Accumulation of toxic contaminants and heavy metals in the environment is among the major problems causing pollution. They cause contamination of air, soil, and water. It ultimately leads to the development of hazardous effects on the humans and other organisms. They are quite difficult to recover from the environment. Traditionally those pollutants can be removed from the environment by physical, chemical, and biological methods of remediation. But it is a general observation that those methods are either tedious, time-consuming, or less effective. Hence, there is always a need for the innovative remediation technology. Nanotechnology seems to be a better answer for such questions. Due to their unique properties, nanomaterials are considered to be the ideal solution of remediation called as nanoremediation. Many studies have shown their potential for the effective remediation of toxic materials. However, with application of nanoremediation, the risk associated with their use also needs to be focused because nanoparticles have also been shown to be toxic to the component of the environment. The nanoparticles toxicity can also be reduced or controlled by some remedies, which can make the safe use of them for the sustainable nanoremediation.
