Engineered Nanomaterials in the Environment

Exposure assessment approaches for engineered nanomaterials.

Products based on nanotechnology are rapidly emerging in the marketplace, sometimes with little notice to consumers of their nanotechnology pedigree. This wide variety of nanotechnology products will result (in some cases) in unintentional human exposure to purposely engineered nanoscale materials via the dermal, inhalation, ingestion, and ocular pathways. Occupational, consumer, and environmen...

Limited Usefulness of In Vitro Toxicity Data in Hazard Identification of Nanomaterials

With the increasing use and development of engineered nanomaterials in electronics, pesticides, consumer products, and chemical and pharmaceutical industries, there is a growing concern about their potential risks to humans and the environment. The toxic effects of most nanomaterials have not been characterized, but it is generally believed that nanoparticles can have toxicological properties t...

Effects of Engineered Nanomaterials on Plants Growth: An Overview

Rapid development and wide applications of nanotechnology brought about a significant increment on the number of engineered nanomaterials (ENs) inevitably entering our living system. Plants comprise of a very important living component of the terrestrial ecosystem. Studies on the influence of engineered nanomaterials (carbon and metal/metal oxides based) on plant growth indicated that in the ex...

Influence of Matric Potential on Survival and Activity of Genetically Engineered Ralstonia eutropha H850Lr

Although the application of biodegradative genetically engineered micro organisms (GEMs) for bioremediation is very promising, the risks of their release should be assessed before their introduction into the environment. Lux-marked Ralstonia eutropha H850Lr (formerly Alcaligenes eutrophus H850Lr) was introduced into sterile and non-sterile soil microcosms at matric potentials ?2.11, ?30, ?750, ...
