Presentation Abstract
In a collaboration with the National Centers for Coastal Ocean Science (NCCOS) Mussel Watch Program (MWP), the Washington Department of Fish and Wildlife’s (WDFW) Mussel Monitoring program conducted a survey to assess the occurrence and distribution of contaminants of emerging concern (CEC) in Puget Sound nearshore biota. In the winter of 2019/2020, caged bay mussels (Mytilus trossulus) were deployed to forty sites along the Puget Sound nearshore, with sampling locations representing a wide range of potential COC exposures. After a three-month exposure period, a comprehensive CEC analysis targeting over 330 chemicals was performed on mussel tissue composite samples. CEC classes evaluated included pharmaceuticals and personal care products (PPCPs), alkylphenols, current-use pesticides, and perfluorinated compounds. A prior study using the same WDFW Mussel Monitoring program provided an initial assessment of the occurrence of CECs in the Puget Sound nearshore (18 sites) and demonstrated that nearshore biota exhibit a wide range of exposures to a suite of contaminants from multiple contaminant classes. We compare results from this expanded 2019/2020 survey and examine relationships to land-use types and proximity to putative point sources.

Occurrence and distribution of contaminants of emerging concern in the Puget Sound nearshore using a marine mussel monitoring program
