Researchers from the Scholes Lab at the University of British Columbia (UBC) worry that a newly identified tire toxicant is threatening coho salmon populations. They’re now working to determine which streams and rivers are most affected.
As part of the STREAM (Salmon Toxic Runoff Exposure and Mitigation) project, an inter-disciplinary group of researchers are developing a model to identify which streams and rivers are most vulnerable to the toxicant, known as 6PPD-quinone. In parallel with identification, the project works to design ways of removing the toxicant from stream runoff before it reaches salmon waters.
