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.
Health Canada said it conducted a preliminary scientific assessment after becoming aware that masks containing graphene were being sold with COVID-19 health claims and used by adults and children in schools and daycares. Health Canada also believes they may have been distributed for use in health care settings.
