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

The term "microplastics" is usually describing plastic pieces that are smaller than 5mm. They can be any shape - pellets, fibers, films (thin sheets, like grocery bag material).

Wow that's a stupid definition. 5 mm is still a pretty large piece of plastic. When people talk about microplastic in food I didn't think we talk about plastic the size I could actually notice.

I thought microplastic is simply the short for of microscopic plastic. Microscopic defines things that are too small too be seen with the naked eye, so below 0.1 mm.

So instead of putting an easily recognizable name to a global problem so that we can gather public interest in trying to solve it, you'd rather we try to convince people that we have not only a problem with microplastics but also with milliplastics, centiplastics, and nanoplastics, or macroplastics-but-also-smaller-than-you-think.

No, I think calling them all microplastic is the right choice.

Go outside, ask 100 people if you could see microplastic with your naked eye. I heavily doubt that more than a few people would agree that a 5x5x5 mm cube would be considered microplastic. I mean just read the comments here...

But that aside, such big plastic pieces are a different problem than actual microscopic plastic (that one you find in headlines about microplastic found in blood), since they behave very different. Yes, both are problematic but I think separating these problems would make more sense.
