Redistribution behavior of C in acetate between rock and water have been examined in anaerated condition. In the presence of nitrate salt C prefer to transport in air.

Partitioning behavior of acetic C in sedimentary rock has been studied in anaerobic atomosphere condition. Addition of nitrate salt in the solution showed good correlation between increase of oncentration of C in air and decrease of concentration of nitate salts. These results suggest that respiration of nitrifying bacteria result in the transformation of C.

The sorption distribution coefficients of cesium and iodine onto the soil are studied. The batch sorption experiments were conducted onto the 24 specimens obtained from 11 sites (12 geoslicers) at each two different depth compartment. The experiments were based on the way standardized by Atomic Energy Society of Japan. The Kd values of cesium ranged from 1,000 to 100,000 ml/g, corresponding to the result that most of the cesium in the investigation sites are stayed in the surface of the ground. On the other hand, the Kd values of iodine ranged from 0.4 to 150 ml/g. It is likely that the difference of Kd values is affected by not only the chemical form of the elements between cesium and iodine, but also mineral composition, cation and anion exchange capacities, content of organic matter, and so on. This investigation initially focuses on varieties of soil, such as sandy or clayey soil, and soil colors.
