Through diet, microplastics accumulate much more in the brain than in the liver and kidneys.

The size of these microplastics can be less than 5 millimeters or 1 nanometer. These plastics accumulate inside the body through food and drinks. Over the last 8 years, excess plastic has accumulated in the brain.

According to CNN’s report, in 2024, a corpse was thoroughly tested in a laboratory. Then, research was conducted on microplastics. In which the age of this person was 45 or 50 years old.

It was found that 4,800 micrograms of plastic had accumulated in the person’s brain. This means that today our brain is 99.5% brain and the rest is plastic.

Matthew Campen, Regents Professor of Pharmaceutical Sciences at the University of New Mexico in America and lead author of the study, said plastic has been accumulating at a faster rate in recent years than in 2016. As a result, the risk of disease has increased.

Small plastic particles have a very harmful effect on the brain. Through the cadavers test, it was found that much more plastic accumulated in the brain than in the kidneys and liver.
