Due to their size and form, nanomaterials have specific properties that significantly impact on the health hazards they present. To assess the possible regulatory implications of this, scientists at RIVM carried out a hypothetical registration of nanosilver under REACH (the European regulation on the Registration, Evaluation, Authorisation and Restriction of Chemicals), and found that the information required for REACH “is not sufficient to determine the specific properties of nanomaterials, nor to assess how these properties affect their behaviour and effects in humans and the environment”. Questions arose as to what extent the nanoform of a substance corresponds to its non-nanoscale counterpart, and also on whether current risk reduction measures and extrapolation methods in risk assessment, as established for conventional substances, are applicable to nanomaterials. A timely report as we approach a new decade.
