Your Tea Bag Is Likely Releasing Billions of Microplastic Particles, According to a New Study

Research from the Autonomous University of Barcelona in Spain found that individual tea bags steeped in boiling water can release billions of micro- and nanoplastic particles. Here's what to know.

Summary

A new study from Spain’s Autonomous University of Barcelona reveals that tea bags made from nylon, polypropylene, and cellulose release billions of micro- and nanoplastic particles when steeped in boiling water.

These particles, which can enter human intestinal cells, may pose health risks, potentially affecting the digestive, respiratory, endocrine, and immune systems.

Researchers urge regulatory action to mitigate plastic contamination in food packaging.

Consumers are advised to use loose-leaf tea with stainless steel infusers or biodegradable tea bags to minimize exposure.

    Consumers are advised to check whether tea bags in their region are even made of these materials.

    Edit: Also, “billions”? The cookie warning is borked on the foodandwine.com article so I can’t read it but: https://www.dpa-international.com/trends-and-features/urn:newsml:dpa.com:20090101:250109-99-540705/ “Tea bags releasing ‘millions’ of microplastics into tea, study shows” - where does that difference come from?

      From the article:

      To come to this conclusion, the team tested tea bags made from nylon-6, polypropylene, and cellulose, all typical packaging for teas. They found that when brewing tea, “polypropylene releases approximately 1.2 billion particles per milliliter, with an average size of 136.7 nanometres; cellulose releases about 135 million particles per milliliter, with an average size of 244 nanometres; while nylon-6 releases 8.18 million particles per milliliter, with an average size of 138.4 nanometres.”
