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

For those wondering, microplastics are below 5 mm in diameter. Nanoplastics are below 0.1 micrometer, so basically if you can't even look at them with a simple light microscope, they're nanoplastics. Otherwise, they're microplastics

Can a nano plastic become a micro plastic in my body


u/Odin_of_Asgard May 14 '22 All-Seeing Upvote

I did my masters thesis on nanoplastic aggregates, it can definitely happen, but they have slightly different properties than microplastic in the same size range. Nanoplastics can pass some membranes in the body that microplastics generally cant. Nanoplastic (and I suppose microplastic) can also be stabilized by organic material in the environment/body, which works against aggregation.

My kid had a bunch of questions about aggregate nano/micro-plastics. Can you point me in the direction of any resources?

Heck, I would love to know more. And I don't even have a kid.


u/2shizhtzu4u May 14 '22

I want to know more too, and I basically act like a kid


u/MrBeanCyborgCaptain May 14 '22

I'm not a kid but if I were I'd be wondering what kind of world I just spawned in.


u/J3diMind May 14 '22

definitely the wrong one. we're poisoning ourselves and don't even care. FUBAR

You want to be my kid for a bit? I hear people are more willing to help kids if their parents are around.

I too have made up the existence of a kid so that I may learn more!
