Trace metals in wine and vineyard environment in southern Ukraine

The study was focused on measuring the concentration levels of trace metals in the environment, vines and wine within the wine-growing region of Ukraine and comparing the findings to the data from well known wine-growing areas. Analysis was carried out of Cr, Cu, Ni, Pb and Zn in irrigation water, grape juice and wine, Cu, Pb and Zn in soil (pseudo-total and acid-soluble fractions) and Vitis vinifera L. in leaves and grapes. The accumulation levels of Cu and Zn from soil to leaves were significantly higher than from soil to grapes. Pb had lower potential to accumulate in aerial parts than Cu and Zn. Higher contents of Cu and Zn were observed in Muscat white grape juice compared to Chardonnay. The concentration levels of Zn and Cu were higher in wine than in juice. Trace metals were regulated by the soil composition and biological specificity of cultivars. The data obtained from the study area did not exceed the international limits.
