Abstract

The long-term use of copper in viticulture has caused great copper accumulation in vineyard soils, resulting in negative effects on the environment through toxicity to aquatic and soil organisms. The aim of this study was to investigate the copper content in vineyard soils, grapes and wines from Dealu Bujorului, Murfatlar, Tarnave, Iasi and Ştefăneşti vineyards. The ICP-MS method was used for copper determination in vineyard soil, grape must and wine. Copper concentration in red wine samples was significantly higher than in the white wine samples. Values for Transfer Factor and Mobility Ratio indicates that Vitis vinifera L. does not allow the accumulation of copper from vineyard soil in must grape and wine. The copper concentration in grapes, must and wine has been influenced by the copper concentration in soils, by copper fungicide used to protect the vine and by other factors such as the biological specificity of cultivars during growth.
