture and Landscaping, 3-5 Mănăștur Street, RO-400028, Cluj-Napoca, Romania. d Institute of Advanced Horticultural Research of Transylvania, 3-5 Mănăștur Street, RO-400028, Cluj-Napoca, Romania. * Corresponding author: boraflorindumitru@gmail.com A. DONICI, E. GAL, C. CIMPOIU, C. I. BUNEA, F. D. BORA 114 Dealu Bujorului vineyard falls within the limits set by the law. The content of potentially toxic elements such as Cd, Pb, U, Hg, As, Cu, Ni, Cr and Mn are lower than values found in literature, highlighting the safety and quality of the analysed Romanian wines.
