ECHA Updates Additional Guidance for Nanomaterials

On May 25, 2012, the European Chemicals Agency (ECHA) published three new appendices, updating Chapters R.8, R.10, and R.14 of the Guidance on Information Requirements and Chemical Safety Assessment.  ECHA updated the guidance based on the outcome of the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) Implementation Projects on Nanomaterials (RIP-oN) 3, which concerned aspects such as occupational exposure estimation and dose-response characterization for human health and for environment. According to ECHA, the updated appendices “will further enhance the advice to registrants of substances in the nanoform a full year in advance of the next REACH registration deadline,” May 31, 2013.
