Paper cups are leaching microplastics into coffees, tests show测试表明，纸杯会将微塑料渗入咖啡中。
Scientists have found that millions of plastic particles, some of them a thousand times thinner than a hair, are released into the body as the hot drink wears away at the cup's plastic lining.

Concerns about the environmental and health effects of plastic packaging have prompted a shift to paper, wood and other natural materials in recent years, amid much research showing microscopic plastic shards turning up in human organs and blood.
But even disposable coffee cups seemingly made of paper are not safe, it seems, going by tests carried out at the University of Queensland (UQ), where scientists have found that millions of plastic particles, some of them a thousand times thinner than a hair, are released into the body as the hot drink wears away at the cup's plastic lining.

你的“纸质”咖啡杯里可能漂浮着数百万个塑料微粒，其中一些微粒极其微小，比人类头发丝还要细一千倍。——克里斯汀·克洛斯/德新社
近年来，由于大量研究表明，微小的塑料碎片出现在人体器官和血液中，人们对塑料包装对环境和健康的影响日益关注，促使人们转向使用纸张、木材和其他天然材料。
但昆士兰大学 (UQ) 进行的测试表明，即使是看似用纸制成的一次性咖啡杯也不安全。科学家发现，当热饮腐蚀杯子的塑料内衬时，数百万个塑料颗粒（其中一些比头发丝还要细一千倍）会释放到人体中。
