For the first time, scientists have detected microscopic microplastics lodged in the human brain. 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.

For the first time, scientists have detected microscopic microplastics lodged in the human brain. 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, since tiny floating microplastics are ubiquitous in the air.

The particles were likely breathed in over a lifetime, since tiny floating microplastics are ubiquitous in the air.

Although microplastics have already been found in human lungs, intestines, liver, blood, testicles and even semen, it had long been thought that the body’s protective blood-brain barrier might keep the particles out of the brain.

However, the new study suggests that there’s “a potential pathway for the translocation of microplastics to the brain” via the olfactory bulb.
