Remediation of Radionuclide-Contaminated Sites Using Plant Litter Decomposition

摘要: Radionuclide contamination of ecosystems is a commonly known problem for many sites. A frequently used option in dealing with such phytoremediation. But when thinking phytoextraction measures, the process radionuclide enrichment plant material not terminated at end growing season, but may increase during decomposition litter afterwards. We show that be mostly important remediation radionuclide-contaminated sites both aquatic and terrestrial ecosystems. concentrations within organic soil/sediment layers strongly as well systems temperate zones although there are large differences. This attributed to emerging fixation where differences dependent on particular chemistry (e.g. redox chemistry) radionuclides. The potentially high accumulation developing matter soils/sediments aquatic/terrestrial ecosystem can easily removed from contaminated by removing matter. In summary, beside autochthonous processes phytoremediation), especially allochthonous decomposition) very
