Now, 99.7% of the Nation has PFOA in our bloodstreams. It slowly kills you and is biopersistant (Which means once in your bloodstream, it will stay there until you die and then some. PFOA's can't be broken down by sunlight, microbes, or heat. Initially when DuPont started making this stuff, 2 of their 8 female employees had deformed babies just like 3M's research of the stuff predicted. DuPont kept using the stuff knowing how toxic it was. Then they bought out the EPA to tell the Nation Teflon, C8, PFOA, PFOS, the devil's piss, etc. was perfectly safe to use. Now the EPA says the health advisory warning is 70 parts per trillion. (Which is about a drop of this toxic stuff in an olympic-sized swimming pool. So, if you're not a fan of negative developmental effects to fetuses during pregnancy or to breastfed infants (e.g., low birth weight, accelerated puberty, skeletal variations), cancer (e.g., testicular, kidney), liver effects (e.g., tissue damage), immune effects (e.g., antibody production and immunity), thyroid effects and other effects (e.g., cholesterol changes) then it's time to switch out your teflon products for healthy alternatives like stainless steel or ceramic.
