- New research suggests hot drinks may be a more significant source of microplastics than previously realised.
- A University of Birmingham study found the highest concentrations of microplastics in hot tea and hot coffee among 155 common drinks tested.
- The research indicates that high temperatures and preparation processes for hot beverages contribute to increased microplastic levels.
- Hot tea in disposable cups contained the most microplastics, averaging 22 particles per cup, with more expensive teabags also leaching substantial amounts.
- The findings suggest that assessing microplastic exposure solely through drinking water may underestimate the overall risk, calling for more comprehensive dietary studies.
