科学家发现瓶装水中含有微量的塑料颗粒，对健康构成威胁。 Scientists have discovered that bottled water contains tiny amounts of plastic particles that pose a health risk.

一项新研究发现，瓶装水中含有近 25 万个看不见的塑料碎片，即纳米塑料，对健康构成重大风险。 A new study has found that bottled water contains nearly a quarter million invisible fragments of plastic, known as nanoplastics, posing significant health risks. 这项发表在《美国国家科学院院刊》杂志上的研究发现，每升瓶装水中含有约 24 万个塑料碎片，其中 90% 是纳米塑料，它们小到足以穿透人体细胞、进入血液并影响器官。 Published in the journal Proceedings of the National Academy of Sciences, the study identified around 240,000 plastic fragments per liter of bottled water, with 90% being nanoplastics, which are small enough to penetrate human cells, enter the bloodstream, and impact organs. 研究人员使用新改进的技术来检测瓶装水中的这些微小颗粒。 The researchers used newly-refined technology to detect these minute particles in bottled water.
