The purpose of the OECD Series on the Safety of Manufactured Nanomaterials is to provide up-to-date information on the OECD activities related to human health and environmental safety.
Physico-chemical properties for nanomaterials can differ from those commonly considered for non-nanomaterials challenging their risk assessment. The OECD developed tools to identify which test methods are (or are not) appropriate to measure a given physico-chemical parameter considered key to characterization and identification, for a given type of nanomaterial. Together, the Physical-Chemical Decision Framework to inform Decisions for Risk Assessment of Manufactured Nanomaterials and its Guiding Principles are collectively 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.
