Poly- and perfluoroalkyl substances (PFAs) repel both oil and water. So, as Anna Robuck wrote last fall:
"...PFASs are everywhere: fire-fighting foams, nonstick cookware like Teflon, stain-resistant carpet, water-resistant clothing, food packaging, compostable plates, some cosmetics, and other consumer products that repel oil, grease, or water."
They're ubiquitous, and because of that, they end up in our bodies. Now, the European Food Safety Authority says that humans can tolerate approximately...*pulls out adding machine*....99.9% of what they've been exposed to in the past.
In respone to this news, Robuck shared her thoughts:
"Ugh. Add this to the very-recent news that the US will refuse to set drinking water limits for these compounds.
My family lives near DuPont HQ, and some back of the envelope calculations suggest they (we) are drinking the weekly limit suggested in your link over the course of about three hours."
