摘要

植物修复是一种用于去除和降解土壤和水中污染物的绿色新兴技术。本研究在铅污染水平低于WHO标准(12 mg/kg)和高于WHO标准(72 mg/kg)的土壤中种植了白刺草植物。3个月后,在原子吸收光谱(Perkin Elmer analyst 400)的帮助下,分析了根、叶和茎中铅金属的积累。两种处理的铅含量均显著降低。对照组(0.09 mg/kg和0.43 mg/kg) Pb水平分别下降3.6%和18.7%。结果表明,寻常草是一种很好的植物修复工具,可以去除土壤中的铅金属

Phytoremediation of Lead Contaminated Soil with the Help of Bambusa vulgaris
Phytoremediation is a green emerging technology used to remove and degrade pollutants from soil and water. In this study, plants of B. vulgaris were grown in the soils, which are artificially contaminated by lead below the WHO level (12 mg/kg) and above the WHO level (72 mg/kg). After 3 months, accumulations of the lead metal were analysed in roots, leaves, and stem with the help of Atomic Absorption Spectroscopy (Perkin Elmer analyst 400). Significant decrease in level of Pb has been noted in both the treatments. Decrease in Pb level was 3.6% and 18.7% of control (0.09 and 0.43 mg/kg). It was concluded that the plant B. vulgaris is a very good phytoremediation tool to remove Pb metal from the soil
