| 内容記述 | Toxicity of REE to human beings is not clearly known because their environmental levels are low; however, industrial emissions of REE to the environment and application of REE to agricultural fields are increasing. It is necessary to clarify their paths to human beings, although knowledge of their fate in the environment is limited. In this presentation, We focused on transfer of REE, Th and U from paddy soil to rice grains. Their concentrations were low in rice grains, and the measured soil-to-rice grain transfer factors were in the order of 10-5 to 10-3. | |||||
