Distribution and accumulation of 10 heavy metals was observed in plant parts of species S. tragus, a native representative of Serbian flora. According to high bioaccumulation values (BAF), more than a half of the analyzed elements were bioaccumulated in roots, as well as in the aerial part of the plant. Translocation factor (TF) value was calculated, showing the ratio between the concentration of metals in roots and aerial parts of the plant. The results indicate that S. tragus may accumulate significant amounts of Cd, Co, Cr and Pb. Concentrations of some of the individual elements are shown to be statistically different depending on the sampled plant parts. Potential capacity of S. tragus for hyperaccumulation of heavy metals and possible utilization of this plant for phytoremediation is discussed.
