| 内容記述 | The selenium (Se) sorption behavior in Japanese soils was studied by radiotracer experiments. Soil/soil solution distribution coefficients (Kds) were obtained for 110 agricultural soil samples as an index of Se sorption level using 75Se as a tracer. The Kd values ranged from 4 to 1616 L kg-1, and their geometric mean was 219 L kg-1. Among the soil types, volcanic ash soils had higher Kd values. It is known that volcanic ash soils contain large amounts of active-aluminum (Al) and active-iron (Fe), and the active-Al and -Fe were considered to be the major adsorbents of Se. The primary adsorption mechanism of Se onto soil active-Al and -Fe has been regarded as ligand-exchange, which is the same adsorption mechanism for phosphate. Therefore, the effect of phosphate input on Se sorption behavior was also verified. | |||||
