Determination of trace elements in Italian wines by means of total reflection X-ray fluorescence spectroscopy
Direct TXRF analysis of nine wine samples from Emilia Romagna region of Italy was performed in two different laboratories: Italy and Japan. Wine dehydration was also evaluated as sample conservation mean.
Traces of Fe, Cu, Zn and Pb are present in all the analysed samples, with concentrations lower than the limits established by the OIV. The target hazard quotients (THQs) were also calculated for seven elements (Cl, Mn, Fe, Ni, Cu, Zn and Sr) to determine their potential detrimental effects.
The results show that TXRF is a fast, simple and accurate analytical technique for trace element analysis of wine. Moreover, dehydration is an effective way to store wine samples for further elemental analysis.
