Assessment of the Accumulation Ability of Festuca rubra L. and Alyssum saxatile L. Tested on Soils Contaminated with Zn, Cd, Ni, Pb, Cr, and Cu

The contamination of soils with metals applies, in particular, to areas related industry, the mining raw materials and ores, transport, agriculture. Unlike organic materials, cannot degrade over time need be reduced, removed, or immobilized soil. One remediation methods for contaminated is phytoextraction, which uses plants’ ability accumulate their own tissues. Metals enter plant organism through roots are transported aboveground parts, where they accumulated. In this study, we evaluated phytoaccumulative abilities two species tested on from industrial different extents (Zn, Cd, Ni, Pb, Cr, Cu). research was conducted three years under conditions a pot experiment. order obtain four varying degrees metal contamination, areas, G1 (contaminated) G2 (uncontaminated), were mixed following ratios: 1:1, 1:3, 1:7, 1:9. phytoremediation process, Festuca rubra L. Alyssum saxatile tested. After analyzing results bioconcentration factor (BCF) plants, it noted that both plants accumulated Cd Zn more easily, followed by Cu, then Pb lesser extent. values factors correlated high mobility these elements compared other relatively easy uptake plants. has an L., confirmed BCF (0.764) transfer (TF) (3.5) (for 1:7 combination) values. calculated BCFs less than one all metals, allows us state not accumulator.
