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 38 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 27 points 2 days ago (1 children)

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

[–] cannon_annon88@lemmy.today 12 points 2 days ago (2 children)

Ooh maybe I should donate again. Get some extra cash, get rid of micro plastics. Win win win.

I'd argue it's better to call it "sell" when you get paid to do so.

Just like I am not donating money to Lidl to buy sour gummy worms.

Go drinking after for an extra efficient sesh

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

[–] FireRetardant@lemmy.world 22 points 2 days ago (1 children)

Thats why i donate 3 times a day

[–] InnerScientist@lemmy.world 19 points 2 days ago (1 children)

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

The trick is to find a blood boy like Peter Thiel

[–] Deceptichum@quokk.au 7 points 1 day ago (1 children)

Why would I want Peter Thiel as my blood boy?

[–] Quetzalcutlass@lemmy.world 4 points 1 day ago (1 children)

Nowhere was it said that you had to give any blood back.

Plus you get free experimental life extension drugs and maybe after it’s done your retinas directly interface with Palantir

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
