| Abstract: | Cadmium (Cd) contamination in soils is a serious problem for crop production in the world. Zero-valent iron (Fe(0)) is a reactive material with reducing power capable of stabilizing toxic elements in a solution. In the present study, we examined the effect of zero-valent iron (Fe(0)) application on Cd accumulation in rice plants growing in Cd-contaminated paddy soils. The Fe(0) application significantly decreased the Cd accumulation in the leaves and seeds of rice plants grown in Cd-contaminated soils. The form of Cd in soil was determined by sequential extraction. The Fe(0) application increased the free-oxides-occluded (less available) Cd content, and decreased the exchangeable and Fe-Mn-oxides-bound (more available) Cd content, in Cd-contaminated soils. |
