Microplastics can invade the olfactory bulb of the human nose, which transmits smells to the brain, a new study found.

Microplastics are inescapable. These miniscule plastic particles have been found at ancient archaeological sites, in freshly fallen snow on Antarctica, at the top of Mount Everest and deep in the Mariana Trench.

Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected within their brain's smell centers, the olfactory bulb. The particles were likely breathed in over a lifetime,

A new study in Brazil found microplastics in the brain tissue of cadavers, pointing to the olfactory bulb as a point of entry. Dr. Natalie Azar explains how microplastics can enter the body and what it means for human health.

Evidence of microplastics, which are in everything from clothes to water bottles, has been found in human brains, researchers said.

The study published on Monday in the journal JAMA Network Open revealed that eight out of 15 autopsied adults in Germany and Brazil had microplastic inside the brain’s olfactory bulb. Researchers from the University of Sao Paulo in Brazil said the tiny plastic particles,

Microplastics have been found in brain tissue above the nose, suggesting a likely passageway for microscopic plastic shards and fibers to enter the brain after already being discovered in nearly every organ in the human body,

Microplastics infiltrate human bodies, threatening our health. Recent studies suggest widespread environmental contamination.
