摘要
介绍了国内外对土壤（尤其是城市污泥）中的多氯代二口恶口英（ＰＣＤＤｓ）的研究现状，包括：土壤中ＰＣＤＤｓ的来源、分布及迁移转化情况，其环境稳定性使污染的危害程度加重；ＰＣＤＤｓ在环境中的降解主要是光降解、微生物降解和化学降解。
The Status quo of researches home and abroad on the sources,
distributions,migration and transformation of PCDDs in soils (especially, sewage sludge) has been
introduced. The high environmental stability of PCDDs has intensified its seriousness of pollution
to the environment. PCDDs are mainly degraded by photolysis in the environment. Further studies
on biodegradation, chemical degradation and physical treatment of PCDDs are needed.
