Determination of selected metallic ions in croatian white wines by ICP-OES method
Metallic ions take important place in enological practice. Usually all metallic ions are naturally present in wine in nontoxic level. Heavy metals (Pb, Cd, As, Hg) are toxic to biological systems because of their negative impact on physiological functions of cell. Maximum acceptable levels in wine have been established by the Office International de la Vigne et du Vin (OIV), while in Croatia maximum permissible levels are given by Official Gazette 2/05 and 16/05. The goal of this work was to determine the content of Al, As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sn and Zn, in 43 selected white wine samples from continental wine-growing region of the Republic of Croatia by ICP-OES method. Average values for each metal were 0.99 mg/L Al, 0.05 mg/L As, 0.0005 mg/L Cd, 0.0029 mg/L Co, 0.016 mg/L Cr, 0.18 mg/L Cu, 2.68 mg/L Fe, 1.25 mg/L Mn, 0.045 mg/L Ni, 0.046 mg/L Pb, mg/L 0.074 Sn and 0.716 mg/L Zn. The obtained results in all studied cases were lower than limits given by official regulation that indicates application of good vitiviniculture practice in that region.
