Nanoplastics in the human brain and their change in abundance over time

Nature Medicine 2025 5 citations ? Citation count from OpenAlex, updated daily. May differ slightly from the publisher's own count.

Summary

Researchers identified nanoplastics in human brain tissue from cadavers and found concentrations were higher in the brain than in the liver or kidneys, with levels appearing to increase over time between 2016 and 2024, raising concern about the neurological implications of plastic particle accumulation in the human body.

Nanoplastics were identified in human brain samples from cadavers. Concentrations were higher in the brain than in the liver or kidneys, and appeared to increase over time between 2016 and 2024. Visualization of the plastics using a variety of approaches provided insights into the anatomical distribution and physical characteristics of nanoplastics.
