When a driver hits the brakes, friction releases copper shavings that fall onto the road and are eventually washed into rivers, where environmentalists say the metal could pose a hazard to marine life — especially salmon, one of the Pacific Northwest's most prized products.
"In 2008, Mexican authorities turned away an American shipment of beef, because it did not meet Mexico's limits when tested for copper traces. But the very same rejected meat could be sold in the United States, since no limit has been set, the analysis says."
There's far more copper(oxide) being released into the water from the anti fouling bottom paint on the boats parked at the local marina. Taking issue with copper in brake pads seems a bit....well, goofy.
Copper is bad for fish? I know copper is used in medication to treat ill fish... but I also know that copper is toxic to water invertebrates such as shellfish, clams, etc... So I wonder why copper is toxic to fish... or do they mean the marine invertebrates...
