Environ Sci Pollut Res 29, 43421–43434 (2022). https://doi.org/10.1007/s11356-021-18370-w | Journal: | Environmental Science and Pollution Research | Abstract: | The aim of this study was to determine the concentrations of potentially toxic elements in soil samples and plant tissues of Minuartia recurva and M. bulgarica, predominantly or exclusively calcifuge species. Biological concentration (BCs) and translocation factors (TFs) were used to evaluate their accumulation potential. Considerable differences were observed between M. recurva and M. bulgarica assessions in terms of accumulation strategies of potentially toxic elements (PTEs). In M. recurva, most of the elements analyzed (Mn, Cu, Zn, Cd, and Co) were transported to the shoot, whereas in M. bulgarica, these elements remained predominantly in the roots. The Cu concentrations in the shoot samples of M. recurva from an abandoned iron-copper mine at Mt. Kopaonik were clearly above the notional hyperaccumulation threshold, characterizing this species as a possible Cu hyperaccumulator. Additionally, strong accumulation potential for Cr, Ni, Zn, Pb, and Cd was observed in M. recurva assessions, but without significant accumulation due to the low concentrations of these elements in the soils. The strong accumulation capacity and the different strategies in tolerance to PTEs indicate a potential of the two species for an application in phytoremediation: M. recurva for phytoextraction and M. bulgarica for phytostabilization. |
