Aren't nanoplastics a larger concern?

All microplastics out in the open will degrade to nanoplastics at some point, and those find it much easier to infiltrate the human body. They penetrate the blood-brain barrier.

This leads me to believe that it's literally impossible to avoid. The air/water supply must be getting more poluted by the minute with these things

I wonder if plastics, being non-polar, might accumulate in organs which are a bit on the "oily" side - the liver, adipose tissue, and the brain.
