**Barcelona, Spain** – A new study from the Autonomous University of Barcelona (UAB) has revealed that commercially available tea bags release billions of microplastics and nanoplastics into tea infusions. The research, published in [insert publication details here if available], found that the polymer materials used in tea bag construction – nylon-6, polypropylene, and cellulose – leach significant quantities of these particles into the brewed beverage.

Researchers analyzed several commercially available tea bags and found alarmingly high levels of particle release. Polypropylene tea bags, for instance, released approximately 1.2 billion particles per milliliter, averaging 136.7 nanometers in size. Cellulose bags released around 135 million particles per milliliter (244 nanometers average), while nylon-6 bags released 8.18 million particles per milliliter (138.4 nanometers average).

These microplastics and nanoplastics, according to the study, are small enough to be absorbed by human intestinal cells and potentially enter the bloodstream, raising concerns about their impact on human health. The study highlights food packaging as a major source of micro- and nanoplastic contamination, with ingestion and inhalation identified as primary exposure routes.

“We have managed to innovatively characterize these pollutants with a set of cutting-edge techniques, which is a very important tool to advance research on their possible impacts on human health,” said microbiologist Alba Garcia-Rodriguez from UAB. The research underscores the need for further investigation into the long-term health effects of microplastic and nanoplastic ingestion and calls for increased awareness of this potential health hazard associated with common everyday items like tea bags.
