    Multi-elemental analysis of wine samples using ICP-OES and ICP-MS methods. Anthropogenic gadolinium in wine
    (University of Pardubice, 2021) Mišíková, Frederika; Patočka, Jan; Krejčová, Anna; Adam, Martin
    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.

    Impacts of textile industry on the environment
    (University of Pardubice, 2021) Audrlická Vavrušová, Lenka; Zídková, Petra; Krejčová, Anna; Adam, Martin
    The fashion industry, as one of the biggest polluters of the environment, is facing the increasing pressure from the general public to change its trade policy. This article provides an overview on the effects that the production and processing of textile fibers, together with waste from production and as unsold goods, may have on the environment. The environmental problems associated with the acquisition of natural fibers, the production of synthetic fibers, their processing and the final treatment of textiles are described. The need for water and chemicals, as well as the generation of waste at various stages of textile production are discussed. Finally, contributions of the resultant products to the carbon footprint as an important parameter of life cycle assessment are also explained.
