I don't think you should be downvoted, as it's a valid observation.
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.

- Reelin 8y agoThe wording of the grandparent comment was sloppy. You might try DOI 10.1039/C8NR09321K (https://pubs.rsc.org/en/content/articlelanding/2019/nr/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.
