The capacity of Lemna minor to remediate toxic heavy metals from wastewater is reasonably well documented. In view of the pivotal role of this species in the environmental clean-up, here we evaluated the bioaccumulation potential of L. minor for cadmium (Cd), lead (Pb), and nickel (Ni) through a controlled experiment. L. minor tolerated the metals Cd, Ni, and Pb up to 0.5, 5, and 8 mg/L, respectively, and beyond these concentrations the toxicity symptoms appeared. Bio-concentration factor varied at different concentrations of heavy metals tested. Overall, L. minor showed good phytoremediation potential for all the three tested heavy metals (Cd, Ni, and Pb), though in relative terms it was more effective in extracting Ni and Cd, as compared to Pb, both in single and mixed concentrations. In view of the growing pollution in Kashmir Himalayan aquatic habitats the phytoremediation by invasive species such as L. minor promises to be one of the best choices than other native plants for cleaning up of polluted soils/water because of its fast growth rate, high abundance, easy handling, and wide distribution in Kashmir Himalayan aquatic ecosystems.

Lemna minor 能够从废水中去除有毒重金属的能力 已有相当充分的文献记载。鉴于该物种在环境清洁中的关键作用，在这里我们 通过对照实验评估了小L. L.对镉（Cd），铅（Pb）和镍（Ni）的生物蓄积潜力 。微小 链霉菌分别耐受Cd，Ni和Pb高达0.5、5和8 mg / L的金属，超过这些浓度，会出现毒性症状。在不同的重金属浓度下，生物浓度因子会有所不同。总体而言，小L.对三种测试的重金属（Cd，Ni和Pb）均显示出良好的植物修复潜力，尽管相对而言，无论是单一浓度还是混合浓度，与Pb相比，它都能更有效地萃取Ni和Cd。鉴于克什米尔喜马拉雅水生栖息地的污染日益严重，由于其生长速度快，丰度高，通过诸如小L. L.等入侵物种进行的植物修复有望成为比其他本土植物清理污染土壤/水的最佳选择之一。克什米尔喜马拉雅水生生态系统中易于操作且易于分布。
