Microplastics Have Reached the Human Brain, and the Concentration Is Worse Than Expected
Ben Sullivan
The numbers came back wrong. Researchers at the University of New Mexico had been methodically working through preserved brain tissue, running the usual analyses on samples drawn from a cohort of donors spanning 2016 to 2024. What they found was not a trace signal or a statistical whisper. The human brain, it turned out, carries microplastic concentrations seven to thirty times higher than matched samples of liver or kidney from the same donors. And over those eight years, the cumulative burden.
