中文摘要	Background and Aims Characteristically baseline levels of Sb in the environment are low, but problematic local elevation trends arise from anthropogenic activities such as mining and incineration. Arsenic (analog of Sb) accumulation by rice can be reduced by iron (Fe) plaque. A hydroponic experiment was conducted to investigate whether Fe plaque could reduce the uptake and translocation of different Sb species in different rice cultivars. Methods After Fe plaque on rice roots was induced in solution containing 0, 0.2, 0.4, 0.7, 1.2, 2.0 mM Fe2+ for 24 h, seedlings were transferred into nutrient solution with 20 mu M Sb(V) or Sb(III) for 3 d. Results About 60-80% (Sb(III) treatment) and 40-60% (Sb(V) treatment) of the total Sb accumulated in Fe plaque. There was a significant correlation between the concentrations of Sb and Fe on the root surface. A similar relationship was observed in roots and shoots. Cultivar (Jiahua 1) formed the most Fe plaque, had the highest Fe associated Sb sequestration but the lowest Sb concentration in the root interior. Conclusions Fe plaque may act as a 'buffer' for Sb (V) and Sb(III) in the rhizosphere, and cultivars played an important role in the different species Sb uptake and translocation.
