Chewing gum can shed microplastics into saliva, pilot study finds (acs.org)
SAN DIEGO, March 25, 2025 — Plastic is everywhere. And many products we use in everyday life, such as cutting boards, clothes and cleaning sponges, can expose people to tiny, micrometer-wide plastic particles called microplastics. Now, chewing gum could be added to the list. In a pilot study, researchers found that chewing gum can release hundreds to thousands of microplastics per piece into saliva and potentially be ingested.

Antioxidants in fruits, flowers may counteract harmful effects of microplastics (theguardian.com)
Antioxidants that give fruits and flowers their vibrant colors seem to counteract some of the most dangerous reproductive system effects of exposure to microplastics, such as decreased fertility, and could ultimately be used in developing treatments, new peer-reviewed research shows.

Commercial tea bags release microplastics, entering human cells (medicalxpress.com)
UAB research has characterized in detail how polymer-based commercial tea bags release millions of nanoplastics and microplastics when infused. The study shows for the first time the capacity of these particles to be absorbed by human intestinal cells, and are thus able to reach the bloodstream and spread throughout the body.

Car tires shed a quarter of all microplastics in the environment (phys.org)
Every year, billions of vehicles worldwide shed an estimated 6 million tons of tire fragments. These tiny flakes of plastic, generated by the wear and tear of normal driving, eventually accumulate in the soil, in rivers and lakes, and even in our food. Researchers in South China recently found tire-derived chemicals in most human urine samples.
