In this case they directly injected the nanoplastics + α-synuclein into the brains of one group and as a control injected only α-synuclein.

However, mice that have human α-synuclein have been around for decades, and nobody has (so far) noticed any effect of plastics on the development of Parkinsonism in these mice, neither are there any claims that Parkinsonism is more prevalent in people who have plastic implants of one kind or another.

Note that people ingest plastics all the time, e.g. through the breakdown of toothbrush bristles.

Plastics are found in human blood/lungs/breast milk/placenta etc, so the concern is much stronger than just accidental ingestion from a toothbrush.

Read about effects of xenoestrogens, which a bunch of these plastics apparentlt are, and cross check with some realities of today.

Yes, I appreciate the risk of plasticisers, and these should be addressed.

However, by the time an item made of plastic has become a "microplastic", these plasticisers have been leached out.

BPA is not a plasticizer.
