Summary
Description
Chinook salmon are critical species in the Puget Sound pelagic food web. Puget Sound Chinook are accumulating polybrominated diphenyl ethers (PBDEs), contaminants of emerging concern. However, information on tissue concentrations of PBDEs associated with adverse effects in salmon and other fish is limited. These data are critical for assessing the risk associated with current and future levels of PBDEs in threatened salmon stocks. We propose to expose salmon to levels of PBDE congeners found previously in Puget Sound Chinook, as well as encompass levels of uncertainties associated with model predictions and potential climate change. The output of this project will significantly contribute to increasing the scientific understanding of the impacts of PBDE exposure by developing dose-response data of disease susceptibility, and endocrine and immune function. An outcome of this study is the protection of Puget Sounds food web and waters by developing protective standards for aquatic life and reducing toxins.
