Coronavirus: Health Canada issues advisory for face masks containing graphene | CTV News

TORONTO — Health Canada has issued an advisory and asked distributors to recall masks sold with graphene or biographene in them over potential inhalation risks.

Graphene is comprised of a single layer of carbon atoms and is considered a nanomaterial, meaning it is made of tiny particles, and is reported to have “antiviral and antibacterial properties,” the advisory says.

The products affected are listed as “face masks labelled as containing graphene or biomass graphene,” the advisory states. Health Canada recommends that Canadians not use masks with the substance and to consult their health-care provider if they have used graphene face masks and have health concerns – such as new or unexplained shortness of breath, discomfort or difficulty breathing.

The organization said that their preliminary assessment of available research found that inhaled graphene particles had some potential to cause “early lung toxicity” in rats and other animals, but that the potential for people to inhale graphene particles – and the related health risks – are not yet known, and may vary with based on mask design.
