Rubber-derived contaminant monitoring in salmon bearing habitats, Washington State Department of Ecology

Conduct method development activities to verify the best methods for measuring rubber-derived contaminants transported to salmon bearing habitats. The contaminant 6PPD-quinone is acutely toxic to coho salmon, rainbow and brook trout. Targeted analysis will be implemented to further our understanding of the occurrence, persistence and exposure risk to vulnerable species and habitats. The sampling will involve, spatial sampling, a focused stream study and directed method development short-term, small-scale studies.
