Abstract
This study was to assess the Phytoextraction of Acalypha inferno for Zinc (Zn) contaminated soil. Stems were planted in five kilograms (5 kg) of the soil placed in each plastic pot having 0 ppm (control), 5, 10, 15, 20 and 25 ppm of Zn. The experiment was on for a period of 12 weeks. The results revealed that pH, phosphorous and moisture contents increased while nitrogen and organic carbon contents decreased in polluted soil remediated with Acalypha inferno. The plant
compartments were analyzed for Zn uptake. Appreciable concentrations of Zn in different compartment of the plant was recorded, 7.12, 7.10 and 9.06 ppm for stem, root and leave, respectively. Bioconcentration Factor (BCF) and Translocation Factor (TF) was assessed. It was observed that more concentration of Zn was translocated from the roots to the leaves. The results obtained suggest that Acalypha inferno have phytoextraction ability and could be used in restoring
soil polluted with zinc (Zn).
