Phytoremediation of Pb and Ni Contaminated Soils Using Catharanthus roseus (L.)

Journal Title: Universal Journal of Environmental Research and Technology - Year 2013, Vol 3, Issue 4

Abstract

Phytoremediation is an emerging technology that uses various plants to degrade, extract, contain or immobilize contaminants from soil and water. Plants can help clean up many kinds of pollution including metals, pesticides, explosives and oil. This technology has been receiving attention as an innovative, cost-effective alternative to the more established treatment methods used at hazardous waste sites. Contaminated soils and waters pose a major environmental and human health problem. Oil refineries and chemical plants produce billions of gallons of contaminated wastewater each year. Soils may become contaminated by the accumulation of heavy metals and metalloids through emissions from the rapidly expanding industrial areas, mine tailings, disposal of high metal wastes, leaded gasoline and paints, land application of fertilizers, animal manures, sewage sludge, pesticides, waste water irrigation, coal combustion residues, spillage of petrochemicals and atmospheric deposition. In the present study Catharanthus roseus has been used for lead and nickel phytoremediation. Pot experiments were conducted using aqueous solutions of lead and nickel. The two metal solutions were added to the pots for a period of 60 days on alternate days. Accumulations of the heavy metals were analyzed after 20, 40 and 60 days in leaves, stem and roots by AAS. The results showed that lead and nickel highly accumulated by the roots than stem and leaves. It was concluded that the plant species was a good accumulator of lead and nickel.
