Microplastic Concentrations in Crassotrea gigas : Establishing a Baseline of Microplastic Contamination in Oregon's Oyster Aquacultures
Anthropogenic debris is “found across all habitats in the ocean, including coral reefs, shallow bays, estuaries, the open ocean, and the deep sea” (Rochman et al., 2015). Microplastic pollution is widespread in the marine environment and poses a threat to a variety of organisms, including commercial...

Anthropogenic debris is “found across all habitats in the ocean, including coral reefs, shallow bays, estuaries, the open ocean, and the deep sea” (Rochman et al., 2015). Microplastic pollution is widespread in the marine environment and poses a threat to a variety of organisms, including commercial shellfish grown for human consumption. The aim of this study is to establish a baseline of microplastic evidence in Oregon through the examination of Crassotrea gigas--or the Pacific Oyster. In addition it hopes to determine if there are differences in microplastic concentration geographically and temporally. Five oyster samples were collected in Spring 2017 from a total of six sites, three Northern and three Southern to establish a geographic range of XXXX Pacific oyster aquacultures.
