Microplastic particles are increasing in the human brain, while new research shows that the problem is getting worse over time.
The new study, published in the journal Nature, found that brain samples collected in 2024 contained significantly more microplastics than samples taken eight years earlier.
The researchers say the amount of plastic in the brain has increased by about 50 percent, which is equivalent in weight to a teaspoon of plastic.
Matthew Kempen, a professor of pharmaceutical sciences at the University of New Mexico and co-lead author, said that microplastics were found in the brain by about 50 percent compared to brain samples from 2016.
He added that this would mean that today our brains are 99.5 percent made up of brain material and the rest is plastic.
