Fish swimming in water with a trace of the anti-depressant Prozac did not adopt a cheery disposition. Instead, they became edgy, aggressive and some even killed their mates.
The fish were subjected to traces of the drug by a research group at the University of Wisconsin-Milwaukee that examined how environmental exposure to the medication altered the behavior of fathead minnows, a common fish found throughout the Midwest.
Lead researcher Rebecca Klapper says that this experimental setup could actually be a reflection of the fishes’ reality.
The human body does not absorb medications 100 percent, so a trace amount is excreted in urine. Water treatment centers are unable to completely filter out all of those contaminant and can trickle down and affect the wildlife. Klapper sees the minnows as a way to gauge the long-term effects of Prozac in humans.
