A new document on Important Issues on Risk Assessment of Manufactured Nanomaterials was published by OECD as part of a series on the Safety of Manufactured Nanomaterials.
The document provides the current practices, challenges and strategies for assessing risk of manufactured nanomaterials in circumstances where data is limited, and there is a necessity for more research on specific risk assessment issues. As such, the document presents an overview of the chemical risk assessment paradigm and describes how various member-countries have adapted existing regulatory frameworks to the assessment of nanomaterials. It also presents the state of science on nanomaterials risk assessment (as of May 2021), and highlights priorities for research toward specific risk assessment issues. The document is available here.
