Potentially ‘toxic’ face masks
“Health Canada has conducted a preliminary scientific assessment and has identified a potential for early lung toxicity in rats from inhaled graphene,” the substance coating the masks, said agency spokesman André Gagnon.
The health warning last week referred to a single model of mask, referred to as #SNN200642, imported by one supplier, Metallifer.
But a second mask is also under review because it uses the same material, called nanoform graphene, as a coating, Gagnon said.
“Health Canada is currently reviewing data from two manufacturers of graphene-coated face masks to determine the safety and effectiveness of their devices, and will take appropriate action as necessary,” he said.
In a statement, Metallifer said that it has stopped selling another kind of mask as well, known by the serial number #SMDP20605.
