Chemical fraction plays an influential role in solubility and potential bioavailability of heavy metals in soils. Seasonally flooding and iron reduction are significant environmental processes of paddy soil. They may influence the fractionation of cooper (Cu) in paddy soil. In this study, an anaerobic incubation experiment was conducted to simulate the anaerobic environment of flooded paddy soil....
The objective of this study was to investigate influences of microbial Fe(III) reduction on biogeochemical transformations of different heavy metals in flooded paddy soil. Anaerobic slurry incubation was adopted with amendment of Cr(VI), As(V) and Cu(II) at different concentrations levels, respectively. Results showed that Cr(VI) was reduced to Cr(III) by Fe(II) which was the product of microbial...
