High efficiency phytoextraction of uranium using L. Nash.

Uranium uptake, translocation and its effects on leaf anatomy in vetiver grass ( L. Nash) grown in hydroponics were investigated at a wide range of concentrations. At concentrations below 200 ppm (1, 5, 25, 100, and 200 ppm) almost 90-95% of uranium was depleted from the medium within 3 days of treatment, while at other concentrations viz.
