| 摘 要： | 从吸附、渗漏、光降解和生物降解等迁移转化途径入手，总结了多氯联苯(PCBs)、多环芳烃(PAHs)和多氯代二恶英(PCDDs／PCDFs)等难降解有机污染物在土壤中迁移、转化的研究进展，结合土壤污染发展的特点，把大气-水-土壤-生物作为一个有机整体来研究难降解有机污染物在不同环境界面上的迁移、转化规律是今后土壤中难降解有机污染物迁移转化的研究方向，加强污染物之间相互作用机理的研究和提高土壤中难降解有机污染物的降解速率与深度是需要进一步解决的关键问题。

| Abstract: | The latest researches on the migration and transformation of the organic contaminators that are difficult to degrade in soil, such as polychlorobiphenyls, polycyclic aromatic hydrocarbons and polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans, their adsorption, leakage, photolysis and biologic degradation etc. are summarized. It is considered that atmosphere, water, soil and biosphere should be taken as an integrated system for the study of the migration and transformation of those contaminators. The key problems are the interactive mechanism among the contaminators and the increase of their degradation velocity and depth. |
