A new study released by McGill University shows that a single nylon tea bag can release up to 11.6bn microplastics, a startling high number. This is due to plastic packaging being seeped in boiling water, degrading the plastic and leaching toxic substances directly into your tea.
Microplastics found in human placenta
Of course not all tea bags are made from fancy nylon, some and most are made from natural materials yet plastic is still used to seal the bags. Less microplastics are found in these tea bags, but its safe to say that with every cup of tea we are directly ingesting some if not too much microplastic. This could also explain how for the first time this year scientists found microplastics in human stool as well.
