In recent years, numerous studies have warned of the presence of plastic in our human body. When we eat, when we use cosmetics, when we cook, pollutants are everywhere. According to the findings of a new study published September 16 in the journal JAMA Network Open, microscopic microplastics are entering our brains… when we breathe.
In this study, German and Brazilian researchers report that eight out of 15 adults autopsied had microplastics detected in the olfactory bulbthe olfactory center of the brain. Specifically, 16 particles and fibers of synthetic polymer were identified. While microplastics have already been found in the lungs, intestines, liver, blood, testicles and even human sperm, it was long thought that the body’s protective blood-brain barrier could prevent particles from entering the brain.
But the results of this new research suggest that there is “a potential pathway for microplastics to be translocated to the brain” via the olfactory bulb. “Since much smaller nanoplastics enter the body more easily, the total level of plastic particles could be much higher. What is concerning is the ability of these particles to be internalized by cells and change the way our body works “, points out Thais Mauad, associate professor of pathology at the University of Sao Paolo in Brazil. In nearly 44% of cases, the plastic was polypropylene, one of the most common plastics, used in everything from packaging to clothing and home accessories, the statement reports.
But how do microplastics enter the brain?

“When you breathe through your nose, your olfactory nerve directly samples particles and responds to the particles that you inhale as a direct sensory mechanism,” explained Dr. Wells Brambl, senior professor of medical toxicology at Long Island Jewish Medical Center in New York City. He added, “The fact that there is no blood-brain barrier there leads to direct access to the brainand more importantly, just above the olfactory nerve are the frontal and prefrontal lobes, where we think the seat of consciousness is,” added Dr. Brambl, who was not involved in the study.
Further studies should enable us to identify precisely the dangerous potential of these microplastics. “Given the potential neurotoxic effects caused by microplastics in the brain and the widespread environmental contamination by plastics, our results should raise concerns in the context of the increasing prevalence of neurodegenerative diseases” such as Parkinson’s, ALS and other diseases, the researchers report.

Microplastics Found in Human Brains: The Alarming Consequences of Plastic Pollution
Introduction
The presence of plastic in our daily lives has become an undeniable reality. From the food we eat to the cosmetics we use, plastic pollutants are omnipresent. Recent studies have sounded the alarm on the alarming levels of plastic in our bodies, and now, a new study takes it to a whole new level: microplastics have been found in our brains.
The Shocking Study
A recent study published in the journal JAMA Network Open reveals that microscopic microplastics are entering our brains through the air we breathe. German and Brazilian researchers found that 8 out of 15 adults autopsied had microplastics detected in the olfactory bulb, the olfactory center of the brain. Specifically, 16 particles and fibers of synthetic polymer were identified. This groundbreaking discovery raises concerns about the potential impact of microplastics on human health.
The Blood-Brain Barrier Undermined
For a long time, it was believed that the body’s protective blood-brain barrier could prevent particles from entering the brain. However, this study suggests that microplastics can bypass this barrier through the olfactory bulb, providing a potential pathway for microplastics to enter the brain. This is particularly concerning, as the ability of these particles to be internalized by cells and change the way our body works is still not fully understood.
The Most Common Plastics
In nearly 44% of cases, the plastic detected was polypropylene, one of the most common plastics used in everything from packaging to clothing and home accessories. This raises questions about the widespread use of plastics in our daily lives and their potential impact on our health.
How Do Microplastics Enter the Brain?
Dr. Wells Brambl, senior professor of medical toxicology at Long Island Jewish Medical Center in New York City, explained that when we breathe through our nose, our olfactory nerve directly samples particles and responds to the particles that we inhale as a direct sensory mechanism. The fact that there is no blood-brain barrier in this area leads to direct access to the brain, making it a potential entry point for microplastics.
The Alarming Consequences
The presence of microplastics in our brains raises a host of concerns about the potential impact on human health. Microplastics have already been linked to a range of health problems, including inflammation, oxidative stress, and even cancer. The fact that they can enter our brains through the air we breathe raises the stakes, as our brains are vulnerable to the subtle changes that microplastics can cause.
What Can We Do?
The discovery of microplastics in our brains is a wake-up call to take action against plastic pollution. Here are some steps we can take to minimize our exposure to microplastics:
Reduce our use of single-use plastics
Choose products with minimal packaging
Avoid microbeads in cosmetics and personal care products
Use air purifiers to reduce particulate matter in the air
Support policies that promote sustainable waste management and plastic reduction
Conclusion
The presence of microplastics in our brains is a stark reminder of the urgent need to address plastic pollution. As we continue to uncover the alarming consequences of plastic pollution, it is essential that we take collective action to reduce our plastic footprint and protect our health. The future of our planet and our well-being depend on it.

Microplastics Found in Human Brains: The Alarming Consequences of Plastic Pollution
Introduction
The presence of plastic in our daily lives has become a ubiquitous reality. From the food we eat to the air we breathe, microplastics have infiltrated every aspect of our environment. Recent studies have warned of the presence of plastic in our human body, and a new study published in the journal JAMA Network Open has found that microscopic microplastics are entering our brains through the air we breathe.
The Study: Microplastics in the Olfactory Bulb
German and Brazilian researchers have discovered that eight out of 15 adults autopsied had microplastics detected in the olfactory bulb, the olfactory center of the brain.

What Health Risks Are Associated with Microplastics Found in Human Brains?
The presence of microplastics in the brain raises concerns about the potential neurotoxic effects caused by microplastics. The researchers report that the findings should raise concerns in the context of the increasing prevalence of neurodegenerative diseases such as Parkinson’s, ALS, and other diseases. Further studies are needed to identify the dangerous potential of these microplastics and the potential long-term effects on human health.
The Alarming Consequences of Plastic Pollution
The discovery of microplastics in human brains is a stark reminder of the alarming consequences of plastic pollution. The widespread environmental contamination by plastics has led to a situation where humans are unknowingly ingesting and inhaling microplastics on a daily basis. The potential health risks associated with microplastics in the brain are still unknown, but the study’s findings suggest that it is essential to take immediate action to reduce plastic pollution and protect human health.
Conclusion
The presence of microplastics in human brains is a wake-up call for all of us. The study’s findings highlight the need for immediate action to reduce plastic pollution and protect human health. As individuals, we can make conscious choices to reduce our plastic usage, and as a society, we must work together to create a plastic-free future.
