Your Cup of Tea Could Contain Billions of Microplastics From One Source
- Latest findings show the first boil in a polypropylene kettle can release billions of plastic particles into water.
- The study found hard water and repeated boiling reduced particle release over time.
- Even after 150 boils, substantial nanoparticle levels persisted in some conditions.
- Researchers urge clearer product labeling and consumer warnings about plastic particle release.
- The NPJ Emerging Contaminants study supports ongoing work to assess health risks of nanoplastics in beverages.
