土壤和地下水环境中纳米材料迁移的研究进展

Review on the transportation of nanomaterials in soil and groundwater environment

纳米材料具有特殊的理化性质,在各个领域被广泛使用,最终其不可避免进入地下环境(土壤和地下水环境的简称)中,具有潜在的环境污染风险,因而需要研究其在地下环境中的迁移行为。在收集查阅有关于地下环境中纳米材料迁移研究的基础上,对纳米材料的分类、地下环境中纳米材料迁移的机理、数学模拟方法以及影响迁移的相关因素进行了详细归纳和总结。在此基础上,对地下环境中纳米材料迁移的过程、机理以及模型等尚需深入研究的科学问题提出了展望。

Nanomaterials have special physical and chemical properties,which are widely used in various fields and in the end will enter the subsurface environment（ soil and groundwater environment） inevitably. Because of the potential environmental pollution risks of nanomaterials,their transportation in the subsurface environment need to be deeply studied. Based on the study of the transportation of nanomaterials in the subsurface environment,the classification of nanomaterials,the mechanism of nanomaterial transportation,the mathematical simulation and the related factors affecting the transportation are summarized in detail. The scientific questions which need further studying including the processes,mechanism and mathematical model of the transportation of nanomaterials in subsurface environment are then proposed.
