A new study by researchers at the University of Montana found that the pollutants from the Canadian mining industry, including a metal-like element called selenium, are finding their way downstream into Montana and threatening fish populations there. John Bergenske, Executive Director of convservation group Wildsight, said,
"The science is clear: Selenium from the mines has polluted the river to levels known to be dangerous to fish. The selenium bio-accumulates and could lead to fish population collapse because it affects reproductive organs in fish. Eating them could also affect human health."
