> it’s kind of irrelevant to compare different substances toxicity based on quantity alone

While this is true, it applies with even more force to the comparison with botulinum toxin than to the comparison with aspirin. Nanoplastics are less active than aspirin, not more (there's a reason why nobody takes nanoplastics to cure headaches), so if anything one would expect to require more nanoplastics than aspirin to have a significant effect--which means even much more more, so to speak, than botulinum toxin.
