    • Lower Duwamish River, Washington, sculpin growth study evaluating fish tissue, otoliths, and surrounding sediment for injury from chemical contaminant exposure data collected from 2018 to 2020 (NCEI Accession 0283629)

    Metadata Updated: August 1, 2025

    The Lower Duwamish River is a highly industrialized waterway flowing into the densely urbanized Puget Sound waterfront of Seattle, WA. As part of a Natural Resource Damage Assessment (NRDA) addressing historical pollution at three designated Superfund sites (i.e., the assessment area), the National Oceanic and Atmospheric Administration (NOAA) sampled juvenile Pacific staghorn sculpin (Leptocottus armatus) throughout the lower river in order to evaluate injury from exposure to pollutants including Polycyclic Aromatic Hydrocarbons (PAHs), Polychlorinated Biphenyls (PCBs), Dichlorodiphenyltrichloroethane (DDT), and Tributyltin (TBT). Sculpin live in close association with the river sediments within and upriver of the assessment area. Fish were collected for analysis of contaminant concentrations in composited whole bodies and stomach contents, as well as for individual fish health metrics including daily somatic growth rates measured from otoliths. Sediment contaminant concentrations were also measured at sites in close proximity to fishing locations.
