The concept of nanomaterial refers to a substance or group of substances on the nanometer scale where the components are atoms and/or molecules. Although there is not a broad consensus on a single definition of them yet, many countries committed to nanotechnology initiatives have already proposed a definition for nanomaterial. The need of a worldwide agreed and standardized definition is nowadays being discussed. It can be argued that this lack of consensus can obstruct the regulatory and normative enforcement, as well as the search for agreements and international standards. In this paper, a review is made based on the existing definitions of nanomaterial, their incorporation into the industry and the risk factors for occupational exposure to these agents. Finally, some recommendations are given in order to adopt criteria for evaluating the impact of nanomaterials on human health and the environment.

Palabras clave : nanomaterial; nanomaterial parameters; nanomaterials legislation; occupational health nanomaterials.
