A concerning new study by the Autonomous University of Barcelona (UAB) has revealed that commercial tea bags release billions of microplastic and nanoplastic particles during brewing, raising serious questions about daily exposure to these contaminants through common food packaging. The research, published in Chemosphere journal, found that a single polypropylene tea bag releases approximately 1.2 billion micro- and nano plastic particles per milliliter of water. These particles average 136.7 nanometers in size – small enough to penetrate human cells.
