New research conducted at The University of Buffalo has shown some interesting results. Studies conducted on fish in local waters, specifically the Niagara River, show high levels of certain human antidepressants

According to the study,  the chemicals are being released into the river by wastewater plants.

"These drugs could affect fish behavior. We didn't look at behavior in our study, but other research teams have shown that antidepressants can affect the feeding behavior of fish or their survival instincts. Some fish won't acknowledge the presence of predators as much."

The fish that contained the largest amount of the human antidepressants were Rock Bass.

Randolph Singh, PhD was quoted in the release from UB:

"The levels of antidepressants found do not pose a danger to humans who eat the fish, especially in the U.S., where most people do not eat organs like the brain," Singh says. "However, the risk that the drugs pose to biodiversity is real, and scientists are just beginning to understand what the consequences might be."
