Microplastics Found in Human Brain Tissue, New Study Reveals

Researchers discovered tiny plastic particles in the olfactory bulbs of cadavers, raising concerns about potential brain exposure.

The study, published in JAMA Network Open, found microplastics in the olfactory bulbs of 8 out of 15 cadavers.
Microplastics ranged from 5.5 to 26.4 micrometers in size and were primarily composed of polypropylene.
The olfactory bulb, responsible for detecting odors, may serve as a pathway for microplastics to reach the brain.
Previous research has found microplastics in various human tissues, including the brain, blood, and organs.
The study highlights the need for further investigation into the health implications of microplastic exposure.
