MICROPLASTICS FOUND IN THE EASTERN OYSTER (Crassostrea virginica) AND THE SURROUNDING ENVIRONMENT
AI summary Read the abstract
Eastern oysters and surrounding water and sediment samples were collected from a US estuary and analyzed for microplastic content. Microplastics were found in both oysters and environmental matrices, though the oysters did not accumulate particles proportionally to environmental concentrations, suggesting selective ingestion. The study contributes to understanding how commercially important bivalves interact with microplastics in their natural habitat and what this means for seafood safety.
Prevalence of Microplastics in the Eastern Oyster Crassostrea virginica in the Chesapeake Bay: The Impact of Different Digestion Methods on Microplastic Properties
AI summary Read the abstract
Eastern oysters from three Chesapeake Bay sites were found to contain microplastics, with hydrogen peroxide and potassium hydroxide digestion methods yielding the highest recovery rates, while nitric acid produced satisfactory results with better microplastic preservation.

Researchers quantified microplastics in the tissues of eastern oysters and Atlantic mud crabs collected from South Carolina estuaries, documenting plastic types and abundances in these commercially and ecologically important species and contributing to understanding human dietary exposure from consuming shellfish.
Quantifying Spatial and Temporal Trends of Microplastic Pollution in Surface Water and in the Eastern Oyster Crassostrea virginica for a Dynamic Florida Estuary
AI summary Read the abstract
Researchers monitored microplastic pollution in surface waters and tissues of the eastern oyster Crassostrea virginica across 35 sites in Florida's Indian River Lagoon over one year using microscopy and ATR-FTIR, quantifying spatial and temporal variability in MP abundance and identifying factors influencing distribution patterns in this dynamic estuarine system.
The relationship between microplastics in eastern oysters (Crassostrea virginica) and surrounding environmental compartments in Long Island Sound
AI summary Read the abstract
This study measured microplastics in eastern oysters, water, marine snow, and sediment in Long Island Sound and found low overall concentrations, with sediment having the most plastic. Few polymer types were shared between oysters and the surrounding environment, suggesting oysters are not efficient indicators of local microplastic pollution despite being widely used as biomonitors. The results help refine what kinds of plastic particles reach seafood consumers versus what remains in the broader environment.
