Influence of Lead and Cadmium Concentration on the Accumulation Capacity of <i>Panicum maximum</i>

The restoration of soils polluted by trace metals (Pb and Cd) phytoremediation is an innovative ecologically sustainable solution. objective the study was to develop a process phytoaccumulation in with species Panicum maximum. For this purpose, 30 buckets containing soil were used. These included six (06) per dose contamination Pb Cd (3 mg/kg 9 100 300 Pb) (6) uncontaminated (control). During period 90 days experimentation, concentrations plant biomass measured. Also, bioaccumulation (BF) translocation (TF) factors, mass taken up determined. results showed that produced negatively influenced increasing concentration. accumulated P. maximum varied aboveground from 6.48 ± 0.55 18.09 0.71 (Pb100); 10.93 0.38 23.04 0.79 (Pb300); 0.91 0.02 1.50 0.03 (Cd3); 3.05 0.08 5.43 0.09 (Cd9) day 90. However, root biomass, ranged 8.09 0.58 22.57 0.86 29.45 0.49 62.35 0.82 0.66 0.01 1.11 0.07 2.22 3, 97 (Cd9), concentrated biomass.
