1. Any substance that has most atoms covered by Fluoride are 'PFAS'.
2. C8 is strictly speaking PFOA (by-definition).
3. C6, and all other acids that has similar chemical properties to C8, can all be generically classified as PFOA-like materials. But for ease of communication people also call them PFOAs or just short for PFOA.
4. PFOAs are crucial for manufacturing Teflon.
5. The problem is manufacturers just dump waste water from PFAS production plants (containing PFOA) without post-processing into natural water bodies and let these toxic substances participate in the food chain and eventually land in our own bodies.
