Drug pollution alters salmon migration

Study reveals commonly detected environmental levels of clobazam -- a medication often prescribed for sleep disorders -- increased the river-to-sea migration success of juvenile salmon in the wild. The research team employed slow-release pharmaceutical implants and animal-tracking transmitters to monitor how exposure to clobazam and the opioid painkiller tramadol -- another common pharmaceutical pollutant -- affected the behaviour and migration of juvenile Atlantic salmon (Salmo salar) in Sweden's River Dal as they migrated to the Baltic Sea.
