The European Chemicals Agency (ECHA) has today published three new appendices to chapters R.8, R.10 and R.14 of its Guidance on Information Requirements and Chemical Safety Assessment (IR & CSA). The amended documents are said to 'implement the parts of the project relevant to the Chemical Safety Assessment of nanomaterials (RIP-oN 3)', which were co-authored by the NIA.
According to the organisation's press release, the updates relate to aspects such as 'occupational exposure estimation, [and] dose-response characterisation for human health and for [the] environment'. ECHA states that these will 'further enhance the advice to registrants of substances in the nanoform a full year in advance of the next REACH registration deadline', which is on 31 May 2013.
This is the second update ECHA has issued in as many months, having previously amended chapters R.7a, R.7b and R.7c at the end of April 2012. This followed the organisation's announcement on 22 February 2012 that it would be making amendments to the Guidance on IR & CSA so as to 'reflect the outcomes of the European Commission's second and third REACH (Registration, Evaluation, Authorisation and Restriction of Chemical) Implementation Projects on Nanomaterials (RIP-oN 2 and RIP-oN 3)'.
