Every time it rains, fish living downstream of storm drains are exposed to pollutants, including the tire-derived compound 6PPD-quinone, in the runoff. Recently, this substance has been linked to massive die-offs of coho salmon across the US West Coast. Now, researchers in Canada report that exposure to 6PPD-quinone at environmentally...
A chemical called 6PPD has been used in tires for decades to protect them from oxidation, essentially keeping the rubber from cracking and crumbling. But when exposed to oxygen and ozone in the environment, that tire protecting chemical transforms into another, called 6PPD-quinone, and that's what researchers in Washington found is highly toxic to the salmon.
