Chewing Gum Identified as Significant Source of Microplastics in Human Saliva
- Researchers from the University of California, Los Angeles found that chewing one piece of gum can release hundreds to thousands of microplastic particles into saliva, which may then be swallowed.
- On average, one gram of gum releases 100 microplastic pieces, with some pieces shedding over 600.
- The researchers emphasized concerns about the environmental impact of discarded chewing gum and urged people to dispose of it properly.
- The study suggests that while microplastics may enter the body through gum, there is no direct evidence showing that they are harmful to health.
