(Eagle News) — Health Canada has ordered a recall of face masks that contain graphene particles.
Graphene is a nanomaterial, a material made of tiny particles. These particles are thought to have anti-viral or anti-bacterial properties.
“Until the Department completes a thorough scientific assessment and has established the safety and effectiveness of graphene-containing face masks, it is taking the precautionary approach of removing them from the market while continuing to gather and assess information,” Health Canada said in an alert.
The agency says the masks have been sold with Covid-19 claims. It says they are being used by children and adults in schools and daycares. They are also believed to have been distributed in health care settings.
The agency says its preliminary assessment of available research indicated if inhaled, grapheme particles can cause lung toxicity. This research was done on animals.
“The health risk to people of any age is not clear,” Health Canada said. “Variables, such as the amount and duration of exposure, and the type and characteristics of the graphene material used, all affect the potential to inhale particles and the associated health risks.”
Health Canada has asked manufacturers of these masks to provide it with data on the masks so an assessment of potential health risks can be one.
The agency also asks people who have used the masks to contact the agency if they have any new or unexplained breathing difficulties.
People who have bought the masks should stop using them.
