PFAS (and, to a lesser extent, plasticizers) circulate from the blood to the gut ~5 times per day through enterohepatic circulation (https://en.wikipedia.org/wiki/Enterohepatic_circulation https://en.wikipedia.org/wiki/Enterohepatic_circulation). This is why cholestyramine was shown to be effective at reducing serum PFAS by up to 60% in a Swedish trial.
Blood donations are also somewhat effective, saunas less so. Also, to be clear, PFAS are very different from microplastics. PFAS are the Teflon chemical.
- amluto 5mo ago> the Teflon chemical Teflon is PTFE, which is fully fluorinated but is also very much a plastic: it’s a highly unreactive solid at reasonable temperatures (which sadly do not include temperatures commonly encountered on stoves). By “the Teflon chemical” are you perhaps referring to the various nasty liquid, water-soluble surfactants commonly used in factories that make or process PTFE? Those include PFOA, PFOS, and the newer and not obviously any safer “GenX” compounds.
- BenjiWiebe 5mo agoYes, they are referring to PFOA/PFOS; they're talking about PFAS which is the broad class of chemical compounds that includes PFOA/PFAS. And PFAS are not plastics.

I wonder if there's a safe way to equip people to just do simple bloodletting if they have high exposure to PFAS. I mean obviously it's better to donate, even in that case, given the steady state of most blood banks. But it's still a bit of a pain in the ass.
