Nanomaterials and human risks at the workstation

Although nanotechnologies have certain benefits (for example, their use in medicine or in decontaminating polluted soil), all scientific and technological developments are likely to generate new risks. Nanotechnologies are one source of nanomaterials – nanometer-sized objects. Little is known today about the impact of nanomaterials on humans and the environment. Yet products manufactured by nanotechnology are increasingly present in our daily lives and workplaces.

This document lists the main sources of manufactured nanomaterials. Their description helps define the categories of people at risk, and reviews the current state of knowledge on the health and safety risks of nanoparticles. It provides information on concrete prevention and protection measures implemented or recommended in the context of occupational exposure. Finally, the main techniques used in nanometrology are listed.
