Abstract
Engineered nanomaterials are being used in increasing numbers of applications throughout the world. Multiple studies have shown the potential of nanomaterials to lead to adverse human health effects, although the impact on ecological systems has largely remained unexplored. Nanomaterials enter the environment through air, water, and soil. The benefits of nanotechnology to ecology include the use of nanomaterials such as titanium dioxide in water remediation, zero-valent iron in soil remediation, and selenium in mercury adsorption. However, the potential long-term effects of these and other nanomaterials on the environment are unknown. Research into the impact of these materials on ecological systems from the use and disposal of nanomaterials has been limited. This article describes the available literature on the impact of engineered nanomaterials on a variety of ecological systems, including microbial organisms, plants and soil, and aqueous species.
