| 内容記述 | The formation of insoluble Tc (>0.2 micrometer in size) in ponding water of paddy soil was investigated. The ponding water prepared by flooding with deionized water was collected at a one-week intervals during the 120 days of the experimental period. The collected sample was incubated with 3 kBq-1 TcO4- at 25 degree for 14 days. The mean value of relative amounts of insolubilized Tc was less than 0.6% of total Tc. This result suggested that flooding with deionized water was not effective for the formation of insoluble Tc. When the ponding water sample was incubated with TcO4- under anaerobic conditions, Tc was scarcely insolubilized. On the other hand, a significant fraction of the Tc was insolubilized in the ponding water sample supplemented with nutrients that promote bacterial activity. Also, the amount of insoluble Tc increased with time. From these results, it was concluded that the formation of insoluble Tc in the ponding water depends on enhanced bacterial activity rather than just anaerobic conditions. | |||||
