Scientists have made a disturbing discovery: human brains contain microplastics, and at higher concentrations than other organs. Worse, brain levels have jumped 50% in just eight years.

Even more concerning was the finding that the amount of plastic in the brain was increasing over time. Brain tissue samples from 2024 had significantly higher levels of microplastics than samples from 2016, representing an approximate 50% increase in just eight years. The predominant type of plastic found in the brain was polyethylene, a common plastic used in packaging, bottles, and cups.
