On February 24, 2022, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “Are nanoplastics hazardous? The way forward to overcome the uncertainties of risk assessment” by Dr. Anita Jemec Kokalj and Dr. Dana Kühnel about defining the criteria to evaluate which properties of nanoplastics should be reported in future

As reported in our July 9, 2021, blog item, NanoHarmony aims to support the development of Organization for Economic Cooperation and Development (OECD) test guidelines (TG) and guidance documents (GD) for eight endpoints where nanomaterial-adapted test methods have been identified as a regulatory priority. To identify difficulties arising during the development process for TGs

The National Nanotechnology Initiative (NNI) will hold a webinar on “What We Know about NanoEHS: Building International Bridges” on March 1, 2022. NNI states that it has supported the emergence of an international community of collaborative researchers on the environmental, health, and safety aspects of nanomaterials (nanoEHS). According to NNI, “[b]y advancing

The European Commission (EC) notified the World Trade Organization (WTO) on February 11, 2022, of a draft amendment to the Cosmetics Regulation regarding the use of certain nanomaterials in cosmetics products. The EC states that the amendment is required to enact the prohibition to use in cosmetic products certain nanomaterials for which the Scientific Committee

On January 18, 2022, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “What does ‘Graphene’ really look like and why is it not ‘carbon nanotubes’” by Dr. Alberto Bianco, Dr. Maurizio Prato, and Dr. Kostas Kostarelos, of the Graphene Flagship, an EU research initiative, about graphene and why it

The Organization for Economic Cooperation and Development (OECD) published a February 2022 report entitled Important Issues on Risk Assessment of Manufactured Nanomaterials. The report provides the current practices, challenges, and strategies for assessing the risk of manufactured nanomaterials in circumstances where data are limited, and the report states that there is a necessity for

The European Chemicals Agency (ECHA) has published a January 2022 update to the Appendix for nanoforms applicable to the Guidance on Registration and Substance Identification (version 2.0). The main changes to the document include additional guidance on the joint submission of data, clarifications regarding the need for one data set per nanoform or set of

On January 21, 2022, the European Commission’s (EC) Scientific Committee on Health, Environmental and Emerging Risks (SCHEER) published a second statement on emerging health and environmental issues. SCHEER members have identified nine emerging issues in the non-food area as having a potential impact on human health and/or the environment in the future and have

The International Organization for Standardization (ISO) recently published ISO/TS 21357:2022, “Nanotechnologies — Evaluation of the mean size of nano-objects in liquid dispersions by static multiple light scattering (SMLS).” ISO states that the standard provides guidance and requirements for the determination of the mean (spherical) equivalent diameter of nano-objects (i.e., particles, droplets,
