This study aims to assess the effective capacity of Panicum maximum accumulate cadmium (Cd), nickel (Ni) and lead (Pb). P. observed in a greenhouse was subjected 2 ppm Cd, 50 Ni, 100 Pb contaminated soil uncontaminated soil, for 120 days. Plant growth biomass produced concentration trace metals plant, bioaccumulation transfer factors, location potentially toxic elements tissues cells plant have been determined. Stem length by were higher on followed respectively those soil-contaminated Pb, Cd Ni. Bioaccumulation factors 8.93 (Pb), 8.47 3.37 (Cd). Ni more accumulated shoot (FT > 1), while concentrated root 1). is preferentially endodermis (roots) epidermis (leaves). As they are central cylinder roots conductive bundles leaves. At cellular level, mainly intracellular compartments leaves roots, strongly detected at cell walls.
