ABSTRACT

Phytoremediation appears as a very promising technology for the removal of metal pollutants from the soil. At present, the technology becomes commercially applied through the world. The present study determined the effect of heavy metal concentrations (Hg, Cd and As) in agriculture soils and in Lantena camera and Ipomea carnea. The experiments were conducted to find out useful plant species for removal of mercury, cadmium and arsenic form soil as a phytoremediation. These plant species were grown for 60 days with the treatment of Hg, Cd, And As (5 ppm). The higher concentration of Hg, Cd, and As were recorded in Lantena camera and Ipomea carnea. Result showed that concentration of Hg, Cd and as in soil and also in plants recorded above the permissible limit set by WHO. Based on the present investigation it has been suggested that Lantena camera and Ipomea carnea have better accumulation for Hg, Cd and may be used for phytoremediation.
