Phytoremediation is an emerging technology that employs the use of higher plants for the clean upt he contaminated environment, a cost-effective, environment-friendly. In this study, the role of puring( Codiaeumvarigatum ) plants as a potential phytoremediator to soils contaminated with lead (Pb) was investigated. A pot experiment was conducted for four and eight weeks to compare the biomass andlead content in root, stem and leaf by puring. The plant grew well exposed Plants that grow well are exposed to Pb with as much as 250 mg.kg −1 and 375 mg.kg −1 soil. The result presented here showed that root, stem and leaf biomassdecrease with increasing concentration and exposure time. Pb accumulation increases with increasing concentration and time of exposure. Pb accumulation in roots> stems> leaves. Bioaccumulation of factors is less than 1 while factor translocation is more than one. Metal tolerance index values range 95.545%to103.406%. This suggests that Codiaeumvarigatum was a candidate for phytoremediation of lead
