title: [Effect of Boron-antimony Interaction on the Uptake and Accumulation of Antimony and Boron by Rice Seedling].
abstract: Effect of interactions between boron (B) and antimony on the uptake and accumulation by rice (Oryza sativa L.) seedling was investigated in solution culture. The results showed that Sb(III) and Sb(V) could inhibit rice growth and Sb(III) was more toxic than Sb(V). Concentrations of B in rice roots and shoots were significantly affected by the addition of Sb(III) and Sb(V). The addition of 30 μmol x L(-1) Sb(III) could significantly decrease B of rice shoots and roots by 57.6% and 75.6%, and 30 μmol x L(-1) Sb(V) could decrease B of rice roots by 16.0%, compared with the control treatment, when the B concentration was 0.5 mg x L(-1). Equally, adding B also significantly affected the concentrations of Sb in rice roots and shoots. The addition of 2.0 mg x L(-1) B could decrease the concentrations of Sb in rice roots and shoots,by 39.1% and 9.2%, respectively, compared with 0.5 mg x L(-1) B, when the Sb(III) concentration was 10 μmol x L(-1). Adding 2.0 mg x L(-1) B could decreasd Sb concentrations in rice roots by 13.9%, compared with 0.5 mg x L(-1) B, when the Sb(V) concentration was 10 μmol x L(-1). Furthermore, adding B had significant effect on bioaccumulation factor and distribution ratio of Sb in rice roots and shoots. The results of the study demonstrated that Sb pollution in farmland could be alleviated by adding B fertilizer, thus protecting human health from Sb pollution.
