I guess this shouldn't surprise anyone. Yay, our brains may be one of the most polluted of the organs.

In one of the latest studies to emerge – a pre-print paper still undergoing peer review that is posted online by the National Institutes of Health – researchers found a particularly concerning accumulation of microplastics in brain samples.
An examination of the livers, kidneys and brains of autopsied bodies found that all contained microplastics, but the 91 brain samples contained on average about 10 to 20 times more than the other organs. The results came as a shock, according to the study’s lead author Matthew Campen, a toxicologist and professor of pharmaceutical sciences at the University of New Mexico.
The researchers found that 24 of the brain samples, which were collected in early 2024, measured on average about 0.5% plastic by weight.
“It’s pretty alarming,” Campen said. “There’s much more plastic in our brains than I ever would have imagined or been comfortable with.”
The study describes the brain as “one of the most plastic-polluted tissues yet sampled”.
