Trends in phytoremediation of radionuclides

摘要: Phytoremediation, a novel plant-based remediation technology, is applied to variety of radionuclide-contaminated sites all over the world. Phytoremediation defined as use green plants remove pollutants from environment or render them harmless. Current status several subsets phytoremediation radionuclides discussed: (a) phytoextraction, in which high biomass radionuclide-accumulating and appropriate soil amendments are used transport concentrate into above-ground shoots, harvested with conventional agricultural methods, (b) rhizofiltration, plant roots precipitate polluted effluents, (c) phytovolatilization, extract volatile volatilize foliage (d) phytostabilization, stabilize soils, thus rendering It shown that fast developing field might soon become an integral part management risk reduction process.
