Abstract

Maintaining and restoring the quality of air, water, and soil is an important task. Soil suffers from several types of contaminants, such as pesticides, polychlorinated hydrocarbons, dyes, heavy metals, and radioactive materials, from different sources. Numerous conventional methods are available with some drawbacks like being expensive, slow, less efficient etc. Nanotechnology promises a potential revolution in approaches to soil remediation. Wonderful chemical and physical properties of nanomaterials provide better options for their use in soil remediation. Different types of nanomaterials such as engineered nanomaterials (ENMs) can be used in various approaches, that is, bioremediation, enhancement of bioremediation and phytoremediation, and catalysis of soil remediation, which in an integrated manner may provide better remediation of contaminated soils as compared to conventional approaches. Use of such ENMs can act as specific remediation to different types of contaminants in soil.
