Currently, a systematic comparison of the neurotoxic effects of different particle types, shapes, sizes at different exposure concentrations and durations is lacking, but urgently needed to further elucidate the neurotoxic hazard and risk of exposure to micro- and nanoplastics.


IOW, there's no evidence of a problem, but there might be a problem.

I get it - society and technology are changing rapidly and we really don't know all the implications. But there are big problems now that we already know that are causing huge health and safety issues in the US - the pandemic; lead; maternal healthcare and abortion restrictions; climate change; etc.

Yes, research the new stuff, but don't get distracted.
