| Outline of Final Research Achievements |
In order to clarify actual states of environmental contamination by radioactive Cs and to evaluate a novel method of radioactive decontamination in farm lands using plant-microbe interactions, we carried out several field surveys at Nihonmatsu city in Fukushima prefecture. Major clay mineral distributing in Nihonmatsu was Vermiculite and we found organic acid induces to release Cs from the clay by X-ray diffraction. Regarding paddy ecosystem, tadpoles had higher 137Cs activity concentration. In several tributaries of Abukuma River, 137Cs activity concentrations of sediments had a seasonal change pattern. Furthermore, wild ducks had concentrated 137Cs into their testes and ovaries. Several varieties of Brassica species with PGPR showed increase of radioactive Cs uptake. Though Brassica species could not uptake 137Cs fixed into clay minerals, Brassica species applied with K-solubilizing bacteria producing organic acids promoted those uptake.
