Chewing gum has been found to release hundreds to thousands of microplastics into saliva, according to a new pilot study. The research, presented at the American Chemical Society Spring Meeting, tested five brands of synthetic gum and five brands of natural gum, all of which are commercially available.
The study’s findings suggest that both synthetic and natural gums release similar amounts of microplastics, with an average of 100 microplastics released per gram of gum.The researchers used a dye called Nile Red to stain the microplastics, making them easier to see. However, some experts have raised concerns about the reliability of this method, citing potential issues with lab contamination and measurement error.
Despite these concerns, the study’s findings are significant, suggesting that chewing gum could be a previously overlooked source of microplastic exposure.The study’s lead researcher, Sanjay Mohanty, emphasized that the goal of the research is not to alarm people, but rather to raise awareness about the potential sources of microplastic exposure in everyday life.
Mohanty noted that scientists still don’t know the full impact of microplastics on human health, but that reducing exposure is a precautionary measure worth taking.The study’s findings have implications for consumers and manufacturers alike. While the amount of microplastics released by chewing gum may seem small, it can add up over time. Experts recommend proper disposal of used gum and exploring alternative products that are free from microplastics.
