PHYSICO STUDY OF PHYTOREMEDIATION POTENTIAL IN PORTULACA GRANDIFLORA (OFFICE TIME)

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 Portulaca Grandiflora (Office Time) has been used for phytoremediation. Experiments were conducted using Chemistry lab effluent
