Chewing gum can shed hundreds of microplastics into your mouth

Researchers have recently uncovered a surprising new source of microplastics in our bodies: chewing gum. A pilot study presented at the American Chemical Society’s spring meeting revealed that a single piece of gum can release hundreds of polymer particles into our mouths, contributing to the growing issue of microplastic contamination. Not only are these particles potentially ingested by the chewer, but improper disposal of gum can also add to the environmental burden of microplastics.

Previous estimates suggested that humans consume tens of thousands of microplastic particles each year, primarily from plastic packaging, coatings, and small polymers that transfer onto food and beverages. However, the average gum consumer chews around 160-180 sticks per year, prompting researchers at the University of California, Los Angeles (UCLA) to investigate the microplastic content in gum.

In a preliminary study, a single volunteer tested 10 different brands of gum—five containing synthetic additives and five made with only natural ingredients. The volunteer chewed seven pieces of each gum brand consecutively for four minutes, with saliva samples collected every 30 seconds and analyzed for microplastic content. The results showed that both synthetic and natural gums released similar amounts of microplastics during chewing, with the majority of particles shed within the first few minutes.

On average, each gram of gum was found to contain at least 100 microplastic particles, potentially reaching up to 600 particles per gram. Extrapolating these findings, a single piece of gum could release up to 3,000 microplastics, and regular gum chewers may ingest around 30,000 microplastics annually. It is important to note that the study was limited to particles measuring at least 20-micrometers-wide, indicating that the actual amount of microplastics from gum could be much higher.

Despite the concerning findings, the researchers emphasize the importance of proper gum disposal to minimize environmental impact. While the plastic released into saliva represents only a fraction of the plastic content in gum, it is crucial to avoid littering or improper disposal of chewed gum. By raising awareness about the presence of microplastics in everyday products like gum, the study aims to encourage more mindful consumption habits and environmental stewardship.

In conclusion, the study sheds light on a previously overlooked source of microplastic exposure and underscores the need for further research and awareness in addressing the pervasive issue of microplastic pollution. By making informed choices and adopting responsible disposal practices, individuals can help reduce their contribution to the microplastic contamination of our bodies and the environment. The global pandemic caused by the novel coronavirus has brought about unprecedented changes in all aspects of our lives. From the way we work, socialize, and travel, to the way we shop for groceries, the impact of COVID-19 has been felt far and wide. One of the industries that has been significantly affected by the pandemic is the retail industry.

Retailers have had to adapt quickly to the changing circumstances brought about by the pandemic. With lockdowns and social distancing measures in place, many traditional brick-and-mortar stores have had to close their doors temporarily or permanently. This has forced retailers to shift their focus to online sales in order to stay afloat.

The shift to online shopping has been a challenge for many retailers, especially those who were not prepared for the sudden surge in demand for online services. Many retailers have had to invest in new technology and infrastructure to support their online operations, while also ensuring the safety and well-being of their employees and customers.

In addition to the shift to online shopping, retailers have also had to implement new health and safety protocols in their physical stores. This includes measures such as mandatory mask-wearing, social distancing markers, and increased cleaning and sanitation procedures. These measures have not only added to the operating costs of retailers but have also changed the way consumers interact with physical stores.

Despite these challenges, some retailers have found ways to thrive in the midst of the pandemic. For example, retailers that offer essential goods such as groceries and household items have seen a surge in demand as consumers stock up on supplies. Similarly, retailers that have embraced e-commerce and invested in their online presence have been able to reach a wider customer base and increase their sales.

Looking ahead, it is clear that the retail industry will continue to face challenges as the pandemic rages on. Retailers will need to continue to adapt to the changing circumstances and find innovative ways to connect with customers. Whether it’s through online sales, curbside pickup, or virtual shopping experiences, retailers will need to be flexible and agile in order to survive in the post-pandemic world. Only time will tell how the retail industry will evolve in the wake of COVID-19, but one thing is certain: the pandemic has forever changed the way we shop.
