Os nanomateriais e a questão ambiental

Abstract

Recebido em 16/1/09; aceito em 3/8/09; publicado na web em 21/1/10 NANOMATERIALS AND THE ENVIRONMENT. The increasing use of nanomaterials in several products in different areas such as electronics, cosmetics, food and drugs has attracted the attention of the scientific community due to unknown properties of these materials, such as the life cycle and the interaction with receptor organisms once they reach the environment. In this context, the present work shows an updated scenario of nanomaterials applications, characterization methods and toxicity evaluation, also addressing important aspects related to the development and application of nanotechnology under the environmental point of view.
