Soil polluted by heavy metals represent an important environmental problem due to the toxic effects of metals, their accumulations throughout the food chain and the additional risk of groundwater contamination.
Metal remediation through common physico-chemical techniques is expensive and unsuitable in the case of extensive and unsuitable in the case of extensive areas. Therefore biotechnological approaches have received a great deal of attention in recent years. Bioremediaton, as a way of natural attenuation, adds phytoremediation, the use of plants for reclamation and microbe(PSB) together as a strategy for either enhancing(PSB-assisted Phytoextraction) or reducing the bioavailability of metal contaminants in the soil, especially in the rhizosphere as well as accelerating plant biomass production and growth. |
