| Research Abstract |
Distribution of Perfluorinated compounds were investigated in water environment, air environment, soil, groundwater in Asian megacities (Da Nang city in VietNam, Bangkok city in Thailand, Naha city in Okinawa island, and Osaka city). As a result of batch experiments of adsorption, an effective ion exchange polymer which had about 3 times absorption ability of a granular active carbon for PFOA was found. This was effective in a continuous experiments for real industrial waste water. In addition to it, an effective decomposition condition by ultraviolet radiation was shown. As a result of investigations of aquatic plant Phragmitescommunis and sedimentation, accumulationof PFCAs in soil and absorption by aquatic plants were shown.
