It's worth noting that all "forever chemicals" have major health concerns. PFAS, as a class, is the one most studied. They have been explicitly banned in many countries (e.g. France and Sweden) and even some US states (Maine, Minnesota, etc).

But it's a bit like how the DEA has to update their list of banned substances multiple times a month because people keep coming up with new designer drugs and "research chemicals" that aren't technically banned.

I think a broader umbrella term might be POPs (Persistent Organic Pollutants) though that might also be too broad to be useful. A lot of times it's their non-stick properties themselves that make them so toxic, especially to fish and smaller organisms.

PTFE is perfectly safe as long as you don’t get it too hot. So, not the best material for non-stick pans.

The thread tape on all non-compression screw-type plumbing fittings is made of PTFE, and so is Gore-Tex.

I’m well aware of the danger of PFAS, my local watershed is contaminated with it from a 3M plant.
