Abstract: Wide varieties of plants have exhibited a specific ability to accumulate metals from soil and waste water into the roots, stems, leaves, flower and seeds. This unique characteristic of plants is being exploited extensively to remove toxic metals from contaminated sites by employing locally growing wild plants that have high adaptation capabilities without extra care. This is an eco-friendly safe, cheap, effective and green technology in cleaning the ecosystem. This work is carried out to evaluate the metal uptake potential of the wild plant Ipomoea carnea, (Convolvulaceae) growing on contaminated site for Cd, Cr, Cu, Fe, Ni, Pb and Zn. The bio-concentration factor (BCF) and translocation factor (TF) are also evaluated to assess the bio-concentration of metals from soils in the roots, stem and leaves of the plants. Most of the BCF values were more than unity, except BCFRoot for Cr and BCFLeaf for Zn, Cr and Cd. The order of BCFRoot was Fe (4.38) > Zn (2.51) > Cu (2.44) > Pb (1.70) >Ni (1.38) > Cd (1.35) > Cr (0.52). The order of BCFStem was Fe (5.47) > Cu (3.30) > Ni (2.80) > Cd (2.46) >Zn (1.43) > Pb (1.31) > Cr (1.19), however the order of BCFLeaves was Cu (3.53) > Fe (1.36) > Pb ( 1.24) >Ni (1.14) > Zn 90.76) > Cr(0.63) > Cd (0.27). The observed order of Translocation of metal ions from roots to the stem of Ipomoea was found to be Cr (2.29) >Cd (1.97) > Cu (1.35) > Fe (1.27) Ni (1.22) >Pb (0.77) >Zn (0.57), and the order of translocation from stem to leaves was Cu (1.06) > Pb (0.95) > Zn (0.54) > Cr (0.53) > Ni (0.41) > Fe (0.25) > Cd (0.10). These results indicated that Ipomoea carnea exhibited considerable metal uptake potential for Cd, Cr, Cu, Fe, Ni, Pb and Zn in its roots as well as translocated these to above ground parts.
