一项新研究发现，瓶装水中的塑料含量比之前估计的含量高出 100 倍。 A new study found that bottled water contains up to 100 times more plastic than previously estimated.
科学家发现，瓶装水中的塑料含量比之前估计的多出 100 倍，平均每升含有约 24 万个可检测到的塑料碎片。 Scientists have discovered that bottled water contains up to 100 times more plastic than previously estimated, with an average liter containing around 240,000 detectable plastic fragments. 研究人员通过使用经调谐使特定分子产生共振的激光探测样品，发现了称为纳米塑料的微小塑料碎片。 The researchers found microscopic pieces of plastic, called nanoplastics, by probing samples with lasers tuned to make specific molecules resonate.
