A recent study conducted by researchers at the University of Birmingham and published in the journal "Science of the Total Environment" has raised alarming concerns about microplastics in beverages. It found that hot tea contains the highest amount of microplastics, with up to 60 microplastic particles per liter. According to Professor Mohamed Abdallah, this translates roughly to about 12 to 15 particles in a typical cup of tea, significantly higher than those found in energy drinks or sodas, which have 25 and 17 particles per liter, respectively.

The study highlights that the high temperatures of the beverage can accelerate the release of these plastic particles. This poses additional risks particularly with takeout paper cups that have a plastic lining, raising the microplastics concentration up to 22 particles per serving. In contrast, when tea is served in glass or ceramic cups, the number of microplastic particles is approximately 14 per serving. Professor Abdallah explains that microplastics are tiny fragments that come from the breakdown of larger plastic products or are specifically manufactured for certain products.

The findings of this study could have significant health implications, particularly as many people unknowingly consume high levels of microplastics through their daily beverages. The prevalence of microplastics in hot tea underscores the need for greater awareness and potential regulatory measures to protect consumers from these environmental pollutants.
