'It is a threat to biodiversity, and we should be very concerned.'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.
In particular, the highest concentration of a single compound was found in a rock bass, which had 400 nanograms of norsertraline per gram of brain tissue.
Norsertraline is a metabolite of sertraline - the active ingredient in Zoloft, a drug that is used to treat depression, OCD, PTSD and other mental health disorders.
The study, which revealed that human antidepressants are building up in the brains of fish common to the Great Lakes region, was conducted at the Niagara River, which connects two of the Great Lakes, Lake Erie and Lake Ontario, via Niagara Falls This was in addition to many other compounds found in the same fish, including citalopram, the active ingredient in Celexa (an anti-depression drug), and norfluoxetine, a metabolite of the active ingredient in Prozac and Sarafem, which treat depression, OCD, bulimia, and panic disorder.
More than half of the fish brain samples has norsetraline levels of 100 nanograms per gram or higher, and many of the fish had a medley of other antidepressant drugs and metabolites in their brains.
'As a result, wildlife is exposed to all of these chemicals.
'Fish are receiving this cocktail of drugs 24 hours a day, and we are now finding these drugs in their brains.' Dr Singh says that the problem is exacerbated by sewage overflows that funnel large amounts of untreated water into rivers and lakes.
Dr Aga has spent her career developing techniques for detecting contaminants such as pharmaceuticals, antibiotics and endocrine disrupters in the environment.

Dr Aga says that wastewater treatment facilities have not kept pace with this growth, ignoring these drugs which are then released into the environment.
'These plants are focused on removing nitrogen, phosphorus, and dissolved organic carbon but there are so many other chemicals that are not prioritized that impact our environment,' says Dr Aga.
High concentrations of these drugs were detected in the brain tissue of 10 fish species in the Niagara River New research has revealed that human antidepressants are building up in the brains of bass, walleye and other fish common to the Great Lakes region.
