Substance derived from tire debris is toxic to two trout species, not just coho salmon

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 U.S. West Coast. Now, researchers report that exposure to 6PPD-quinone at environmentally relevant levels can also be deadly for rainbow and brook trout, though not for Arctic char or white sturgeon.
