Scientists are highlighting more methods that microplastics infiltrate the human body. While normal sources include shampoo bottles, plastic utensils, fabrics, cutting boards and cleaning sponges, researchers have now found that the chewing gum can release hundreds of microplastics per piece in saliva, possibly leading to the ingestion.

However, “Our goal is not in danger to anyone,” said Sanjay Mohanty, the leading investigator of the project and an engineering professor at the University of California, Los Angeles (UCLA).

“Scientists don’t know whether microplastics are insecure for us or not. There are no human tests. But we know that we are aware of plastic in everyday life, and that is what we wanted to investigate here,” said Mohanty.

Researchers presented their results at the spring meeting of the American Chemical Society (ACS).

UCLA researchers analyzed synthetic and natural chewing gums to measure how many microplastics are released during chewing.

He tested each type of five brands and found that both released the same amount of plastic particles. On average, 100 microplastic was released per gram of gum, some pieces were released as 600 microplastic per gram.

A specific piece of glue is between 2 and 6 grams, which means that a single piece can release up to 3,000 microplastic particles.

If an average person chews about 160 to 180 small rods per year, they can complete around 30,000 plastic particles annually, which can greatly increase their overall microplastic exposure.

The study found that most plastic particles separate from gum within the first two minutes of chewing due to friction, not due to breaking them due to saliva.

After eight minutes, 94% of the total plastic particles was already released.

Plastic includes common materials used in packaging and synthetic rubber products found plastic, polyelephin, polyethylene terefthelets, and polystyrents.

While the health effects of microplastic consumption are still being studied, animal research suggests possible risks.

Experts recommend to reduce the exposure until scientists fully understand the impact on humans. A way to limit microplastic intake from gum is to chew a piece for a long time with a new one with a new time.

Beyond health concerns, improperly abandoned gum also contributes to environmental plastic pollution. Researchers emphasize the importance of proper settlement to prevent further contamination.
