Abstract
Puget Sound is as a hot spot of Persistent Bioaccumulative and Toxic (PBT) contaminants in northeastern Pacific waters, as illustrated by the levels of contaminants in its living organisms. Legacy contaminants such as polychlorinated biphenyls (PCBs) in Puget Sound herring are roughly 15 times higher than their oceanic coastal counterparts. Higher up the food chain, Chinook salmon of Puget Sound origin contain 3 to 5 times higher levels of PCBs than Chinook originating from Pacific coastal estuaries, and southern resident killer whales, primary predators of Chinook salmon, are considered one of the most PBT-contaminated species on the planet. In this talk, we explore the role of PBT biomagnification in the Puget Sound pelagic food web. We compare PBTs in the pelagic food web with benthic organisms, and observe how more recently emerged PBTs such as flame retardants behave in the Puget Sound ecosystem, in comparison to the older legacy PBTs like PCBs that have been in the system for over 40 years.
