| Research Abstract |
A large amount of dioxins is stocked in paddy fields, river sediments and circumjacent soils of a solid waste incinerator. The author found the mild way of decomposing these dioxins almost completely using sunlight and hydrogen peroxide. This provides the clean environment for rice and fish production. This can also clean up heavily polluted river sediments and surrounding soils of a solid waste incinerator. In addition, It was made clear as a result of congener analysis that the reduction of the dioxins occurs by dechlorination.
