EMERGNANO: A review of completed and near completed environment, health and safety research on nanomaterials and nanotechnology. Defra Project CBO409

In this project we have carried out a detailed review and analysis of research carried out worldwide on Environment, Health and Safety aspects of engineered nanoparticles, (NP) including issues relating to hazard, exposure and risk assessment and regulation,and made an assessment of how far 18 of the ROs have been met and which gaps still remain to be filled (RO01, Nanotechnologies and public engagement, was specifically excluded from the contract). As far as practicable, we have carried out an appraisal of the research results with a view to highlighting any new information that may trigger a consideration for the need for regulation of nanomaterials, assessed the possibility of a qualitative risk assessment and considered whether there is sufficient information to invoke the precautionary principle for one or more nanomaterials. Finally, we have made recommendations for new research to fill gaps.
