| 内容記述 | Among alkaline earth elements, Mg and Ca are known as essential elements for plants, while Sr and Ra are of importance in radioactive waste management because of their long-lived radionuclides, including 90Sr and 226Ra. Use of chemical analogues for these radionuclides has been studied, i.e. Ca for Sr and Ba for Ra, because long-term behaviors of 90Sr and 226Ra are difficult to study in the laboratory. However, there are limitations to the use of different elements as analogues in some environmental systems. In this study, we focused on alkaline earth elements (Be, Mg, Ca, Sr, Ba and Ra) in soil-to-plant systems to learn how their uptake behaviors were correlated. Interestingly, concentrations of alkaline earth elements in leafy vegetables and river water were well correlated (r=0.99, p<0.001). Thus, not only selective uptake mechanisms of essential elements on the root surface strongly affect their uptake by plants, but also solubility of these elements affects this. By considering the mechanisms, we should be able to provide more practical values to estimate transfer factors of the radionuclides. | |||||
