        The PFAS/PFOA controversy, is mostly about banning these commodity products so that the proprietary, non-commodity alternatives by western companies can become the only high temperature dry lubricant on sale.

        Maybe in another 60 years we’ll have the same controversy about them !

          No it isnt, its about the production precursors being literal poison for anything they get into with no chance of breaking down. Its a unusually harmful and persistive compound.

              Hey friend you know the chemicals they make those things from are like WILDLY carconogenic right? And that PFAs and their cousins last forever and don’t break down in the environment?

              These chemicals are being banned because humans got too good at making super stable fuck-you-big molecules that just so happen to be wildly incompatible with anything that has DNA. These chemicals are literally everywhere with water treatment facilities having acceptable limits 2ppb or less. Yea, B, Billon. The thing with that amount though, is even THAT isn’t safe, its just regulable. Here’s an oversimplified video on the subject by Veritasium, the clickbait headline is just that. I believe this is also on nebula if you’d prefer to avoid youtube.

              Dude it’s literally poison what do you want??? It also leeches into the environment extremely easily.

          Did you at some point read about how some of them, such as the ones used in frying pans, are unlikely to cause problems in the human body, and then completely stopped looking into it further?

          It’s a massive group of compounds, some of which currently look to be quite safe, but a significant number of which also have fully verified dangers (especially some compounds required for production).

            Yes, I read about it and the teflon on frying pan is explicitely NOT the problem. I understand that pointing to frying pans and saying “PTFE !!” is the attention grabbing thing to do. But there is no danger here.

            The problem is the manufacturing plants leaking PFOA/PFAS into their surrounding environment !

                That’s been well known for over 50 years, why do you think now, all of a sudden, this is becoming an issue now ? This is because there are new coatings, silicon based PTFE-free coatings and PTFE-based metamaterial that combine titanium, ceramic and/or PCD.

                As the manufacturer invest in this new technology, they either restrict PTFE commodity manufacturers out of their market or merely stop funding lobbying that protects the PTFE.

                This is not a conspiracy theory, simple emergent interests that do not require a coordination.

                  Abestos was used for millenias, and was known the miners a thousands years ago would succumb to a mysterious illness after working years in the mines… and it was just banned in the US in checks notes. Last year. Must’ve been big fiberglass behind it!

                  Cool.

                  But the reason you’re being downvoted, is that instead of commenting this, you made a comment that sounded like you were dismissing the dangers of PFAS, and dismissing it as the modern-day equivalent to lead, asbestos, and the like.

                  Which is what it is, and you clearly agree that it is.

                    The difference with leaded gasoline and asbestos, is that everyone everywhere was being exposed to those.

                    And the current trajectory regarding PFAS is, a complete ban https://www.wcl.org.uk/transitioning-to-a-pfas-free-economy.asp

                    But they’re not a problem everywhere, they’re a problem of containment at the manufacturer.

                    This is what sloppy statements like plastics and teflon are tantamount to the widespread lead and mercury poisoning. That’s just not the case but acting like it is, is exactly how industry initiate regulatory capture.

                    I see it the same as the big tech giants pushing hard FOR regulation, because ultimately the rules, written with their impetus will become their motes and we will all pay for it.

      Except plastic doesn’t really seem to do anything. It just “is there”. Unless you swallow enough of it to clog something, it doesn’t seem to do anything.

      We’ve seens lots of “it might interefere with hormones”, but that part is always to be confirmed in the next research grant request and then we never hear about it again.

        Plastics are a broad category. But specific plasticizers, like BPA, have been demonstrated to cause specific endocrine issues, up to and including a causal link to certain cancers, miscarriages, and other reproductive/immune issues. And it’s not just correlations being found, as the research is showing the mechanism of action by actually inducing the effects in vitro.

        And so when a particular plasticizer has been shown to be harmful, the research goes into other chemically similar plasticizers to see whether they have biological effects, as well. BPS is another plasticizer that is being studied, as it is chemically similar to BPA.

        So we haven’t shown that all microplastics are bad. I’m skeptical that these effects would extend to all plastics. But some common compounds that are present in many plastics are a cause for concern, and the difficulty in treating water or waste for microplastics in general means that some of those harmful compounds are present in lots of places where we’d rather not.

        We moved from leaded gasoline to unleaded gasoline based on the specific dangers attributable to lead itself. We can do the same for the specific compounds in our plastics shown to be harmful. Maybe the end result is that we have a lot of safer plastics remaining. But your comment seems to suggest that we not even try.

          I’m more concerned about useless and damaging, performative actions against plastic.

          Of course what we need is plastic monomers that are neither carcinogenic nor hormone disrupters. We should stop dumping the stuff into the river. Poisonned blastic with bromine should be labelled in a was that makes it easy to identity. We should breed yeast that can east plastic and keep them in giesters.
