Hydroponical estimation of interactions among selected heavy metals accumulated by Salix viminalis in phytoremediation process.
Determination of interactions between selected heavy metals (Cd, Co, Cr, Cu, Ni, Pb and Zn) in their phytoremediation by one-year-old cuttings of Salix viminalis 'Cannabina' was the purpose of this work. The achieved results indicate that Salix cuttings may successfully be used in phytoremediation of polluted soil and/or sewage not only with one metal at high concentrations but also in different combinations with the other metals. Under controlled conditions (the hydroponic experiment) new interactions were found as well as known data concerning interactions between-presented in the matrix-heavy metals, depending on whether their concentration and composition were confirmed. The results showed that the ratio of metal concentration can change the interaction intensity. The achieved results enable one to indirectly estimate the accumulation efficiency of dominating metals as well as accompanying ones at lower concentrations.
