Outline of Final Research Achievements

The controlling factors of the initial high radiocesium concentration and the depuration delay in Sebastes cheni were clarified. The stable element analysis and two years radioactivity measurement in living fish demonstrated that the K and stable Cs concentration were higher than in those found in other species. Species specific slow radiocesium excretion was confirmed. Analyzed radiocesium concentrations in stomach content of fishes inhabiting the same bottom reefs exhibited that the specific cesium accumulation along food chain was not substantial. Strong sedentary of S. cheni was confirmed as the determining factor to elevate the initial radiocesium concentration that was caused by the exposure to early phase contaminated seawater. Simulated temporal levels and the measured concentrations in S. cheni and seawater showed that the radiocesium transfer between this species and the environment was verified as being the equilibrium state.

Academic Significance and Societal Importance of the Research Achievements

硬骨魚の淡水と海水環境での塩類代謝差異は知られているが、硬骨魚間での差はないと理解され、アルカリ金属であるセシウムについても同様と考えられてきた。しかしながら、福島事故後のシロメバルにおける放射性セシウム高濃度が、特異的な塩類代謝に起因することが明らかとなり、硬骨魚類の塩類代謝に種差があることがわかった。進化後期に分岐したフサカサゴ科魚類が、なぜ特異的塩類代謝形質を獲得するに至ったか、新たな生理・生化学的な命題となった。福島沿岸のシロメバルの種特異的なセシウム高濃度の科学的根拠と、浄化過程のメカニズムの解明結果は、福島事故後の収束状況や水産物安全性の正しい理解につながると期待される。
