NanoHarmony Will Hold Webinar in May in the “Improving the OECD Test Guidelines Process” Series
On May 4, 2022, NanoHarmony will hold a webinar in its series of webinars covering the different phases that an Organization for Economic Cooperation and Development (OECD) test guideline (TG) progresses through during its journey from a science-based initial idea through to use by industry to fulfill regulatory obligations. This webinar will cover phases 2 and 3 of the TG process, technical development and commenting and approval. Speakers will include: Chair Claus Svendsen, United Kingdom...
On April 7, 2020, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “Carbon Nanotubes — First nanomaterial of high concern on the SIN List.” As reported in our November 27, 2019, blog item, ChemSec added carbon nanotubes to the Substitute It Now (SIN) List in November 2019. According to Dr. Anna Lennquist, Senior Toxicologist, International Chemical Secretariat (ChemSec), ever since ChemSec created the SIN List, there have been...

ISO Publishes Standard Specifying Characteristics and Measurement Methods for Air Filter Media Containing Polymeric Nanofibers
The International Organization for Standardization (ISO) has published standard ISO/TS 21237:2020, “Nanotechnologies — Air filter media containing polymeric nanofibres — Specification of characteristics and measurement methods.” According to ISO, in recent years, air filter media containing nanofibers have been commercialized and widely used by different industries due to their high filtration efficiency, along with a low pressure drop created by the slip flow effect. ISO...
The European Union (EU) Observatory for Nanomaterials (EUON) posted an article on April 6, 2020, announcing the availability of a study that found a lack of data on female fertility. The study, A critical review of studies on the reproductive and developmental toxicity of nanomaterials, was commissioned by the European Chemicals Agency (ECHA) and carried out by DHI A/S and the Danish National Research Center for the Working Environment. The scope of this project was to...

National Academies Publish Quadrennial Review of NNI
The National Academies of Sciences, Engineering, and Medicine (National Academies) have published a prepublication copy of A Quadrennial Review of the National Nanotechnology Initiative: Nanoscience, Applications, and Commercialization. The National Nanotechnology Coordination Office (NNCO) asked the National Academies to form an ad hoc committee to conduct a quadrennial review of the National Nanotechnology Initiative (NNI) pursuant to the 2003 21st Century...
The National Institute for Occupational Safety and Health (NIOSH) has posted two posters from the NIOSH Nanotechnology Research Center (NTRC) on 3D printing: 3D Printing with Filaments: Health and Safety Questions to Ask and 3D Printing with Metal Powders: Health and Safety Questions to Ask. The posters provide health and safety questions with different control options and information intended to reduce exposure to potential hazards. The questions...
The U.S. Environmental Protection Agency published a proposed rule on April 1, 2020, that would amend the significant new use rules (SNUR) for certain chemical substances that were the subject of a premanufacture notice (PMN) and a significant new use notice (SNUN), including functionalized multi-walled carbon nanotubes (MWCNT) (generic). 85 Fed. Reg. 18173. This action would amend the SNURs to allow certain new uses reported in the SNUNs without additional notification...
