There are serious worries about how microplastics may affect both human and animal health because it is common in our surroundings.
According to a recent study eating these microscopic plastic particles is causing them to enter human bodies and accumulate in the brains of people.
The study’s authors claim that swallowed microplastics travel to the brain, liver, and kidneys from the gut.
Skin contact, inhalation, or ingestion (by trophic transfer or contaminated food) could be the entry point.
“Our findings recommend that microplastic exposure can lead to metabolic changes in these tissues, indicating potential systemic effects. The implications of our findings for human health are substantial,” study author Marcus Garcia, PharmD, a postdoctoral fellow at the University of New Mexico College of Pharmacy said.
Plastic particles smaller than five millimeters in size are known as microplastics, and they have become a common environmental contaminant of food, water, and soil.
The authors of the study try to replicate human exposure to a similar level of microplastic ingestion. Through oral stomach feeding, mice were exposed to varying concentrations of polystyrene or mixed polymer microspheres.
The researchers looked for microplastics in the serum, brain, liver, kidney, and colon tissues of the mice after they were fed the microplastics.
Researchers found microplastics in the exposed mice’s liver, kidneys, and brain, which is concerning. This finding raises the possibility that microplastics can pass through the stomach and end up in other parts of the body.
Additionally, they discovered that the colon, liver, and brain had particular metabolic alterations following exposure to microplastics.
If microplastics or even smaller nanoplastics get inside the brain, they could interfere with its sensitive processes. Many concerns, such as aberrant protein failure, neuronal communication problems, and loss of brain cells, might result from this disruption.
The overall effect might be the onset or exacerbation of neurodegenerative illnesses such as Alzheimer’s or even issues related to a child’s brain development.
