Phytoremediation refers to a diverse collection of plant based technologies that use either naturally occurring or genetically engineered, plants to clean contaminated environments. Topsoil samples (20-50cm) were taken at various locations of landfill depot, the metals analyzed were Cr, Cu, Zi, Ni, Mn, Fe and Co. The results showed that, the percentage conc. of metals were Cu (72-73 %), Zn (8788 %), Cr (89-90 %) and Ni (87 %) showed higher in waste soil (WS) as compared to control soil (CS). The T. erecta grown in this soil during the 2 months period these plants have ability to accumulate more amounts of metals from waste dump soil. Data showed that this plant have a ability to absorb, stabilize, volatilize and extract Cu (90-95 %), Zn (70-72 %), Cr (74-75 %) and Ni (43-44 %) form WS. This data showed that the potential of plant for remediation it hyperaccumulate Cu > Cr > Zn from waste soil. Vigorous growth of Tagetus erecta has been observed in waste soil than control with respect to biomass production, chlorophyll contents and anatomy of plant.
