On the Accumulating Characteristics of Nuclide Cs in Chenopodium Album Linn, the Hyper-Accumulator Plant

Abstract:

Studying and screening nuclide hyper-accumulator plants and their planting methods for rapid and effective radioactive decontamination in the environment is the vital study content of the environmental radioactive contamination rehabilitation and control. This study measures and analyzes the accumulating amount and characteristics of Cs in Chenopodium album Linn by taking Chenopodium album Linn as the experimental material and CsCl solutions at different concentrations as the treatment factors, and applying the technology of pot culture to simulate the natural contaminate environment with radioactive nuclide Cs. The results indicate that the accumulating amount of Cs in Chenopodium album Linn increases as the CsCl concentration rises. The accumulating amount in the above-ground plant parts reaches the highest level of 0.964mg/g DW as the CsCl concentration reaches its highest one of 100mg/Kg; and that in the underground counterparts is 0.306mg/g DW. The accumulating amount of S (of the above-ground plant parts) /R (of the underground counterparts) > 1, having the basic characteristics of Cs hyper-accumulator plants.
