PSI Research: Modeling Contaminants through Food Webs

Main page content

There is concern about the level of toxic contaminants (such as PCBs, PBDEs, and PAHs) found in aquatic organisms throughout the Puget Sound food web, including groundfish, salmon, herring, and orcas. The Puget Sound Institute is partnering with scientists at NOAA's NWFSC and WDFW to model the flow of contaminants through the Puget Sound food web, to shed light on the potential pathways by which contaminants reach animals at higher trophic levels. These pathways will aid in the management of toxic contaminants entering Puget Sound.
