NEW YORK, March 17: As plastic waste continues to accumulate in the environment, humans are unknowingly ingesting microplastics through drinking water and food, with detrimental effects on internal organs. A recent study published by Communications Biology highlights that the kidneys are particularly affected by these particles, which are absorbed through the digestive system.

Microplastics—tiny plastic particles less than 5 millimeters in size—are identified as the primary carriers of the environmental pollutant Benzo[a]pyrene (BaP) into the human body. While the exact pathways of absorption are still not fully understood, evidence suggests that BaP enters the body mainly through the intestines after oral ingestion, posing significant health risks.

The study also found that bottled water is a major source of microplastics, causing damage to the intestinal wall and kidneys, while triggering systemic inflammation. As microplastics are not naturally occurring and are manufactured by humans, they cannot be broken down by organisms, making them a persistent environmental hazard.

Microplastics are a growing problem due to their size, which makes them nearly impossible to clean up. These particles have been discovered in human and animal stomachs, in the air, soil, tap water, food, and drinks. Additionally, they are accumulating in oceans, harming coral reefs and other ocean ecosystems. While research is ongoing, the full scope of the risks to both human health and the environment remains unknown.

To mitigate the release of microplastics into the environment, reducing plastic use and recycling properly are essential steps. Simple actions, such as using reusable water bottles and containers instead of single-use plastics, and opting for reusable shopping bags instead of plastic ones, can significantly help reduce the production of microplastics. Supporting brands that use plastic-free packaging also contributes to minimizing the spread of these pollutants.

Scientists are actively working on solutions to combat the issue of microplastics, with the bioCap filter showing promising results in its development.

Although the full long-term effects of microplastics are still being studied, taking individual actions can help reduce the risks associated with these harmful particles.
