Određivanje koncentracija elemenata rijetkih zemalja u tlu i maslačku (Taraxacum officinale)

A systematic research of the rare earth elements (REEs) concentrations in the environment of eastern Croatia or in the wider region has never been done, not even in the war affected areas. Using ICP-MS, rare earth elements (La, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm and Yb ) have been determined in Taraxacum officinale (dandelion). Samples of dandelion, an edible, wild plant used in human and animal nutrition, were collected at 42 locations in 11 settlements (two towns and nine villages). Rare earth element concentrations in the leaves of dandelion from 42 sites in eastern Croatia showed significantly higher concentrations in the plants from agricultural locations compared to those from nonagricultural (Mann Whitney test p=0, 0138). The resulting REEs concentrations in soils did not significantly differ from the European average [1]. The parallel soil analyses showed that exposure of the dandelion samples to REEs through soil was generally low, thus at this point, other possible anthropogenic sources of REEs should be investigated.
