| Popis: | Phytoremediation as a technique for cleaning soil contaminated with potentially toxic metals uses plants that can absorb them, and then translocate and accumulate them in above-ground parts. Its effectiveness depends on the selection of adequate plants. Therefore, this study aimed to investigate the potential of three wild herbaceous plant species (Holcus lanatus L., Agrostis alba L., and Eupatorium cannabinum L.) growing on mine tailings for phytoremediation applications. The content of selected metals in soil and plant samples was determined by flame atomic absorption spectrophotometer. The research results indicate that the content of Pb and Cu in the soil of the rhizosphere of the studied species was higher than their remediation values, after the exploitation of polymetallic ore (lead-zinc-copper), which made the tailings an ecological hazard. The species H. lanatus proved to be a good candidate for the phytoaccumulation of Cr, and the species A. alba of Ca, while the species E. cannabinum proved to be phytoaccumulator of all tested metals in the researched mine tailings. Potential for phytoextraction applications were shown by the species H. lanatus for Cd, Cu, Mg and Ni, and A. alba for Cd and Zn. |
