Research reveals tea bag materials release microplastics into water, indicating varying stability and toxicity among polymers.

Microplastics ranging from 200 nm to 1 µm are released from tea bags, with an average size of around 600 nm.
The concentration of released microplastics increases with higher temperatures and longer brewing times, reaching up to 170 billion particles per liter for cellulose.
Synthetic polymer particles maintain stability despite the presence of natural enzymes, while cellulose particles are readily degraded.
Released particles exhibit a negative surface charge, indicating no cytotoxic effects on the Caco-2 epithelial cell line.

Yaroslavov et al. (2025) studied this question.
