It doesn't seem to be the PTFE themselves, it's the molecules released when it eventually degrades due to fire, time or mechanical force; particularly PFOAs, which were at one point so widely used you can now find them everywhere. As well, they are still used to manufacture non-stick pans, just at an earlier step in the process so they are still present, but at 'safe' levels; however, if a non-stick pan is overheated, the coating almost instantly breaks down and releases unsafe levels of PFOA after that event.
Purchasing non-stick cookware is supporting companies that create, ship, and use PFOA which further degrades the environment and contaminates water.

My research is currently with pfoa and its ability to interfere with ttr proteins ability to transport t4 and t3. If you need a source just google pfoa calux.
Thanks for your work. (☞ ͡° ͜ʖ ͡°)☞
