| 内容記述 | It is important to know carbon-14 (14C) transfer from the soil to the edible parts of crops, since 14C transfer from radioactive waste disposal sites is expected. Using 14C in radiotracer experiments would be the most suitable to obtain transfer factors (TFs), however, using radiotracers in open fields is nearly imossible. In this study, we estimated TF of C 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, and we concluded that the estimated values would be applicable for TF of 14C in agricultural systems. | |||||
