Paper Title
From Nanotechnology to the Dynamics of Precaution: A Reformulation of the Technological Risk Theme

This communication is dealing with some of the nanotechnology social issues. It aims to show how the convergence of the risk issues (for work, environment, and consumption), initiated through the promotion of the nano products life cycle, comes up against previous risk management practices, which are still highly compartmentalized and lack appropriate procedures. It questions the very possibility of managing risks of nanomaterials, and it highlights how precaution could or must play a role in discussions between stakeholders.
