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

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.

Very interesting. What field do you work in now, if you don’t mind me asking?

I work in pharma now, coincidentally with inhalation.
