.The Organization for Economic Cooperation and Development (OECD) has published for comment a draft study report entitled “Applicability of the key event based TG 442D for in vitro skin sensitisation testing of nanomaterials.” Switzerland conducted experimental work with selected nanomaterials using OECD Test Guideline (TG) 442D (KeratinoSensTM) and made a basic in vitro to in vivo correlation to outline the potential relevance of the results for prediction of skin sensitisation of...

On September 29, 2022, the U.S. Environmental Protection Agency (EPA) issued final significant new use rules (SNUR) under the Toxic Substances Control Act (TSCA) for certain chemical substances that were the subject of premanufacture notices (PMN), including multi-walled carbon nanotubes (MWCNT) (generic). 87 Fed. Reg. 58999. The SNUR requires persons who intend to manufacture (defined by statute to include import) or process the chemical substance identified generically as MWCNTs (PMN...

Gov4Nano, NANORIGO, and RiskGONE, three projects funded by the European Union (EU), are working together “to develop and establish a robust public policy framework for the use of nanomaterials based on scientific evidence supporting a clear understanding of risks, their assessment and management within wider societal considerations.” The projects are conducting a survey to understand better how the needs of different stakeholders can be addressed through the outputs of the...

The U.S. Food and Drug Administration (FDA) will hold the “FDA NanoDay Symposium 2022” on October 11, 2022.
