I don't doubt that microplastics are not good for the environment and organisms that consume them, but can you provide a citation for the toxin concentration claim so I can learn more about it?

The wording of the grandparent comment was sloppy.
You might try DOI 10.1039/C8NR09321K (https://pubs.rsc.org/en/content/articlelanding/2019/nr/c8nr0...).
In summary, for whatever reason it seems that nanoparticles of some plastics readily penetrate and accumulate in biological tissues. There are also chemicals that will adsorb onto these nanoparticles. This can make a chemical at a given concentration more toxic to an organism, or even potentially make something toxic that was previously not.

Top 3 results here should do fine.

That was my point, to suggest that the size of the particles alone shouldn't pose a hazard, there must be more going on.
Nanoplastics concentrate toxic compounds within themselves, smuggling them past animals' defense system. This does not happen with rock. There has not been enough time for animals to evolve systems to remove nanoplastics from their bodies.
