PFAS is a chemical category containing fluorinated polymers. Think old timey ScotchGuard. It can be nasty stuff in the body. But I don't think there has been good connection between it actually causing health issues.
Not sure how insecticide is involved. As usual there are other ways of solving problems than banning substances. There are test procedures you can use to identify issues. There are processing guidelines you could use. But state lovers like to ban things that sound scary.
