Cocaine in Water Makes Fish Swim Farther
Description
Griffith University researchers discovered that cocaine traces in water cause juvenile Atlantic salmon to swim up to 1.9 times farther each week, covering an extra 12.3 kilometers in a lake. This metabolite, benzoylecgonine, enters rivers and lakes through human wastewater, with urban areas having higher levels due to more people and runoff. The study, conducted in Swedens Lake Vattern, found that this shift in fish behavior could disrupt ecosystems and natural roles, such as feeding or migrating patterns. While human health risks may be skipped, nature is feeling the impact of our waterways being laced with human medications daily.
