Antidepressants found in fish flowing into Cootes Paradise, making them vulnerable: study


Residue from antidepressant drugs flowing through the Dundas Wastewater Treatment Plant into Cootes Paradise is showing up in fish and apparently making them more vulnerable to predators, a new study has found. A team of researchers with Environment and Climate Change Canada and McMaster University found fish with elevated levels of serotonin in their blood plasma were more active and willing to explore than fish kept away from waste water treatment plant discharges. The exposed fish, she said, tended to avoid cautionary instincts such as keeping still after being startled. The researchers caged goldfish at various sites in Cootes Paradise and at a control site in Jordan Harbour, between Beamsville and St. Catharines on the shores of Lake Ontario. The analysis found several commonly prescribed antidepressants, known as serotonin uptake/reuptake inhibitors, in the blood plasma of the fish that were caged in Cootes downstream from the Dundas Wastewater Treatment Plant.
