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.
