In December, researchers from the Autonomous University of Barcelona in Spain published a new study in the journal Chemosphere showing that individual tea bags steeped in boiling water can release micro- and nanoplastic particles, which are then ingested by the drinker. And it's not just a few particles here or there. The researchers found that the bags can release particles in the billions, adding to the body of work already out there presenting the dangers of microplastics from tea bags.
