Nanoplastics Are Entering Our Bodies

From Observatory

Plastic, that ubiquitous material that surrounds us, has now found its way into our bodies. Nanoplastics, minuscule particles of plastic, are infiltrating our air, water, and food, raising concerns about their impact on human health.

The presence of nanoplastics in the air we breathe is a growing concern. Tiny plastic fibers, fragments, foam, and films are constantly being shed from plastic products and floating in the atmosphere. These particles are carried by wind and storms for miles before being deposited back on Earth, permeating the air of major cities like Paris, London, and Dongguan. Particularly dangerous are the particles shed from synthetic tires, which contain toxic materials and have been linked to the decline of Coho salmon in the U.S. Pacific Northwest.

Researchers have found evidence of nanoplastics in human lungs, with potential health implications. Scientists from Aalborg University in Denmark conducted a study using a mechanical lung system that emulates human breathing, confirming that plastic particles can enter our airways and potentially cause damage. Other researchers have also pointed out the need for systematic research on the health effects of nanoplastic inhalation, highlighting the potential for chronic inflammation and respiratory problems.

Plastic pollution is not limited to the air; it has infiltrated our water and food systems as well. Studies have detected microplastics, including nanoplastics, in fish, shellfish, packaged meats, processed foods, sea salt, soft drinks, tap water, and even bottled water. These particles have also been found in conventionally grown fruits and vegetables. The average person unknowingly ingests thousands of microplastic particles each year, with higher numbers for those who regularly consume bottled water.

Plastic’s impact on the environment extends beyond nanoplastics. The entire lifecycle of plastic, from extraction to disposal, emits toxic chemicals that pollute the air, soil, water, and ecosystems. Underserved communities, including marginalized groups, are disproportionately affected by plastic pollution and suffer the consequences of environmental injustice.

While the long-term effects of plastic on human health are still unclear, studies on laboratory animals and marine wildlife have shown toxic effects. Nanoplastics smaller than 100 nanometers have been found to cause inflammation, toxicity, and neurological changes in animals.

In conclusion, nanoplastics are making their way into our bodies through the air we breathe, the water we drink, and the food we eat. The implications for human health are a cause for concern, and further research is needed to understand the full extent of the problem. Plastic pollution, in all its forms, poses a significant threat to the environment and exacerbates social injustices. It is crucial that we address this issue and work towards sustainable solutions to mitigate the harm caused by plastic in our lives.
