有机污染物在土壤中老化行为的研究进展

Research progress in aging behaviors of soil organic pollutants

有机污染物在土壤中的老化行为是目前有机污染研究的一个热点问题。通过对其机理的研究,可以达到调控污染物的目的。本文介绍了有机污染物在土壤中的老化行为和国内外研究现状,指出老化的实质包括有机污染物在土壤中的慢吸附和锁定,总结了土壤性质、化合物性质和环境因素对老化的影响,同时介绍了老化的评价方法,并在此基础上提出了目前研究有机物在土壤老化过程中所存在的问题,并对老化行为的未来研究方向进行了展望。

The aging behaviors of soil organic pollutants have become a major concern, and the study of the aging mechanisms could help us to control the target pollutants in soils. This paper summarized the research process at home and abroad about the aging behaviors, their essence, and affecting factors of soil organic pollutants, introduced the evaluation methods of the aging, discussed the existing problems in related researches, and gave some suggestions on the further study.
