ClearMicroplastics in Marine and Estuarine Species From the Coast of Portugal
Researchers surveyed microplastic contamination in five marine and estuarine species collected from the coast of Portugal, including mussels, clams, and polychaetes. They found microplastics in all species examined, with fibers being the most common type, and noted differences in contamination levels between sampling sites. The study contributes baseline data on microplastic pollution in commercially relevant Portuguese seafood species.

Microplastic contamination in marine mussels from the Atlantic coast of North Portugal and human risk of microplastic intake through mussel consumption
Researchers analyzed wild mussels from Portugal's Atlantic coast and found microplastics in all samples, with an average of about 1.6 particles per gram of mussel tissue. Based on typical Portuguese seafood consumption patterns, the estimated annual human intake of microplastics from mussels alone was calculated, highlighting that regular shellfish consumers face meaningful microplastic exposure through their diet.

Researchers developed a versatile analytical approach to evaluate the occurrence of microfibers in mussels (Mytilus galloprovincialis) collected from the Tyrrhenian Sea, finding fibrous microplastics to be the most abundant form of micro-debris in both the environment and the bivalves sampled.
ASSESSMENT OF THE BIOACCUMULATION OF MICROPLASTICS IN THE BLACK SEA MUSSEL Mytilus galloprovincialis L., 1819
Researchers examined microplastic accumulation in the Black Sea mussel Mytilus galloprovincialis collected from multiple sites along the Bulgarian coast. Microplastics were detected in all samples with fragment and fiber morphologies dominant, and differences in abundance were observed between sampling locations linked to proximity to human activities.
Mytilus spp. as sentinels for monitoring microplastic pollution in Norwegian coastal waters: A qualitative and quantitative study
Researchers collected mussels from 15 sites along Norway's coastline and found microplastics at nearly every location, with remote Arctic sites containing surprisingly high levels — often more than sites near major cities. The study confirms that mussels are useful sentinels for monitoring microplastic pollution in coastal waters, with fibers making up 83% of all particles found.
First occurrence and composition assessment of microplastics in native mussels collected from coastal and offshore areas of the northern and central Adriatic Sea
Microplastics were detected for the first time in native mussels from coastal and offshore areas of the northern and central Adriatic Sea, with chemical analysis confirming common plastic polymers and offshore populations also affected. The study establishes a baseline for microplastic contamination in an important Mediterranean commercial shellfish species.
A versatile approach to evaluate the occurrence of microfibers in mussels Mytilus galloprovincialis
Researchers developed a versatile morphological approach to discriminate natural from synthetic microfibers in farmed mussels, enabling more accurate assessment of microplastic contamination in commercial shellfish relevant to human food safety.
Microplastics in Mollusks: Research Progress, Current Contamination Status, Analysis Approaches, and Future Perspectives
This review synthesizes 77 studies (2010-2021) on microplastic contamination in mollusks, finding that polypropylene, polystyrene, and polyethylene are the most common polymers in bivalves, with most particles under 500 µm in size and a positive correlation between seawater and mollusk MP abundance.
Comparative analysis of microplastic pollution in commercially relevant seafood across different geographical regions
This study compared microplastic contamination across commercially relevant seafood species commonly consumed in the European market, characterizing both the morphological and chemical properties of particles found in edible tissue. Results showed widespread but variable contamination across species, with polymer types and particle abundance differing by species and tissue type.
Microplastics in mussels along the coastal waters of China
Researchers surveyed microplastic contamination in mussels collected from coastal waters spanning the entire coastline of China. They found microplastics in all samples, with fibers being the dominant type and concentrations varying by region. The study provides the first large-scale baseline data on microplastic pollution in Chinese coastal bivalves, highlighting areas of particular concern and confirming that filter-feeding shellfish are reliable indicators of local microplastic contamination.
Binational survey using Mytilus galloprovincialis as a bioindicator of microplastic pollution: Insights into chemical analysis and potential risk on humans
Researchers conducted surveys of microplastic contamination in mussels from coastal sites across Morocco and Tunisia, finding plastics in 79 to 100 percent of all samples. The most common types were polyethylene and polypropylene fibers and fragments, with chemical analysis revealing the presence of associated toxic additives. The study estimates that regular mussel consumers in these regions face meaningful microplastic intake, highlighting a potential human health concern.
Microfibers in Mytilus species(Mollusca, Bivalvia)from Southern California Harbors, Beaches, and Supermarkets
This study found microplastic fibers in both wild and farmed mussels from Southern California harbors, beaches, and supermarkets, with fibers present in the majority of samples. The presence of microfibers in commercially sold mussels confirms that these filter feeders are a direct route for human consumption of microplastics through everyday seafood.
Abundance, composition, and distribution of microplastics in intertidal sediment and soft tissues of four species of Bivalvia from Southeast Brazilian urban beaches
