| Abstract: | Purpose Successful phytoremediation depends mainly on the bioavailability of heavy metals in the soil. Recently, soil microbes possess
several mechanisms that are able to change metal bioavailability in the soil, which provides a new strategy for investigating
biogeochemical cycling of metals in contaminated soils. Three metal mines soils with elevated concentrations of Cd, Pb, and
Zn from China were applied in this column study to (1) evaluate the effects of metal tolerant bacterial inoculation (Burkholderia cepacia, accession number: AB051408) on metal release, (2) monitor the migration of metals in the rhizospheric horizon (0–20 cm),
and (3) investigate metal speciation and sequential fractions in soil. |
