Accumulation of heavy metals in different parts of Russian thistle (Salsola tragus, Chenopodiaceae), a potential hyperaccumulator plant species
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...

| Summary: | 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. |
