Factors influencing the microplastic contamination of bivalves from the French Atlantic coast: Location, season and/or mode of life?
AI summary Read the abstract
This study characterized microplastic contamination in blue mussels and Pacific oysters collected from the French Atlantic coast, examining how season, location, and organism size influence contamination levels. The findings provide a baseline for monitoring bivalve contamination and informing seafood safety assessments.
Monitoring the presence of microplastics (MP) in marine organisms is currently of high importance. This paper presents the qualitative and quantitative MP contamination of two bivalves from the French Atlantic coasts: the blue mussel (Mytilus edulis) and the Pacific oyster (Crassostrea gigas). Three factors potentially influencing the contamination were investigated by collecting at different sampling sites and different seasons, organisms both wild and cultivated. Inter- and intra-species comparisons were also achieved. MP quantity in organisms was evaluated at 0.61±0.56 and 2.1±1.7MP per individual respectively for mussels and oysters. Eight different polymers were identified. Most of the MPs were fragments; about a half of MPs were grey colored and a half with a size ranging from 50 to 100μm for both studied species. Some inter-specific differences were found but no evidence for sampling site, season or mode of life effect was highlighted.

Spatial Comparison and Characterization of Microplastic Contamination in Blue Mussels (Mytilus edulis) and Eastern Oysters (Crassostrea virginica) from Nova Scotia, Canada
AI summary Read the abstract
Researchers quantified microplastics in blue mussels and eastern oysters at 13 locations across Nova Scotia, Canada, finding average concentrations of roughly 4 particles per gram of tissue, with higher contamination near Halifax and aquaculture areas. Because mussels and oysters are widely consumed whole, these findings confirm meaningful human dietary microplastic exposure from commercially farmed and wild shellfish at concentrations associated with oxidative stress and metabolic disruption in laboratory studies.
