Some premium tea bags might be leaving billions of microscopic plastic particles in your cup, new research suggests.
    Canadian researchers found that some plastic tea bags shed high levels of microplastics into water.
    Microplastic have widely been found in the environment, in tap and bottled waters, and in some foods.
    The World Health Organization (WHO) says such particles in drinking water do not appear to pose a risk.
