Firstly graphene is a simple carbon chain, basically non toxic, it could cause distress if loose filaments were inhaled, absolutely, but know that graphite, which is pencil lead, if rubbed aggressively into thin layers on paper, creates graphene, in fact the first graphene manufacturing technique relied on dissolving graffiti in a mostly water solution(I think it had alcohol or hydrogen peroxide in it too) painting it on the back of a CD, turning a whole disk burner upside down and letting the laser from the encoder hit the solution and dry it progressively and very slowly into a single sheet that would not stick to the CD. Graphene is a wonder material and to my knowledge is on the short list of materials that might be used in future nanotech. None of that is in the NN article because this article is mostly just relaying info from a CBC article and reaffirming the readers views on masks, it is clickbait but further it is manipulative click bait that intentionally misquotes it's source. CBC article qoute: >>Some daycare educators had been suspicious of these grey and blue masks for a while because they felt like they were swallowing cat hair while wearing them, Radio-Canada has learned. Natural news misqoute to manipulate the reader emotionally: >>For a while now, some daycare educators had expressed suspicion about the masks, which were causing children to feel as though they were swallowing cat hair while wearing them. We now know that instead of cat hair, children were inhaling the equivalent of asbestos all day long. I'm sure there is some other bullshit involved I don't want to waste more of my time on that fucking joke of a publication which relies on rewriting national news media to generate clicks in a salacious and unscrupulous fashion.
