Lucky bastard. I'm not only unable to donate, but I have to get blood derivatives injected. I'm Plastic Person, be sad for me.

What about those who sell their seeds regularly?

Medieval-style bloodletting...

.A friend used to donate blood when he had sex with a random girl, he said that if he contracted HIV, they would contact him.

Also wouldn't work.

Interesting that someone would downvote that.

Incubation periods and rampant illegality and unethical behavior resulting in anyone that deserves to live in the first place shooting themselves in the head out of shame.

Donating my microplastics to people in need.

Bad news: Todays needles are coated in PFAS to make punctions more painless.

[–] SuperIce@lemmy.world 19 points 1 day ago (2 children)

That's kinda misleading though. Large molecule PFAS are harmless to us (Teflon for example). It's the small molecule PFAS are dangerous and those aren't really used for any kind of non-stick surfaces.

[–] Revan343@lemmy.ca 8 points 1 day ago (1 children)

They're part of the waste of producing non-stick coatings. So you aren't exposed to them by the needle or your Teflon frying pan or the Teflon tape in your plumbing, you're exposed to them by the Teflon plant dumping their waste in the river, legally or otherwise

[–] ryannathans@aussie.zone 1 points 21 hours ago

Which kinda PFAS do they use for hydrophobic coatings

[–] Ziglin@lemmy.world 2 points 1 day ago

I've never really looked into this, do you have any good sources you recommend looking at?

[–] Catoblepas@piefed.blahaj.zone 33 points 2 days ago (2 children)

As someone who takes a weekly shot, ARE YOU FUCKING KIDDING ME 😭

Uuugh I don’t want to switch to daily gel or patches, it’s such a pain in the ass.

[–] mustbe3to20signs@feddit.org 27 points 2 days ago (1 children)

Unfortunately no. Afaik even regular exposition is (for now) considered relatively harmless, with medical professionals bearing the highest risk.

[–] Noodle07@lemmy.world 3 points 1 day ago

I thought the injection would be the one that is a pain in the ass πŸ€”

[–] ronigami@lemmy.world 9 points 1 day ago

whose fucking goddamn idea was that

[–] ThatGuy46475@lemmy.world 91 points 2 days ago (3 children)

I’m removing so much plastic, this will make me healthy sips coke from bottle

Does ejaculation remove micro plastics? Asking for a friend.

[–] djsaskdja@reddthat.com 48 points 2 days ago (3 children)

Wait, would this actually work?

[–] Jessica@discuss.tchncs.de 65 points 2 days ago* (last edited 2 days ago) (7 children)

Yea it really does. It's the only way we know to get rid of plastic in blood

Keeping in mind that you're getting rid of the plastic in your blood by getting rid of her blood

[–] Catoblepas@piefed.blahaj.zone 33 points 2 days ago (1 children)

Some recent study also found that mucilaginous fiber binds with PFAS the same way that it binds with cholesterol to keep the body from absorbing it. PFAS already in your system is believed to be reintroduced to your digestive system through bile excretion, some binds with the fiber and leaves your system, the rest is absorbed.

If you don’t eat a lot of food with mucilage, the main ingredient in Metamucil has mucilaginous fiber, as the name suggests.

The study author in the interview I read emphasized it wasn’t like β€˜take fiber for a few months and PFAS is all gone,’ she and her husband just incorporated a mucilage supplement into their diets because of how prevalent it is in the environment.

Got link any chance? Would help me in telling my friends and loved ones to take poop pills with me because of the plastic in bodies (I’ll take my poop polls with or without a link just because I like the cut of your jib)

[–] Catoblepas@piefed.blahaj.zone 17 points 2 days ago (1 children)

I don’t think this was the exact article I read, but here’s another discussing the research: https://www.uml.edu/news/stories/2025/pfas-detox.aspx

Does this also mean woman after their period have less plastic?

[–] Jessica@discuss.tchncs.de 13 points 1 day ago (1 children)

Yes. Also during pregnancy. A lot of it is diverted to the fetus

[–] Little8Lost@lemmy.world 3 points 1 day ago (1 children)

so babies have already a high amount of plastics pre-birth?

[–] Jessica@discuss.tchncs.de 6 points 1 day ago

Yep! It's also a great way for the mom to remove some lead from her system. It ends up in the babies' teeth

Only if your exposure in the future is less than in the past. Otherwise it will just go back up again. And considering plastic use is going up, you would have to use air filters and avoid micro plastics as much as possible.

[–] WhyJiffie@sh.itjust.works 5 points 1 day ago

so it works, because in any case there will be less than otherwise would be

[–] vodka@feddit.org 15 points 2 days ago

I does! It also reduced heavy metal levels.

Thankfully the bad type that shouldn't be your blood, and not the cool type that should be playing on your speakers.

I'm doing the same, but for PFAS

[–] Hylactor@sopuli.xyz 26 points 2 days ago (5 children)

If human blood has plastics at a rate of ~ 1.6 Β΅g/mL and a typical volume of blood donated during a whole blood donation is approximately 470-500 mL you're looking at a reduction in plastics of a cool .0005 grams per donation. That's 1/40th of a grain of rice!

[–] Tar_alcaran@sh.itjust.works 36 points 2 days ago (1 children)

Don't think of it like that, think of it as 10% of your total blood plastic!

I wonder if doing plasma instead of whole blood is better or worse. Does microplastic stay behind or go back in?

[–] reallykindasorta@slrpnk.net 24 points 2 days ago (3 children)

Damn apparently giving plasma might be better according to this small study of aussie firefighters

Thats why i donate 3 times a day

[–] InnerScientist@lemmy.world 18 points 2 days ago (4 children)

Too inefficient, I'm just going to pump it all out and start again with fresh blood.

So you gotta do a full flush when you donate. Got it.

why would you use absolute values for something measured in such small quantities? show us the percentage that comes out. or the fraction of the grain of rice associated with kidney / liver damage
