摘要

研究了改性粘土矿物和赤泥对芥菜生物产量和砷生物利用度的影响。施用粘土矿物和赤泥产品可提高芥菜的总生物量。在较高剂量(5.00 g/kg)下，铁膨润土处理土壤的植物总生物量最高(11.2 g/pot)。dmso膨润土(1.23 mg/kg)和fe膨润土(1.28 mg/kg)在5.00 g/kg剂量下对降低土壤中可提取砷浓度最有效。这些产品还有助于降低人类通过芥菜叶摄入砷的危害商值(0.20-0.08)。这意味着改良型膨润土和赤泥通过降低砷浓度来提高芥菜产量。

Immobilization of arsenic in soil using modified bentonite and red mud to reduce its bio-availability in Brassica juncea

The influence of modified clay mineral and red mud on biological yield and arsenic bioavailability to mustard were investigated. The total biomass of the mustard was increased by application of clay mineral and red mud products. At higher doses (5.00 g/kg), Fe-bentonite treated soil recorded the highest total plant biomass (11.2 g/pot). DMSO-bentonite (1.23 mg/kg) and Fe-bentonite (1.28 mg/kg) were proved to be most effective in reducing the extractable arsenic concentration in soil at the rate of 5.00 g/kg doses. These products also help in lowering the hazard quotient (0.20–0.08) values for human consumption of arsenic through mustard leaf. This means that modified types of bentonites and red mud boost mustard productivity by reducing arsenic concentration.
