On June 3, 2021, the French Agency for Food, Environmental and Occupational Health and Safety (ANSES) published an interview with Aurélie Niaudet, who is in charge of assessing the risks associated with physical agents. Niaudet states that nanomaterials have novel properties that “are highly sought after and increasingly exploited, but can also induce specific types of behaviour when interacting with humans or the environment.” After the human body is exposed, “there is then the question...

ISO Guidance Specifies Characteristics and Measurement Methods for Antibacterial Silver Nanoparticles
The International Organization for Standardization (ISO) has published standard ISO/TS 20660:2019, “Nanotechnologies — Antibacterial silver nanoparticles — Specification of characteristics and measurement methods.” The standard provides guidance for the specification of characteristics and relevant measurement methods for silver nanoparticles in powder or colloidal forms that are intended for antibacterial applications in nanotechnology. ISO states that the standard is...
On May 31, 2021, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “Updating our language: why we should not paint all nanoforms with the same brush” by Chiara Venturini, Director General of the Nanotechnology Industries Association (NIA). Venturini reviews how the EU’s language has evolved. In 2011, the European Commission (EC) adopted a definition that describes a nanomaterial as a material at the nanoscale. In 2020, the EC amended Annex II of...
The European Chemicals Agency (ECHA), as part of the activities of the European Union (EU) Observatory for Nanomaterials (EUON), is conducting a stakeholder survey on the substances available as nanomaterials in the EU market. The survey includes a market study of the nanomaterials, including substances, uses, volumes, and key operators in the EU. According to EUON’s May 21, 2021, news item, the survey aims to provide an overview of the substances that are available as...
Registration has opened for a June 8, 2021, webinar held by the U.S. National Nanotechnology Initiative on “What We Know about NanoEHS: Human Health.” The webinar will feature experts from diverse disciplines who will share their perspectives on key findings on the effects of engineered nanomaterials on human health. Janet Carter, Senior Scientist, Occupational Safety and Health Administration (OSHA), will moderate. The panel will include: Leanne Gilbertson, Assistant...
The U.S. National Nanotechnology Initiative (NNI) will hold a webinar on June 2, 2021, on nanosensors for food and agriculture. NNI states that nanotechnology-enabled sensors (nanosensors) “are promising tools to advance precision agriculture and support a safe and robust food supply chain, from farm to fork.” Panelists will discuss how the development and deployment of nanosensors could transform agriculture and food safety. They will highlight the state of the science,...

NIOSH CIB on Health Effect of Occupational Exposure to Silver Nanomaterials Includes REL for Silver Nanomaterials
The National Institute for Occupational Safety and Health (NIOSH) has published Current Intelligence Bulletin 70: Health Effects of Occupational Exposure to Silver Nanomaterials. According to the Current Intelligence Bulletin (CIB), NIOSH assessed potential health risk from exposure to silver nanomaterials by evaluating more than 100 studies of silver nanomaterials in animals or cells. The CIB states that recent studies in animals have demonstrated that biologic activity and potential...
The European Chemicals Agency (ECHA) is in the process of updating its guidance on the information requirements and chemical safety assessment (IR&CSA) for nanoforms under the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation. ECHA has developed three appendices concerning information requirements (appendices to IR&CSA Guidance Chapters R.7a, R.7b, and R.7c) to provide advice to registrants for use when preparing REACH registration dossiers that...

EFSA Panel Concludes That Titanium Dioxide Cannot Be Considered Safe as a Food Additive
On May 6, 2021, the European Food Safety Association (EFSA) announced that E171 is no longer considered safe when used as a food additive. The European Commission (EC) asked EFSA to update its safety assessment of the food additive titanium dioxide (E171). EFSA states: “Taking into account all available scientific studies and data, the Panel [on Food Additives and Flavorings] concluded that titanium dioxide can no longer be considered safe as a food additive. ...

EC Review of Its Recommendation on the Definition of Nanomaterial Includes Targeted Stakeholder Consultation
In 2011, the European Commission (EC) adopted a Recommendation on the definition of a nanomaterial. The Recommendation invites member states, European Union (EU) agencies, and economic operators to use the definition “in the adoption and implementation of legislation and policy and research programmes concerning products of nanotechnologies.” The EC is now reviewing its Recommendation. It has launched a targeted stakeholder consultation to update, test, and...
