Canada has prohibited using face masks containing graphene because of the chance to dangers from inhalation of particles.

Health Canada introduced on Friday that it has “directed all known distributors, importers and manufacturers to stop selling and to recall the affected products”.

The division is presently within the midst of a scientific evaluation of the graphene and biomass graphene masks even because it initiated the “the precautionary approach of withdrawing them from the market while continuing to gather and assess information”.

Graphene is a novel nanomaterial, comprising minute particles, which has been touted as having “anti-viral and anti-bacterial properties”.

According to a report in September final yr, researchers on the City University of Hong Kong claimed that such masks might assist in countering coronaviruses.

However, Health Canada mentioned that its “preliminary assessment of available research identified that inhaled graphene particles had some potential to cause early lung toxicity in animals”.

That evaluation got here after the division was made conscious that “masks containing graphene have been sold with Covid-19 claims and used by adults and children in schools and daycares” and “may also have been distributed for use in healthcare settings”.

While the recall was introduced on Friday, such masks, manufactured utilizing nanotechnology, stay broadly accessible in Canada, and in India.

While the impact of inhalation of the microscopic particles in people continues to be being studied, Health Canada mentioned that it has “requested data from mask manufacturers to assess the potential health risks related to their masks that contain grapheme”.

Health Canada added that it has written to provinces and territories advising them to “stop distribution and use of masks containing graphene” whereas the division “will continue to take appropriate action to stop the import and sale of graphene face masks.”
