Microplastics, tiny particles of plastic less than five millimeters in size, have been found in human brains for the first time. A recent study from the United States discovered microplastics in brain samples taken from deceased individuals in Albuquerque, New Mexico. The findings are concerning, as they suggest that people may be chronically exposed to these particles through their diet and environment.
Microplastics can enter the body through contaminated food and water, as well as airborne particles. Once inside, they can move into the bloodstream and travel to various organs, including the brain. While the study has not been independently verified, it adds to growing concerns about the impact of microplastics on human health.
The researchers found that up to 30 times more microplastics were present in brain samples than in liver or kidney samples. They hypothesized that this could be due to high blood flow to the brain or the liver and kidneys being better equipped to deal with external toxins.
Microplastics are difficult to study due to their small size, but researchers are beginning to use complex instruments that identify the chemical composition of microplastics in a sample. The most common type of plastic found in this study was polyethylene, which is widely used for everyday products like bottle caps and plastic bags.
While this study is important, it is still considered a “pre-print” and has not been independently verified by other scientists. However, the findings suggest that microplastics may be more widespread than previously thought and could potentially pose risks to human health.
To minimize exposure, experts recommend avoiding foods and drinks packaged in single-use plastic or reheated in plastic containers, as well as minimizing synthetic fiber exposure at home and in clothing. Reducing overall plastic waste can also help reduce the amount of microplastics that end up in the environment.
As research continues to unfold on the impact of microplastics on human health, it is essential to take steps to reduce exposure and mitigate potential risks.
