Bioremediation of Mined Waste Land | SpringerLink
Soil microbes and plants can be used for remediation of contaminated soils either directly or by making heavy metals bioavailable in the rhizosphere of plants. Such plants can accumulate 100 mg g -1 Cd and As; 1000 mg g-1 Co, Cu, Cr, and Ni; and 10,000 mg g -1 Pb, Mn, and Ni and translocate metals to harvestable parts.
