Outline of Final Research Achievements

A nuclear accident occurred in 2011 at the Fukushima Dai-ichi nuclear power plant (F1NPP) in northeast Japan. High levels of 137Cs have been reported in ambient aerosols from some areas of Fukushima after a decade of the accident. Based on the chemical analyses of atmospheric aerosols collected from Namie-cho in Fukushima, we found an increased positive relationship of 137Cs and organic tracers (i.e., arabitol, mannitol and trehalose) of fungal spore origin in the nighttime samples compared to daytime samples. We proposed in this study a soil-to-air emission of 137Cs via biological processes of fungi under favorable meteorological conditions. We emphasize that emissions of 137Cs due to fungal activities via spore emissions in nighttime are more important than emission of higher plant activities in both spring and autumn.

Academic Significance and Societal Importance of the Research Achievements

本研究の結果は、申請者らが提案した作業仮説(菌類の胞子が土壌中に蓄積した放射性セシウムの大気への重要な放出源である）を強力に支持するものであり、自然界における137Csの地球化学的・大気化学的プロセスを明らかにした大きな成果であ る。特に、土壌中に蓄積した放射性核種は微生物的・地球生物学的プロセスによって大気中に再放出することを示した初めての成果である。また、本研究は、放 射性核種で汚染された土壌を取り除くことの重要性を示す科学的根拠を提供するものであり、社会的に大きな貢献をするものであり関連分野へのインパクトは大きいと判断できる。
