If it is, I assume it’s measured in thousandths of a gram or something, but are we all nevertheless a wee bit heavier than we ought to be?

I really had to run a fact check on this but it really does seem to be true.
Brains are 0.5% plastic by weight and with an average human brain mass of 1.3 kg, that means humans, on average, have 6.5 g of plastic in their brain
The actual paper https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11100893/
It’s still a preprint, and I didn’t see the exact figure but definitely concerning.
The exact data is Figure 1, chart A. It seems the mean is around 4,000-5,000 μg/g, which is indeed 0.4-0.5%
