Research from the Autonomous University of Barcelona in Spain found that individual tea bags steeped in boiling water can release billions of micro- and nanoplastic particles. Here's what to know.
Summary
A new study from Spain’s Autonomous University of Barcelona reveals that tea bags made from nylon, polypropylene, and cellulose release billions of micro- and nanoplastic particles when steeped in boiling water.
These particles, which can enter human intestinal cells, may pose health risks, potentially affecting the digestive, respiratory, endocrine, and immune systems.
Researchers urge regulatory action to mitigate plastic contamination in food packaging.
Consumers are advised to use loose-leaf tea with stainless steel infusers or biodegradable tea bags to minimize exposure.
No it doesn’t. This study is unscientific garbage and should be retracted.
Their “simulation” of making tea involved 300 teabags boiled in 600ml of water at 95 C while being stirred at 750rpm for an unspecified amount of time. They then took counts using undiluted samples of that liquid.
It isn’t clear why they chose such an absurd methodology, but it is absolutely spurious to draw conclusions from this about teabags used under normal conditions.
You want "compostable" or better, "home compostable". Biodegradable is a word that is completely twisted, and items that include plastics will use that word no matter how untruthful it is to the spirit of the meaning.
This is why I simply tear open the tea bags and dump them into a fine mesh stainless steel basket and set it in the cup.
I have yet to find loose leaf tea tasty enough to repeat buy but I do have 3-4 flavors of bagged tea I always keep stocked.
The biggest downside to doing my favorite bagged teas this way is it’s a pain to clean out the metal basket when I just want another cup the next day, but to me the trade off on sidestepping the microplastic issue is worthwhile
I think the new eu bottle caps as well(even when using milk cartons) becuse when you open it they usually have a piece sticking out on the cap that catches on the threads to keep it open, and sometimes i see small plastic pieces flying everywhere when i open one of them. Presumably the plastic catch is breaking pieces of the thread off.
