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.

大量的二恶英存在于水田、河流沉积物和固体废物焚烧厂周围的土壤中。作者发现了利用阳光和过氧化氢几乎完全分解这些二恶英的温和方法。这为稻米和鱼类的生产提供了清洁的环境。这也可以清理严重污染的河流沉积物和固体废物焚化炉周围的土壤。此外，同源物分析结果表明，二恶英的还原发生在脱氯过程中。
