Overview
ABSTRACT
Although nanothechnologies, just like any scientific and technological evolution, represent considerable progress, their expansion is also able to generate new risks that must be prevented. This article reviews the main sources of manufactured nanomaterials and the risks they present for human beings in the professional sphere. It is possible to define the categories of people at risk thanks to the information provided on detection and measurement, contamination modes and risk identification. This has generated a whole set of preventive and protective actions which must be implemented.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

INTRODUCTION
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.
