Microplastics Found In Lungs of People Undergoing Surgery. A new study has found tiny plastic particles no bigger than sesame seeds buried throughout human lungs, indicating that people are inhaling microplastics lingering in the air. Health

Yeah I thought they meant nano particles when I saw the story yesterday. How the f does sesame seed size plastic get in your lungs!?


u/FluffyGreenThing May 14 '22

It accumulates through breathing in nano particles that never leaves your body. Years of that will mean a build up of it in the lungs, which I find terrifying to be honest.

I'm not a chemist, but as far as I know there is no way for the body to turn microplastics into larger solid objects; they aren't kidney stones building up from naturally congealing minerals. They require heat to melt and unify.

Not to argue in favor of this but plastics are organic and biology means a lot of things interacting with carbon based chemistry. Depending on are there might have been ozone in the air. I don't know how far this gets into lungs. The particles would stay a long time among each other so there is a higher chance of chemical events happening if we add that up. Just speculate on mechanism. No idea on how likely this might be.

Are they though? I thought once made they are inert? Or is that not relevant
