Nanotechnologies and nanoparticles represent a promising and fast-growing field. This is principally because a nanodimensional substance can have physical and chemical properties that are different from those of the same substance with larger dimensions. However, the present knowledge is not yet sufficient for the elaboration of nanospecific regulations. Many projects with the aim of completing the necessary scientific and technical basis for the assessment of nanotechnology related risks are under way. Under these circumstances closely relationship between the industries and government bodies is necessary to build up safety standards or regulations by all stakeholders constitute an appropriate tool for the protection of human health and the environment.
