| Research Abstract |
Ecological impact of aquatic ecosystem by chemicals in run-off water has been worried. Thus in this study, potential filter media for passive treatment of run-off were screened. As a consequence, hydrotalcite was selected. Then adsorption characteristics of Perfluorooctane sulfonate was evaluated. The effectiveness of passive treatment proposed in this study was demonstrated by full scale experiment conducted at first-flush treatment wetland which is actual passive treatment facility treating road run-off water in Kusatsu city of Shiga prefecture.
