Nanotechnology and the Water Market: Applications and Health Effects

Abstract

Nanotechnology has enormous potential for creating cost-effective, simple, and efficient tools for addressing water-supply challenges while preventing the creation of potentially toxic byproducts. The success of these technologies using nanomaterials, however, will depend on whether the nanoparticles and fibers can be confined and isolated from human and environmental receptors and on assessments of the potential health and environmental risks if exposures do occur. To truly qualify as “green” technology, applications of nanotechnology will need to demonstrate that such exposures and potential concerns for health and environmental risk can be managed adequately. This paper describes some of these technologies, focusing on nanofiltration and disinfection, desalination, and environmental remediation, as well as implications to human health and the environment.
