Since the document, Risk Assessment of Manufactured Nanomaterials: Critical Issues, was initially presented at the 4th meeting of the WPMN in 2008, the WPMN Steering Group Six (SG6) has been developing it taking account of comments/ suggestions from worldwide experts. At the 9th meeting of the WPMN, the title of the document “Critical Issues” was replaced by “Important Issues”. The WPMN has recognised that there is important information/ issues in this document which assist when considering the risk assessment of nanomaterials.

This document aims at introducing in chapters 2 and 3 the current practices and challenges on risk assessment of manufactured nanomaterials as well as strategies for assessing risk in circumstances where data are limited (chapter 4). Finally, this document makes clear in chapter 5 the necessity of direct research toward specific risk assessment issues in concert with current efforts to develop basic data sets, thus supporting the work on-going in other Steering Groups on the OECD-WPMN in view of further development of methods, models, data, and tools for use by decision makers to develop a systematic and integrated picture of environment, health and safety impacts of nanomaterials production and use. however, it is not to be construed to imply scientific and/or policy endorsement of any specific risk assessment methods or models.
