Anses also recommends graphene-free masks
In a press release and a report published today, Anses (the French Agency for Food, Environmental and Occupational Health & Safety) confirmed the lack of data on the nature of graphene used in some masks, on its usefulness and on its safety. These uncertainties, combined with the possible environmental end of life consequences of the masks, reinforce the calls for the precautionary principle launched in early 2021 in Canada and then in Europe. Anses concludes that “Since graphene-free masks that comply with the standards and have demonstrated their particulate filtration efficiency are also available on the market, (…) it is not relevant that masks containing graphene be placed on the market, either for the general public or for professionals.
In another opinion published the same day, Anses concluded that there were no concerns regarding the wearing of surgical masks made available to the public and under conditions respecting the authorities’ recommendations. However, Belgian authorities have found nanoparticles of titanium dioxide and silver in consumer masks. In France, the authorities have not conducted tests to look for these substances (nano or not).

Upcoming Nano Agenda



- Workshop on risk assessment of nanomaterials and materials containing small/nanoparticles in the food and feed chain
- Organizer: EFSA
- This workshop will present the proposed strategy for updating the EFSA Nano Guidance documents, aiming to merge them into a single guidance on risk assessment for nanomaterials and small/nanoparticles in the food and feed chain.
The event will provide an open platform for discussing key issues, approaches to addressing them, and ensuring the guidance reflects the latest scientific knowledge. Stakeholders will be encouraged to share experiences and engage with regulators, helping shape the updated guidance. - Website: www.efsa.europa.eu/en/events/workshop-risk-assessment-nanomaterials-and-materials-containing-smallnanoparticles-food-and
- This course is designed for engineers or senior technicians working in the field of micro and nanotechnologies in public or industrial laboratories, who need to solve problems related to controlling the properties of materials at the nanometric scale during their development and/or integration into devices.
