Small but mighty

摘要

In 2004, a joint report published by the Royal Society and the Royal Academy of Engineering, Nanoscience and Nanotechnologies entitled Nanoscience and Nanotechnologies: Opportunities and Uncertainties warned that the risks of nanotoxicity were significantly serious as to warrant nanomaterials being assessed as new chemicals. It warned that the toxicity of nanoparticles cannot be predicted from the known properties of larger sized particles of the same substance and recommended that ingredients in the form of nanoparticles should undergo a full safety assessment by the relevant scientific advisory body before being permitted for use in products. It also recommended that products containing nanoscale ingredients should be clearly labelled, to enable people to make an informed decision about using such products".
