Bioaccumulation of major and trace elements in leaves and grapes in a vineyard site of La Mancha region
Abstract
Three different plot soils in a vineyard were characterized. The soils belonged to the Luvisol and Cambisol groups. In each case, major and trace element contents were determined in topsoil, leaf and grape samples. Analyses were carried out by X-ray Fluorescence techniques. The Biological Absorption Coefficient (BAC) was calculated as the ratio between the concentration of the element in the leaf or grape and that in the soil. The results showed that in soils the elements with the highest concentrations were Si and Ca. Trace elements with the highest concentrations were Sr, Ba, Zr, Rb, Ce, V and Zn. Both leaves and grapes contained high levels of Zn, Ba and particularly Sr. The presence of Rb in grapes was also significant. The elements with the highest BAC levels were Sr, Cs and Zn in leaves and Zn and Sr in grapes. Trace elements Ce and Nd were found only in leaves while Na was found only in grapes.
