Abstract

A MAJOR ENVIRONMENTAL CONCERN DUE TO DISPERSAL OF INDUSTRIAL AND URBAN WASTES GENERATED BY HUMAN ACTIVITIES IS THE CONTAMINATION OF SOIL. HEAVY METALS ARE THE MOST PREVALENT POLLUTANTS. IN RECENT YEARS, CONTAMINATION OF SOILS BY HEAVY METALS HAS BEEN INCREASED. AS A RESULT, IT HAS CAUSED ENVIRONMENTAL AND HEALTH PROBLEMS ALL AROUND THE WORLD. UNLIKE ORGANIC COMPOUNDS, METALS CANNOT BE DEGRADED, AND CLEANUP USUALLY REQUIRES THEIR REMOVAL. A WIDE RANGE OF PHYSICAL AND CHEMICAL PROCESSES IS AVAILABLE FOR THE REMOVAL OF HEAVY METALS FROM THE ENVIRONMENT. MOST OF THE CONVENTIONAL REMEDIAL TECHNOLOGIES ARE EXPENSIVE AND INHIBIT THE SOIL FERTILITY. THIS MAY CAUSE NEGATIVE IMPACTS ON THE ECOSYSTEM. PHYTOREMEDIATION IS A COST-EFFECTIVE, ENVIRONMENTAL FRIENDLY AND AESTHETICALLY PLEASING APPROACH. DIFFERENT SPECIES OF PLANTS CAN BE USED FOR REMOVING OF HEAVY METALS AS BIOABSORBENTS. PLANTS HAVE DIFFERENT MECHANISMS FOR PHYTOREMEDIATION INCLUDING RHIZOFILTERATION, PHYTOFIXATION, PHYTOVOLATILIZATION AND PHYTOEXTRACTION. HOWEVER, A LOT OF BIOMASS IS PRODUCED DURING THIS PROCESS AND IT NEEDS PROPER DISPOSAL AND MANAGEMENT. HIGH BIOMASS WEEDS CAN BE SELECTED TO RESTRICT THE PASSAGE OF CONTAMINANTS INTO THE FOOD CHAIN BY SELECTING NON-EDIBLE, DISEASE RESISTANT AND TOLERANT PLANTS, WHICH CAN PROVIDE RENEWABLE ENERGY.
