It's not what microplasitcs are! Does anyone knows what micro is at this point?
If these aren't microplastics, what are?
"Micro" just means "small" in this case and doesn't mean "microscopic" or have anything to do with "micrometer".
The definition of "microplastic" according to NOAA: "Microplastics are small plastic pieces less than five millimeters long".
1x10^-6 m.
-Wikipedia
Millibeads
Centibeads🐛
To add to this, the definition of microplastic is less than 5mm. So yes, 1mm microbeads are microplastics.
