Abstract—Nanotechnology is a multidisciplinary field that has gained significant momentum in recent years. Nanoparticles are the key players that have promised many benefits through their nano-enabled applications in multiple sectors. This review summarizes the use of nanomaterials such as zero valent iron (nZVI) and carbon nanotubes (CNT) in environmental cleanup like ground water remediation for drinking and reuse. There are, however, concerns regarding the potential risks associated with the use of nanomaterials to the environment and human health. An understanding of the relationship between the properties of nanoparticles and their in vivo effects would provide an effective strategy to tackle the deleterious effects.

Index Terms—Carbon Nanotube, Iron Nanoparticles, Nanoremediation, Toxicology.
