塑料咖啡杯将数以百万计的微塑料放入热饮中,特别是在加热时。 Plastic coffee cups release millions of microplastics into hot drinks, especially when heated.

取走的咖啡杯,特别是塑料杯,将数千微塑料微粒释放到热饮料中,热量大幅增加。 Takeaway coffee cups, especially plastic ones, release thousands of microplastic particles into hot drinks, with heat significantly increasing shedding. 一项研究发现,在装满热液时,每升释放800万颗粒的所有塑料杯,比冷饮增加了33%。 A study found all-plastic cups released up to 8 million particles per liter when filled with hot liquid, a 33% increase from cold drinks. 塑料线纸杯释放的颗粒较少,但仍释放出微塑胶。 Plastic-lined paper cups released fewer particles but still shed microplastics. 更粗糙的表面和热柔软的塑料,促进粒子的释放。 Rougher surfaces and heat soften plastic, promoting particle release. 专家建议使用可重复使用的不锈钢、陶瓷或玻璃杯,并在倾注以降低接触之前略微冷却饮料。 Experts recommend reusable stainless steel, ceramic, or glass cups, and cooling drinks slightly before pouring to reduce exposure.
