Phytoextraction可以提供一个有效的原位技术去除重金属污染土壤。本文中的研究报告进行评估的生长响应香根草属zizanioides在砷(As)受污染的土壤和清除的能力。工厂最近确定了宽容的最高浓度,有很大的潜力在医治受污染的土壤。这已经被证明了进行盆栽试验。与不同层次的土壤上升。0,500,1000,1500和2000毫克公斤是修改与乳制品等有机修正案浪费,菌根和生物肥料(固氮菌),另一组没有修正案也一直比较评估修正案对砷去除的影响。植物收获六个月后,他们的增长和积累“根与芽”的估计。这项研究的结果表明,植物表现出高耐毒性在土壤和正常生长达到高达500毫克公斤修改乳制品浪费时,菌根和固氮菌。工厂没有幸存下来在500毫克公斤没有修改。这表明,土壤改良剂调用更多的根系生长和增强phytoextraction过程相对于其他治疗方法。在更高浓度即1000、1500和2000毫克公斤和没有修改,工厂没有幸存下来。 The accumulation of As was much greater in roots (185.4 mg kg-1) than in shoots (100.6 mg kg-1). The As level in the polluted soil was reduced from 500 mg kg-1 to 214 mg kg-1 after six months. The removal of As level in the rhizosphere was found to be 57%. Microbial population was not affected in the As contaminated soil amended with dairy sludge, mycorrhizae and Azotobacter. These results indicate that Vetiveria zizanioides could possibly be used with success for removal of As from contaminated soils.
