Uptake of 133Cs and 134Cs by Ceratophyllum demersum L. under field and greenhouse conditions
Original language description
The phytoremediation abilities of Hornwort (Ceratophyllum demersum L.) were tested under greenhouse and field conditions. Plants were exposed for 8, 16, and 24 days (greenhouse with stable isotope 133Cs), 8 days (field with 133Cs), and 8 days (climabox with radioactive isotope 134Cs). The plants were exposed to different concentration of stable Cs provided as CsCl (0,008, 0,033, 0,133, 0,267, 0,533, 0,800, 1,067, and 1,333 mM) and different activities of 134Cs (4,46, 4,46, 4,74, 4,64, 2,23 and 2,26 kBq). The results of the experiment revealed a significant effect (p is lower than 0,001) of exposure time on Cs uptake. The results showed highest average 133Cs removal rates of 11%, 17% and 19% for 8, 16, and 24 days, respectively, in the greenhouse, 10% for the 134Cs experiment, and 27% for the field experiment with 133Cs. The results indicated that increasing the length of exposure lowered the uptake ability, hence indicating that the plant has limited capacity for Cs removal. The accumulated amount of
