| Outline of Final Research Achievements |
The study was conducted by three experiments using aquatic macropyte Eleocharis acicularis, such as ①hydroponic cultivation experiments in Cs-K solution, ②radioactive Cs concentration and Bioconcentration Factor (BCF) of native Eleocharis acicularis in Fukushima Prefecture, and ③field experiment in paddy field of Fukushima prefecture.As a result of this study, ①Maximum concentration of radiogenic Cs of Eleocharis acicularis is more than 1000mg/kg-DW and it is consistent with hyperaccumulator of Cs, ②Native Eleocharis acicularis shows maximum values for 2400 Bq/kg in the prefecture, and ③Eleocharios acicularis cultivated in the paddy field which Cs radioactive concentration is 6580 Bq/kg shows their average 1310 Bq/kg in 2012, and 782 Bq/kg in 2013.
Based on the above results, it was demonstrated that phytoremediation of radioactive Cs polluted soils by Eleocharis acicularis is convenient and one of effective techniques.
