中文摘要：

有机污染物对自然环境和生态健康造成严重的危害。有机污染物在土壤中的吸附一解吸行为直接影响其环境行为。自然条件下，有机污染物与土壤介质长时间相互作用会出现老化效应。老化导致土壤中有机污染物的吸附一解吸行为发生变化，从而对环境中有机污染物的归趋产生重要影响。有机污染物在环境介质中的老化有利有弊，深刻认识老化作用对准确评估有机污染物的生态环境健康效应有至关重要的作用。当前的研究工作主要集中于老化效应对吸附一解吸和生物有效性的影响，对环境修复中经常使用的工程材料如生物炭、黑碳等的老化效应还缺乏深入研究。本文总结了有机污染物在土壤中老化研究的主要进展，评述了土壤中有机污染物老化研究中存在的问题，并提出了进一步的工作建议。

英文摘要：

Organic pollutants have shown serious harmful effects on natural and ecological environments, sorption and desorption are of key processes which controlenvironmental behaviors of organic pollutants. Under natural con- ditions,aging effects are commonly found when organic pollutants have been sorbed by soils. Aging may cause re- markably different sorption-desorption behaviors of organic pollutants on soils and such plays an important role in fate and transportof organic pollutants in the natural environment. Aging of organic pollutants may have positive or negative impactsin term of environment risk assessments, such, understanding of underlying mechanisms and effects of agingplays a vital role for accurately assessing ecologic environment health. The current researches mainly fo- cused onaging impactson the sorption-desorption behaviors and the bioavailability, fewregarded aging effects onusing engineering materials, such as biochar and black carbon, to repair contaminatedenvironment sites. This paper sys- tematically summarized the research progresses of organic pollutants aging in soil, discussed some issues of the cur- rent researches, and presented suggests to the future studies.
