Comment on Scientists discover promising new way to filter microplastics out of human body: 'The dose makes the poison'

  Oh, and I suppose you’ve figured out a more modern way to balance the humors‽

  Describing donating a pint of blood every several weeks as “regular bloodletting” is really something. I mean I guess in a literal sense that is what is happening, but they literally will not take your blood if it is not safe to do so, including donating too recently.

    I know pfas levels are immediately lower after the donation. I’m not under the impression that pfas levels stay low for very long i.e. long enough to safely donate blood again.

    Also, it’s kind of messed up that we’re donating contaminated blood. Is that good for the people that use our blood? Who knows!

      I think it’s definitely worth doing some serious math first before publicly writing it off. Even if its a marginal benefit, as long as its just a tiny bit greater than the marginal benefit you get from intentionally avoiding exposures as much as reasonably possible, then over time the PFAS levels will come down slowly but steadily

      Secondly, no its not okay to give people contaminated blood. But the blood is contaminated with something basically everyone is contaminated with already, and the person who needs transfusion will likely die without it, so it is kind of moot.

      But after only a few more moments of thought, if we were really concerned about it, we could just perform the dialysis on all the donated blood and plasma after it has been taken where we have economies of scale and nobody needs to be hooked up to a machine for it

        Looks like patients that receive hemodialysis treatment have lower pfas levels, so that actually might be viable!
