Research status on soil and water pollution remediation and environmental impact of nanomaterials

Abstract

Nanomaterials are a new type of materials, which have been widely used in many fields. In the field of environmental governance and restoration, nanomaterials are highly concerned by scholars all over the world. Due to the small particle size, strong reducing ability, high surface activity and large specific surface area, nanomaterials have obvious advantages in the rehabilitation and treatment of contaminated soil and water. At the same time, due to the characteristics of small particle size, low solubility and weak degradation ability, nanomaterials will have adverse effects on the ecological environment. In this paper, through literature research, the application of nanomaterials in soil and water pollution remediation and treatment is summarized, and the repair mechanism and influencing factors are briefly described. At the same time, the impact of nanomaterials on ecological environment is also summarized. On this basis, this paper points out that further research on measures to reduce the impact of nanomaterials on ecological environment should be carried out in the aspects of soil and water pollution rehabilitation and treatment.
