New study finds disposable tea bags release harmful microplastics into tea when steeped.

A new study in Chemosphere discovered that disposable tea bags release billions of microplastics when steeped, which can be absorbed by human intestinal cells. Common materials like nylon-6, polypropylene, and cellulose were found to leach these particles. The health impacts are still under study but may include organ damage and inflammation. Researchers advise using biodegradable tea bags or metal infusers to minimize exposure.
