Sažetak
The mobility of rare earth elements (REEs) in water is low. However, natural (weathering processes) or human origins (the use of phosphate fertilizers) may lead to elevated concentrations of REEs in surface waters and groundwater. [1, 2]. This study presents the results of analyses of the concentration of rare earth elements (REEs) in drinking water in the three settlements: Vladislavci, Čepin, Dalj (water from wells) and towns: Osijek, and Našice (public water supply system) located in eastern Croatia. Concentration of 13 rare earth elements: La, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb and Lu in 67 water samples were analysed by inductively coupled plasma mass spectrometry (ICP-MS).Mean concentrations of the REEs in analysed water samples ranged over 2 orders of magnitude, from less than 0, 001 to 0, 055 µgL-1 . From all measured REEs, La and Ce had highest concentrations in most of the investigated locations. Analyzed water displayed variations with ∑REEs ranging from 0, 019 µgL-1 (Čepin), 0, 038 µgL-1 (Osijek) 0, 065 µgL-1 (Našice), 0, 090 µgL-1 (Vladislavci) to 0, 20 4 µgL-1 (Dalj). No significant difference in mean REEs concentrations between water samples from wells and municipal water was observed (Mann –Whitney test, p=0, 30).
