| Research Abstract |
To clarify the behavior of PCPs in waters, this study investigated the paddy soil collected from the lower basin in Niigata, Japan, and considered the concentration and changes of PCPs in its sediment core. The analysis of sediment core confirmed the changes of PCPs in the last 60 years. It is clarified time and spatial distribution in the basin, and obtained the knowledge about behavior, such as a remains situation and half-life according to compounds. It was made clear that paddy fields and waters interact because matter moves around through water.
