[This] should serve as a wake-up call

A recent study conducted by researchers at the University of Nebraska has revealed that microwaving plastics can release an alarming number of tiny plastic particles into our environment. In some cases, more than 2 billion nanoplastics and 4 million microplastics per square centimeter were found. The potential impact of these synthetic materials on our bodies is still unclear, which is cause for concern.

Judith Enck, a former EPA administrator and president of advocacy group Beyond Plastics, emphasized the need for the FDA to take a more proactive approach in light of this study. She believes that the findings should serve as a wake-up call, not only for new parents but for the regulatory agency as well.

The study conducted by Nebraska researcher Kazi Albab Hussain and his team involved microwaving FDA-approved plastic baby bottles. These bottles were filled with water and other liquids that simulated food, and then microwaved for three minutes. The results showed that the heating process led to the release of microplastics that could be ingested by children.

Hussain, who became a new dad during the study, acknowledged that completely avoiding the use of plastic for his baby was challenging. However, he was able to identify scenarios that caused a higher release of micro- and nanoplastics and avoid them. He believes that people should be informed about these scenarios and make wise choices regarding the use of plastics.

Microplastics are minuscule plastic particles that have been discovered in various environments, from the highest peaks to the deepest oceans. According to Henry Ford Health, a study found that 77% of people tested had microplastics in their blood. Some microplastics are made from PFAS, commonly known as “forever chemicals” due to their slow degradation. It is estimated that up to 97% of Americans have PFAS in their blood.

While the health impact of microplastics and PFAS is still being studied, it is reasonable to assume that they have negative effects on the body. Hussain stated that many studies, including theirs, have shown that the toxicity of micro- and nanoplastics is closely linked to the level of exposure. In their experiment, the researchers exposed kidney cells to the microplastics released during the microwaving of plastic bottles, and approximately 75% of the cells were killed. This suggests a potential link between microplastics and kidney damage.

To avoid microplastics, it is advised to refrain from microwaving plastics altogether. Hussain hopes that the development of a better plastic that releases fewer particles will be a possibility in the future. In the meantime, there are alternative products available, such as edible plastic-free food wraps, compostable coffee pods and tea bags, and glass baby bottles, which provide similar functionality without the presence of tiny plastic particles.

In conclusion, the research conducted by the University of Nebraska highlights the significant release of micro- and nanoplastics when plastics are subjected to microwave heating. The potential impact of these particles on our health is still being investigated. It is crucial for individuals and regulatory agencies to be aware of these findings and take proactive measures to minimize exposure to microplastics.
