Presentation Abstract
In the U.S. Pacific Northwest, coho salmon, (Oncorhynchus kisutch), annually exhibit acute mortality upon stormwater exposure when adult salmon migrate to urban and near urban creeks to reproduce. We recently linked these mortality events to “6PPD-quinone”, a highly toxic transformation product of a common industrial antioxidant chemical 6PPD that is ubiquitously used in vehicle tires. These results reveal unanticipated risks of tire rubber antioxidants to an important aquatic species and imply toxicological relevance for widely dissipated tire rubber residues. Management of roadway runoff in general, and 6PPD/6PPD-quinone specifically, will be a clear priority for maintenance of ecosystem health and function, especially for sensitive salmonids. This presentation will provide recent research updates on the environmental occurrence and fate characteristics of 6PPD-quinone and related compounds in roadway runoff and urban receiving waters.
