土壤体系对大气挥发性有机物的净化研究进展

Progresses on research of atmospheric volatile organic compounds purification by Soil system

土壤体系是大气挥发性有机物的一个汇,同时其中的有机质、水分、温度以及微生物等对挥发性有机物的净化具有较大的影响。本文综述了土壤体系对挥发性有机物的净化的研究进展以及挥发性有机物在土壤中提取和检测的方法。同时初步阐述了挥发性有机物在空气、土壤、植物等三者之间的关系。最后提出植物-土壤体系联合修复空气污染,通过筛选生长快、净化污染能力强的植物和土壤类型、理化性质、有机质含量高的土壤,对城市地区和工业园区等污染严重空气进行修复。

Soil system may act as sinks of volatile organic compounds （ VOCs ）and at the same time, such as organic matter, moisture,temperature and microorganism for purification of volatile organic compounds has a great influence. Research on volatile organic compounds purification by soil system are reviewed in this paper,and that can be used for determination of volatile organic compounds in the soil extraction and detection methods. The study also initial illustrate volatile organic compounds in air,soil,plants,such as the relationship between the three. Finally,the author pointed out that plant -soil system joint repair air pollution,to screen plant species which grow fast and effectively metabolized the ponution,and soil types, physical and chemical properties ,high organic matter content of soil,the urban areas and industrial park such as polluted air to repair.
