| 摘 要： | 土壤是承载有机污染物的重要介质，而光降解是降解土壤表层有机污染物的一种非常重要的非生物转化途径。研究土壤表层有机物的光降解对认识污染物土壤环境行为有非常重要的意义。20世纪90年代以来对土壤中有机污染物的光降解研究有了大量报道。本文阐述了土壤组成和质地、土壤湿度、土壤pH值和土壤厚度等因素对光解影响的研究现状；介绍了目前研究土壤光降解所采用的研究方法：土壤表层直接光解、土壤悬浮液光解、溶剂萃取与光降解联合处理，及其研究土壤光降解应用的动力模型；对不同农药和其它有机污染物在土壤中的光降解研究进行了综述，并对今后的研究作了展望。 |

| Abstract: | Soil is an important medium in which various organic pollutants can exist, while photodegradation is an effective abiotic transformation means for organic pollutants in surface soil. To better understand the environmental behaviors of soil - bound pollutants, it is meaningful to investigate the photodegradarion of organic pollutants in surface soil. Many researches on this aspect have been made since 1990s. This paper discussed the effects of soil factors, e. g., composition, texture, moisture, pH, and depth on photodegradation, and described the methods and dynamic models applied in photodegradation researches, e. g., direct photodegradation of organic compounds in surface soil, photodegradation of organic compounds in soil solution, and solvent washing and subsequent photodegradation. The photodegradation of pesticides and other organic pollutants in soil was also reviewed, and the prospects of future research were analyzed. |
| Keywords: | organic pollutants photodegradation surface soil model. |
