| 内容記述 | It is important to know carbon-14 (C-14) transfer from the soil to the edible parts of crops, since C-14 transfer from radioactive waste disposal sites is expected. Using C-14 in radiotracer experiments would be the most suitable to obtain transfer factors (TFs), however, using radiotracers in open fields is nearly impossible. In this study, we estimated TF of carbon for several agricultural crops using stable carbon isotope ratios. The estimated average TF value for white rice was 0.11+/-0.04 and that for upland field crops (including leafy vegetables, fruit vegetables, root crops, tubers, legume, wheat and barley) was 1.0+/-0.6. The results showed that the estimated values agreed well with previous values for radish, 0.16-1.5, by Sheppard et al. (1991). Thus we concluded that the estimated values would be applicable for TF of C-14 in agricultural systems. | |||||
