Your Cup of Tea Could Contain Billions of Microplastics From One Source

Researchers at the University of Queensland found that new polypropylene kettles can release millions of plastic nanoparticles per milliliter into boiling water.

The contamination drops after repeated boils, and hard tap water can also reduce shedding by leaving mineral buildup inside the kettle.

The study suggests a common household appliance may be an overlooked source of microplastic exposure.

Clearer product labeling and simple steps could help reduce how much plastic people ingest through hot drinks like tea.
