This source mentiones if something is smaller than some arbitraty limit there's no sense counting it because it's probably just sand not something that came from the glass ampule. Therefore small sand is common enough that it would skew their result to be something nonsensical.
You need to read between the lines because apparently nobody researched how much sand average person has in their bodies because it's not interesting.
Why don't you show me research supporing your claim that body doesn't contain sand particles in amounts at least comparable to amounts of microplastics detected?
