Preliminary Research Sheds Light on Proper Analysis and Sample Handling for the Tire-Derived Contaminants 6PPD and 6PPD-quinone
Tire and road wear particles have been shown to cause acute effects to sensitive aquatic animals and degrade their habitats. U.S. Geological Survey (USGS) scientists developed methods to accurately identify aquatic compounds, such as 6PPD and 6PPD-quinone, that can cause acute mortality events in coho salmon (Oncorhynchus kisutch).

Green-Duwamish Watershed 6PPD-q small stream monitoring
Pacific salmon and trout, especially coho, are threatened by a toxic contaminant resulting from tire additives that end up in untreated road runoff. This contaminant, 6PPD-q, has been associated with high rates of coho pre-spawn mortality in streams, including in the Green-Duwamish watershed. Many coho spawning streams in the watershed are predicted to be at high risk for “urban runoff mortality...
