These plants are then transferred to the contaminated site to collect the contaminants and once the root are saturated, they are harvested. Rhizofiltration allow in site treatment, minimizing disturbance to the environment. According to Boyd, (1998:181-201) Hyper accumulate Heavy metals (1) Heavy metal pollution of aqueous streams is a major environmental problem facing the modern world. Several methods of removing heavy metals form water based on ion exchange or chemical and microbiological precipitation have been developed and used with some success. (2) These technologies have different efficiencies for different metals and may be very costly if large volumes, low metal concentrations, and high cleanup standards are involved. Recently, there has been some research into the use of living and nonliving bacteria and algae for the bioremediation and recovery of heavy metals form aqueous streams. (3) In addition, live or dead cultured cells of Datura innoxia, a higher plant, can be used to remove Ba2+ from solution. FOR FULL MATERIAL CALL 08032849308 MR CHINEDU
