Conclusion
Nanomaterials and human risks at the workstation

In 2007, knowledge of the potential risks associated with nanomaterials is still limited [31] . More research needs to be carried out into the impact of nanomaterials on public health, occupational health and the environment, with due regard for safety measures. Priority should be given to studies on the human effects of chronic exposure (inhalation in particular), and to studies on target organs after translocation. This will lead to a better understanding of the physiological and pathophysiological effects of nanomaterials (in vivo studies) and a better understanding of the cellular and molecular mechanisms of nanomaterial-cell interaction (in vitro). Data on ecotoxicity and the study of their persistence and fate in the environment will also be essential elements in risk analysis.
