Edible Seaweeds Of The Salish Sea: Contaminant Levels And Comparison With Common Foods, Jennifer Hahn
Edible Seaweeds Of The Salish Sea: Contaminant Levels And Comparison With Common Foods, Jennifer Hahn
WWU Graduate School Collection
To increase our seafood safety knowledge with respect to seaweed, this study compares contaminant concentrations in three species of edible seaweeds (Fucus distichus, F. spiralis, and Nereocystis luetkeana) harvested from 43 locations within the Salish Sea from June to September 2015. Fucus spp. were analyzed for 162 chemicals: 17 metals, 94 persistent organic pollutants (POPs) and 51 polycyclic aromatic hydrocarbons (PAHs). Nereocystis luetkeana was analyzed for metal content. Two health-based screening levels were calculated, one on the U.S. Environmental Protection Agency (USEPA) Reference Dose (RfD) and the other on the USEPA Cancer Slope Factor (CSF) when these data …

Metrics Of Shoreline Armoring Impacts On Beach Morphology In The Salish Sea, Wa, Hannah Drummond

Coastal development, and the shoreline defenses that accompany it, makes it important to understand the shoreline’s response to anthropogenic modifications. Armoring, or shoreline erosion control structures such as seawalls or riprap, is found on an estimated one third of Salish Sea shorelines and has been shown to degrade nearshore habitat. We compared physical beach characteristics from adjacent sections of armored and unarmored shoreline at locations throughout the Salish Sea to assess the effects of armoring on beach morphology. Nineteen sites, each approximately 500 meters alongshore, were selected from ten reaches sampled with boat-based LiDAR by the WA Dept. of Ecology …
