Determination of selected metallic ions in Croatian white wines by ICP-OES method

Metallic ions take important place in enological practice, some of them are necessary for the correct course of the fermentation, they influence clarity, aroma and sensorial properties of wine, and are important for nutritional properties. Usually all metallic ions are naturally present in wine in nontoxic level. However, some of them (Pb, Zn, Sn, Hg) may occur in higher level as a result of agricultural treatments in vineyard. Must and wine due to their acidity are able to dissolve some of metals (Cu, Ni, Zn, Cr) from different winemaking equipments. 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) for Pb, Cd, As, Cu, Na, F, Br and B, while in Croatia, maximum permissible levels are given for Pb, Cd, As, Cu, Zn, Sn, Fe, Ni, Ag, St, Al, Cr, Na, F, Br and B, by official regulations (Official Gazette 2/05 ; 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 winegrowing region of the Republic of Croatia by ICP-OES. 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 which indicates application of good vitiviniculture practice in that region.
