A recent study revealed a high concentration of microplastics in human brain tissue, with some samples containing as much as a teaspoon of plastic, raising concerns about their potential impact on health. The study was published in Nature Medicine.
Researchers analyzed a total of 91 brain samples collected from deceased individuals, detecting plastic particles in all of them, with concentrations higher in brain samples than in the liver and kidneys. On average, seven grams of microplastic particles were found in the brains examined.
The study, led by Professor Matthew Campen and his team at the University of New Mexico, compared the plastic content in brain samples taken from cadavers who died in 2016 to those prepared in 2024. They found higher concentrations of microplastics in brain and liver samples from 2024,…
