The Canadian Department of Health (Health Canada) has recently banned the marketing and free delivery in hospitals of masks containing graphene, which are being investigated by health authorities for suspected serious health consequences.
As reported in an official report from the health agency, the agency is advising people not to wear masks with graphene or biomass graphene. A preliminary assessment of developing research suggested that the particles cause early lung toxicity in animals and could do the same in humans.
Health Canada said it is working with mask manufacturers to assess their potential impact on people’s health, so it recommended their immediate suspension.
“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,” the agency said.
The agency asked Canadian citizens not to use the masks for the time being and report any adverse events on a Health Canada online reporting platform.
Adults have used graphene-containing masks in Canada, including children in schools and daycare centers have done so. The masks may also have been distributed for use in health care settings, the agency said.
