2023 - Present
Synthetic materials, many now broadly classified as plastics, are present in nearly every ecosystem on the planet and their breakdown products are an established threat to environmental health, affecting marine and freshwater organisms and ecosystems. Installation of home washing machine filters, which capture MFs before they enter gray water leaving facilities and homes, has been reported outside of the U.S. as a successful wastewater control measure2023, but the U.S. currently lacks the supporting data to facilitate regulation around and implementation of this control measure.
This transdisciplinary MP-SOS project would use hydrology, engineering, social science, and education methods to improve our understanding of the relative contributions of two sources of MP contamination from stormwater and wastewater in coastal watersheds; implement interventions to reduce these MP sources, pilot test a third intervention to an atmospheric MP source of deposition to waterways and assess difficulties for users of these interventions; and engage students, the interested public, and relevant professionals in awareness raising and drafting of strategies to scale up interventions based on project findings.
Bria Bleil's thesis focused on pesticide occurrence on the Oregon coast and its potential effects on the aggregating anemone. During the summer of 2024, in collaboration with the Apprenticeships in Science & Engineering (ASE) program, intern Annice Han documented this research to create a short film.
Thanks to Annice Han, NW Documentary, and ASE for making this happen!

Microplastics (MPs) have been identified as a leading emerging contaminant in marine and freshwater environments and a threat to organisms and ecosystems, amplifying concerns about effects on and contamination of seafood, particularly in edible tissues. A growing body of scientific literature has been generated on the abundance and effects of MPs - including growth, reproduction, and fitness effects on diverse marine species . Organismal effects suggest potential ecosystem level consequences ranging from decreased productivity of fisheries important to Oregon coastal communities to potential effects of MPs and their associated contaminants on human health. In light of these findings, MPs have been likened and linked to climate change as a global marine threat, particularly since plastic production is predicted to increase exponentially over the next several decades, yet we lack a comprehensive approach to reduce their entry into riverine, coastal, and marine ecosystems. For this chronic stressor in marine and freshwater environments, data gaps exist in the scientific understanding of microplastics' uptake in important fishery species, as well as potential solutions to address microplastics that consider social, cultural and political dimensions of the issue, and leverage tools from the social and political sciences and end user engagement to develop solutions that are protective of fisheries and responsive to stakeholder needs
Building upon previous findings, our transdisciplinary SEED project used ecotoxicology and political science methods to 1) improve our understanding of the extent and types of microplastics contamination with the highest relevance to human exposure in Oregon seafood by analyzing consumed tissues of 6 species (pink shrimp, Chinook salmon, Black rockfish, lingcod, herring, and lamprey), 2) identify current state of knowledge, issue prioritization, and tools available to address this growing stressor in both freshwater and marine species and ecosystems, and 3) connect with .environmental engineers working on technological solutions to microplastics delivery to waterways and coastal oceans.

Using field and lab approaches, these projects examine concentrations of pharmaceuticals in Oregon and Washington seawater and bivalve tissue, and effects of pharmaceuticals on marine organisms such as mussels, crabs, and oysters.

Implementing traditional bio-monitoring techniques as well as passive water sampling this project aims to understand if/how current forestry policy and practice in Oregon's Coast Range affects filter feeding bivalves in freshwater and estuarine systems downstream.
