Microplastic concentrations in two Oregon bivalve species: Spatial, temporal, and species variability
Abstract Microplastics are an ecological stressor with implications for ecosystem and human health when present in seafood. We quantified microplastic types, concentrations, anatomical burdens, geographic distribution, and temporal differences in Pacific oysters (Crassostrea gigas) and Pacific razor...

Microplastics were present in organisms from all sites.
