Plastic teabags, according to a new study, dump billions of pieces of microplastic into their water.
Researchers at McGill University in Canada analyzed the effects of placing four different commercial teabags in boiling water.
They found that a single bag dispenses approximately 11.6 billion microplastic particles and 3.1 billion even smaller nanoplastic particles into the cup – a thousand times higher than the amount of plastic previously contained in other foods and beverages.
the team removed the tea from the bags to avoid compromising the results before boiling the bags in water to simulate the tea making process.
Scientists found microplastics in different foods, but less It was investigated whether they can be shed in water during the brewing of tea and other hot drinks.
Many tea producers use polypropylene to seal their bags.
"We urgently need to know more about the health effects of microplastics because they are present everywhere – including in our drinking water," Dr. Maria Neira, Director of the Department of Public Health, Environment and Social Determinants of Health at WHO.
