| 内容記述 | We investigated sorption behavior of Cs in Japanese agricultural soils with taking into account effects of chemical properties, soil organic matter, and competitive ions. Measurements of the soil-soil solution distribution coefficients (Kds) of Cs for 112 agricultural soil samples (50 paddy soil and 62 upland soil samples) collected throughout Japan were carried out using the batch sorption test. Then, for 22 selected agricultural soil samples, sequential extraction methods were carried out for determination of Ca-exchangeable and pyrophosphate-extractable fraction. K concentrations in these fractions were also measured. The Kds for all soil samples ranged from 270 to 35730 L kg-1 and upland soil samples had higher Kds than paddy soil samples (p < 0.05). The proportion of Ca-exchangeable Cs was high at lower Kds. Therefore, Cs may be more mobile in soils due to application of fertilizers such as lime. In addition, when estimating the competitive ion effect on Cs sorption in soils, more attention should be paid to non-ion-exchange sites for Cs sorption on soil organic matter because soil organic matter could provide sorption sites for Cs besides ion-exchange site. |
