This document follows on from a report published by the Working Party on Manufactured Nanomaterials (WPMN), entitled Important Issues on Risk Assessment of Manufactured Nanomaterials (ENV/JM/MONO(2012)8).
The report on Important Issues identified a range of issues which the WPMN considered important in risk assessment and which should be addressed in the future. However, not all of these important issues could be considered by the WPMN at the same time. For this reason, a survey was subsequently circulated to delegations of the WPMN with the aim of identifying those issues described in the report for which further guidance should be developed by the WPMN as a priority. This document summarises the survey results, the methodologies used to analyse the survey, and the identified priorities. These priorities will be the primary focus of projects pertaining to approaches for risk assessments of manufactured nanomaterials.
The remaining Important Issues will be considered as additional resources become available. The survey results indicate that the availability of experimental data on which guidance development is based differs greatly between the Important Issues - an observation that should be considered when designing research programmes.
The work to prepare this document was undertaken by steering group 6 (SG6) of the WPMN which
addresses risk assessment methodologies and approaches. It is being published under the responsibility of
the Joint Meeting of the Chemicals Committee and the Working Party on Chemicals, Pesticides and
Biotechnology, which has agreed that it be declassified and made available to the public.
