The OECD has just published two Publications in the OECD Series on the Safety of Manufactured Nanomaterials. 

The publications are the 'Physical-Chemical Decision Framework to inform Decisions for Risk Assessment of Manufactured Nanomaterials'  and its 'Guiding Principles for measurements and reporting for nanomaterials: Physical Chemical Parameters'. They are intended to facilitate the identification of the most useful parameters and best available methods while maintaining rigour in data quality and reporting. Together they offer an approach to gather fit-for-purpose physico-chemical information to more fully understand the behaviour of nanomaterials in biotic and abiotic systems.

The two publications have been developed by the OECD Working Party on Manufactured Nanomaterials (WPMN) and in particular by The Netherlands, United States and BIAC, to which the NIA is a Member.

The OECD Series on the Safety of Manufactured Nanomaterials has over the years published 91 publications related to nanomaterial safety.
