The amount of microplastics in the human brain appears to be increasing over time: Concentrations rose by roughly 50 percent between 2016 and 2024, according to a new study

Nature, found that brain samples collected in 2024 contained significantly more microplastics than those taken eight years earlier. Researchers say the amount of plastic in the brain has increased by about 50% -- the equivalent of an entire plastic spoon in weight.

Human brains contain higher concentrations of microplastics than other organs, according to a new study, and the amount appears to be increasing over time.
