Examination Of Microplastics And Organic Contaminants In Tampa Bay’S Eastern Oyster (Crassostrea Virginica) Through Visual And Chemical Analysis, Andrea Murray
USF Tampa Graduate Theses and Dissertations
Microplastic pollution is an increasingly alarming concern with widespread global distribution in aquatic environments. Filter feeding organisms such as bivalves, have a heightened risk of microplastic ingestion through free floating particulates in the water. This can lead to bioaccumulation moving up through trophic levels to apex predators and humans. Spatial and temporal differences in microplastic abundance were evaluated in the Eastern Oyster, Crassostrea virginica, at six sites within Tampa Bay. Oyster tissue was digested using 30% hydrogen peroxide (H2O2) and microplastics were quantified using Nile Red dye and fluorescent particle excitement. A total of 3025 microplastics were found throughout six …
