Abstract
In order to elucidate the cause for the leaching of iodine in a flooded paddy field, we investigated the transformation of an iodine species affected by the water management of the paddy field. The increased concentration of iodide (I −) in soil solution of a flooded paddy field suggested that I − was leached from the soil under anaerobic conditions. The post-edge feature of X-ray absorption near-edge structure (XANES) for iodate (IO 3 −) spiked to soil totally disappeared after anaerobic incubation of the soils, and I − was dissolved in the solution. On the other hand, I − in contact with the soil was not likely to be oxidized to IO 3 − under aerobic incubation. Iodine was leached out in soil solution as I − under anaerobic conditions, whereas part of the iodine species was retained by soil as I 2 or organoiodine both under anaerobic and aerobic conditions.
