Název v původním jazyce

Effect of nano zero-valent iron application on As, Cd, Pb, and Zn availability in the rhizosphere of metal(loid) contaminated soils

Popis výsledku v původním jazyce

The effects of nano zero-valent iron (nZVI) were investigated in terms of the immobilisation of As, Zn, Pb and Cd in two soil types and their potential uptake by plants using rhizobox experiments. Sunflower (Helianthus annuus L.) and ryegrass (Lolium perenne L.) were tested for As-rich and Zn-rich soil samples, respectively. The application of nZVI effectively lowered the uptake of all target risk elements into plant tissues. The behaviour of As corresponded to changes in Eh, while Zn and Cd showed to be mainly pH-dependent. Furthermore, the accumulation of the target risk elements in roots and the overall effect of nZVI transformations in the rhizosphere were verified and visualised by SEM/EDS. The following immobilising mechanisms were suggested: (i) sorption onto both existing and newly formed Fe (hydr)oxides, (ii) formation of secondary Fe-As phases, and (iii) sorption onto Mn (hydr)oxides.
