Another call for improvements to U-S wastewater treatment plants along the Niagara River.
The call comes after scientists at University of Buffalo, discovered high concentrations of anti depressant drugs in the brains of fish in the river.
Study author Doctor Diana Aga, says wastewater facilities focus on removing nitrogen, phosphorous, and organic carbons but neglect to prioritize human chemical compounds.
Co author Randolph Singh tells UB News other studies have shown that anti-depressants can effect the feeding behaviour of the fish or their survival instincts.
Singh adds while humans can safely eat the fish, degrading biodiversity in the river is a major concern.
The Niagara Falls, New York water board has been under fire for releasing millions of gallons of untreated wastewater into the river this summer, some of those releases were due to overflows from heavy rains.
The releases made headlines after one discharge at the end of July turned the water in the lower Niagara River black.
