Bauxite wastewater creates soil contamination and produces toxic effects on human health such as respiratory and skin rash problems. In this study, we investigated the phytoremediation ability of Jatropha curcas to remove bauxite wastewater from soil. Pot experiments were conducted to investigate the bauxite wastewater on the phytoremediation potential of J. curcas grown in contaminated soils. J. curcas exhibited a significant increase in plant growth leaf, root activity, plant height, and plant shoot when grown in bauxite contaminated soils compared with J. curcas grown in uncontaminated soils after 30 d treatment. Under bauxite exposure, a higher aluminium removal (88.5%) was observed in soils planted with J. curcas than unplanted soils (39.6%). The bioconcentration factor was also found to be 5.62, indicating that J. curcas have great tolerance and hyperaccumulator of aluminium under high aluminium concentrations and are capable of phytoextraction of soil contaminated with bauxite wastewater.
铝土矿废水会造成土壤污染，并对人体健康产生毒性影响，如引发呼吸问题和皮疹。在本研究中，我们调查了麻疯树从土壤中去除铝土矿废水的植物修复能力。进行盆栽实验以研究铝土矿废水对生长在受污染土壤中的麻疯树植物修复潜力的影响。与在未受污染土壤中生长的麻疯树相比，经30天处理后，生长在铝土矿污染土壤中的麻疯树在叶片生长、根系活性、株高和地上部分等方面均有显著增加。在铝土矿暴露条件下，种植麻疯树的土壤中铝的去除率（88.5%）高于未种植土壤（39.6%）。生物富集系数也被发现为5.62，这表明麻疯树在高铝浓度下对铝具有很强的耐受性和超积累能力，并且能够对受铝土矿废水污染的土壤进行植物提取。
