Health Canada conducted a preliminary risk assessment which revealed a potential for early lung damage associated with inhalation of microscopic graphene particles. Graphene is a strong, very thin material that is used in fabrication, but it can be harmful to lungs when inhaled and can cause long-term health problems.
Patrick Baillargeon, who is charge of purchasing Quebec’s laboratory supplies, warns in a letter that Health Canada has not received any data to support the safety and efficacy of face masks containing graphene particles and therefore considers the risks associated with these medical devices unacceptable.
