Abstract:
The study presented in this article has been focused on developing a method for
elemental analysis of wine samples. A wide sample set of 200 wines contained white,
rosé and red still wines; the wine vintages being 2013, 2014, 2015, 2016, 2017 and
2019. Samples were taken from wine festivals in Pardubice and Hradec Králové and
private wineries in the Czech Republic. The analysis was performed using inductively
coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled
plasma mass spectrometry (ICP-MS); the determined elements being As, Ba, Ca, Cd,
Ce, Co, Cu, Dy, Er, Eu, Fe, Gd, Ho, K, La, Lu, Mg, Mn, Na, Nd, Ni, P, Pb, Pr, S, Sm,
Sr, Tb, Tm, Y, Yb, and Zn. The data obtained were processed statistically and the Sr/Ba,
Sr/Ca and Sr/Mg ratios were determined as potential indicators for the identification
and classification of the wine origin. The existence of the so-called gadolinium anomaly
for selected wine samples was investigated as evidence of the presence of anthropogenic
gadolinium.
