Discovered billions of microscopic particles in tea filter bags
When drinking a cup of tea, the amount of plastic particles in the body 200,000 times the total amount of micro plastic a person consumes each year.
When drinking a cup of tea, the amount of plastic particles in the body 200,000 times the total amount of micro plastic a person consumes each year.
Microplastics are smaller than 5mmg, capable of penetrating into food, water and air absorbed by humans daily.
It is estimated that the average person inhales 74,000 microplastics every year. Meanwhile, a plastic tea filter bag releases about 11.6 billion micro plastic particles and 3.1 billion nanoplastic particles in the tea cup when brewed with hot water 95 degrees C.

This is the result of a team of scientists McGill University, after soaking empty tea bags, washed, in hot water 95 degrees C. Results of analysis by microscopy and spectrophotometer, most The microplastics in the tea sample were all PET and nylon. These are the materials used in the production of tea bags to keep the tea bag in shape.
According to the World Health Organization (WHO), the effects of microplastics on human health have not been proven, but other studies are needed to clarify this relationship.
The team also advises people to use paper or powdered tea bag filter, to prevent possible health effects as well as minimize the "micro-particles" released into the environment.
The research results have just been published in Environmental Science & Technology .
