Effect of Toxic Heavy Metal Contaminated Soil on an Ornamental Plant Georgina wild (Dahlia)
Phytoremediation is an emerging technology for cleaning up contaminated sites, which is cost effective, and has aesthetic advantages and long term applicability. The report suggests about the mobility, bioavaliability and plant response to the presence of soil heavy metals. A greenhouse experiment was conducted to determine the phytotoxic effect of heavy metals such as Ni and Pb on the growth of Georgina wild. The selected metals were dosed at various concentration ranging from 0.5, 1.0, 1.5, 2.0 mg/kg for nickel and 5.0, 10, 15, 20 mg/kg for lead separately in soil. The results revealed that as the concentration of heavy metal in soil increases, the overall length of plant decreases with respect to control.
