The plastics themselves are only part of the story - they are relatively inert. However chemicals used to plasticize them and prevent fire are not, and some of them are already banned, but we have insufficient days on the replacements used. (Phenolics such as Bisphenol A - have hormonal effects causing direct cancer risk. And other effects too.)

I think it depends on the plastic. "Plastic" just refers to a mechanical property that a lot of different polymers have.

Also, note that while bisphemol A is largely banned from certain food-contact plastics, it has been replaced with other "plasticising" chemicals which are largely "the same" such as bisphemol E, F, S, or AF For the interested https://en.m.wikipedia.org/wiki/Bisphenol https://en.m.wikipedia.org/wiki/Bisphenol Also note n2, variations of vinyl or pvc plastic makes strong use of bisphemols for flexibility, pvc is being used to replace ageing copper or lead piping across the world, it is also largely unexplored the degree to which there is legislation regarding the sourcing and chemical composition of said water pipes over most of the world (as in, if there is a new international hotel building being built in, let's say brazil, what type of water pipe will the construction company use? You honestly think they would use copper everywhere and pay a 5x premium on it, or just use some random pvc pipe embedded on the walls? And then, if it proves to be that the pvc had bisphemol X on it, how would you even fix it? Rip it all up? We are talking of literal concrete bricks. Or just hide it from the public? )

  > pvc is being used to replace ageing copper or lead piping across the world PVC for water pipes seems to be a relatively US-only thing as far as I can tell. I don't think it's legal in the EU, for example; plastic piping here is PE-HD.
