Couldn't they do some dialysis type thing with our blood somehow? Idk shit about science lol

[–] L0rdMathias@sh.itjust.works 77 points 1 day ago (4 children)

Yes, in theory. It's extremely dangerous and absurdly expensive. It also would only address the microplastics currently in the bloodstream - the ones already embedded into organ tissues wouldn't be reliably filtered out this way.

When it comes to PFAS contamination, people have been having decent results by simply donating blood often. Getting it out of the system via blood does help to reduce overall levels in your body.

I love how we've come back around to bloodletting

I am so disappointed in my kidneys for not getting rid of this stuff for me.

[–] Rivalarrival@lemmy.today 29 points 1 day ago (5 children)

Donating plasma works even better. They extract a larger volume of fluids per session, twice a week instead of once every 8 weeks.

Don't worry about the recipient: If you are donating plasma regularly, your PFAS levels will be well below average.

wait are you guys serious? I know about microplastics and pfas in us but is it a fact donating helps to get rid of some?

[–] Rivalarrival@lemmy.today 4 points 21 hours ago* (last edited 20 hours ago)

For PFAS, yes, definitely. They've done studies on this, some are linked elsewhere in the thread. PFAS in the bloodstream is removed through either whole blood or plasma donation.

For microplastics, I can't say with absolute certainty, as I don't know the concentration of microplastics in the blood, or if replacement blood/plasma contains microplastics. But, the mechanism is the same: extract polluted fluids; allow body to replace with non-polluted fluids. Concentration of pollution falls.

A woman having a child is the biggest reduction. Make of that what you will. I sure hope the placenta, and not the baby, is getting the remainder. But I am guessing both.

Here's a source for anyone interested. I just tested my well water where I'm at and it's 10x over the legal EPA limit :( . Might be testing my blood next and heading to the plasma donation center!

[–] Rednax@lemmy.world 5 points 1 day ago

TIL. Thank you!

[–] Rednax@lemmy.world 16 points 1 day ago (1 children)

Huh, I thought that they only filtered your blood when donating plasma, hence the PFAS could simply be returned to you. But I have to admit that I'm far from an expert on this matter.

Either way, we kinda have returned to bloodletting being a reasonable medical approach.

[–] Rivalarrival@lemmy.today 17 points 1 day ago

They centrifuge your blood and return the RBCs, but the PFAS hangs out in the plasma. Mostly. If there was much in the red blood cells, the liver would be removing it and you'd be pooping it out.

[–] Zagorath@aussie.zone 8 points 1 day ago (2 children)

Wait, you can donate plasma two times in one week where you are? That feels kinda insane.

In Australia it's 12 weeks for whole blood and 2 weeks for plasma. Or 4 weeks for switching from whole blood to plasma.

[–] ayyy@sh.itjust.works 7 points 1 day ago (1 children)

It’s so much worse than you realize. All blood and plasma must be obtained by “donation” for obvious ethical reasons, but American prisoners get incentives for participation/punishment for non-participation. Private American medical companies make billions of dollars in profit every year selling blood on the international market, but the prisoners don’t see a dime of it. The sellers are so unscrupulous that they have been caught knowingly selling tainted prisoner blood, and continuing to do so after being caught.

[–] Rivalarrival@lemmy.today 5 points 1 day ago* (last edited 22 hours ago) (1 children)

The events you're talking about occurred from the 1970's to 1983. They haven't done prison blood drives or accepted plasma from prisoners in over 40 years.

If you've spent more than 72 hours incarcerated, you are ineligible to donate blood products for 12 months.

[–] Machinist@lemmy.world 1 points 21 hours ago

Not OP, but I was unaware of that. That must have caused most all the AIDS that was caught through transfusions.

[–] Rivalarrival@lemmy.today 7 points 1 day ago

Yep! US allows plasma donation up to two times per week, with at least 48 hours between donations.

Can't donate plasma or blood for 8 weeks after donating whole blood, or 16 weeks after donating packed RBCs.

Packed RBCs are basically the reverse of plasma donation. Instead of returning the RBCs and keeping the plasma, they take two units of RBCs and return the plasma.

[–] Rivalarrival@lemmy.today 13 points 1 day ago (1 children)

It's called "plasmapheresis", and they'll pay you $40 twice a week to sit in a chair for an hour while they do it.

[–] L0rdMathias@sh.itjust.works 11 points 1 day ago (1 children)

They're so nice to do this out of the goodness of their hearts for any random person that asks for the procedure, at a financial loss, with no ulterior motive whatsoever.

[–] Rivalarrival@lemmy.today 10 points 1 day ago

I mean, if you really want to, you can go to the hospital and pay them to provide the exact same treatment.

[–] FerretyFever0@fedia.io 10 points 1 day ago

Well, that's great. Can't wait to have a kids toy in my brain.

[–] Deceptichum@quokk.au 9 points 1 day ago (1 children)

Extreme heat can destroy plastics, if I were to say self immolate would that be enough to remove the imbedded plastics?

[–] SpaceNoodle@lemmy.world 5 points 1 day ago (1 children)

Yes, but then you'd open a new hole in the ozone layer.

[–] crawancon@lemm.ee 3 points 1 day ago

yes but immolation of thy self could be a hoot

[–] abbadon420@lemm.ee 12 points 1 day ago

Unfortunately, it doesn't stay in the blood. Sometimes it wedges in nooks and crannies, where I accumulates and doesn't leave until a tumor pushes it out.

[–] Lumisal@lemmy.world 3 points 1 day ago* (last edited 1 day ago)

From what I've read yes.

Which is why all this years I had kidney failure I had spent going plastic free as possible, since I had a probably decent plastic free blood. Can't build up much if it gets filtered 3x a week.

The needles a gigantic btw.
