Canada’s health department advises against using face masks containing graphene until it assesses their safety – warning there is the potential for users to inhale particles “which may pose health risks”.
Face masks containing graphene or biomass graphene are being removed from the market as a “precautionary approach”.
“Health Canada’s preliminary assessment of available research identified that inhaled graphene particles had some potential to cause early lung toxicity in animals,” the department said.
“The potential for people to inhale graphene particles from face masks and the related health risks are not yet known and may vary based on mask design.
“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.”
