Jonathan Lambert: 人类活动导致大量药物残留物进入河流和溪流等水体,这些药物残留物对水生动物,特别是鲑鱼的生存和行为造成了潜在的威胁。实验室研究已经表明,某些药物会改变鱼类的行为模式,例如使它们更具攻击性或更倾向于冒险。然而,这些药物对野生鱼类行为的影响仍然有待进一步研究。 Jack Brand: 我们进行了一项研究,将抗焦虑药物和止痛药植入瑞典的野生大西洋鲑鱼体内,并追踪它们的迁移行为。研究结果显示,抗焦虑药物氯氮卓能够提高鲑鱼的迁移成功率,使它们更快地通过水力发电大坝等障碍物。然而,这种药物也使鲑鱼更孤僻,更倾向于单独行动,这可能会增加它们被捕食的风险。 Olivia Simons: 水力发电大坝的涡轮机对鲑鱼的迁移构成严重威胁,可能导致受伤甚至死亡。因此,鲑鱼在迁移过程中需要谨慎小心,避免冒险。 Karen Kidd: 目前,我们对多种药物混合污染对鱼类的影响知之甚少。各种药物的混合作用可能会对鱼类的健康和行为产生复杂的影响,这需要进一步的研究来揭示。 Jonathan Lambert: 除了研究药物对鱼类行为的影响之外,我们还需要关注如何减少药物污染。改进污水处理厂的过滤系统,以及研发更环保的药物,都是减少药物污染的有效途径。

Chapters
The episode explores the impact of pharmaceutical pollution on aquatic life, focusing on a study where scientists implanted anti-anxiety drugs into salmon to observe their behavior during migration. The results were surprising, showing that the drugs affected the salmon's migration success and social behavior.
  • Researchers found over 900 pharmaceutical ingredients in waterways.
  • A study implanted anti-anxiety and pain medication into salmon.
  • The anti-anxiety drug improved migration success but decreased shoaling behavior.

A fish walks into a pharmacy ... well, not exactly. Fish aren't being prescribed anti-anxiety drugs. But they *are *experiencing the effects. Researchers have found more than 900 different pharmaceutical ingredients in rivers and streams around the world, though they're not yet sure how this could change the behavior of fish and other aquatic animals in the wild."We can't, you know, dump a bunch of pharmaceuticals into the river," says Jack Brand), biologist at the Swedish University of Agricultural Sciences. Instead, Jack's team did the next best thing – with some surprising results.**This episode was reported by NPR science correspondent Jon Lambert).
