Summary
A study found that disposable plastic cups can release thousands of microplastic particles into hot drinks like coffee and tea. The researchers discovered that heat increases the release of microplastics, and the material of the cup matters. This research highlights potential health concerns as these tiny plastic particles can enter the human body.
Key Facts
- Disposable plastic cups can release microplastics into drinks.
- Heat makes more microplastics come out of plastic cups into drinks.
- Microplastics are tiny plastic bits, from the size of dust to sesame seeds.
- The study found that more microplastics are released at higher temperatures.
- Plastic-lined paper cups release fewer microplastics than all-plastic cups.
- Soaking time, or the time a drink stays in a cup, didn't affect microplastic release as much as initial heat.
- Around 500 billion single-use cups are used globally each year.
- Microplastics can enter the body through drinking or breathing.
