What's the cost of even identifying all the ways these chemicals are getting out, or what all these chemicals are?
I heard recently that but and seed butters often have elevated amounts of this crap... One hypothesis floated was that machinery used in the processing of this food is being coated in the stuff.
- nonrandomstring 3y agoWe know where a lot of it came from. Emphasis because it's an historical problem: Military and civil air fire-fighting foam. About a million tons of perfluoroalkyl was put into the environment between 1970 and 2000. It's very mobile, so it quickly got into groundwater and rivers. By comparison the leach from Teflon pans is probably a small percentage.
- NewJazz 3y agoOh I definitely agree that Teflon pans are low on the list of pollution sources. But firefighting foam doesn't explain wtf happened (is happening?) to Cape Fear.
- hunter2_ 3y agoFood packaging is full of this stuff. Think about how a greasy sandwich or stick of butter is wrapped in a magic piece of paper that somehow doesn't get completely saturated with grease/sauce... that's PFAS.
- mjrpes 3y agoThey make PFAS free wax paper.
- choilive 3y agoTo the machinery example - the dies used to make pasta are teflon coated because that means you can push the dough through the dies faster. Likewise dental floss often has PFAS coatings to make it easier to slide between your teeth. This stuff is literally everywhere and cannot be avoided.
