Microplastic pollution in wild and aquacultured Mediterranean mussels from the Sea of Marmara: Abundance, characteristics, and health risk estimations
Researchers compared microplastic contamination in wild and commercially farmed mussels from the Sea of Marmara in Turkey. They found microplastics in all mussel samples, with wild mussels containing somewhat different types and amounts compared to aquacultured ones, and fibers being the dominant form in both. The study estimates that regular consumption of these mussels represents a measurable pathway for human exposure to microplastics through seafood.
Microplastics in European sea salts – An example of exposure through consumer choice and of interstudy methodological discrepancies
Researchers analyzed 13 European sea salts and found microplastics in all of them, with industrially harvested salts containing more particles than traditionally harvested ones. They estimated that a person absorbs about 14 micrograms of microplastics annually from all salt consumption, with a quarter attributable to choosing sea salt specifically. The study also found that differences in research methods across studies make it difficult to compare microplastic levels in salt worldwide.
Microplastics in fillets of Mediterranean seafood. A risk assessment study
Researchers analyzed fillets of several common Mediterranean seafood species for microplastic contamination and estimated the associated human dietary exposure. They detected microplastics in the edible tissue of all species tested, including sardines, sea bream, and mussels. The study provides risk estimates suggesting that regular seafood consumption represents a notable pathway for human microplastic ingestion.
Microplastics in mussels sampled from coastal waters and supermarkets in the United Kingdom
Researchers measured microplastic contamination in mussels from U.K. coastal waters and supermarkets and found anthropogenic debris in every sample tested. Wild mussels contained up to 2.9 debris items per gram of tissue, while supermarket mussels showed lower but still consistent contamination levels. The study confirms that microplastics are prevalent in commercially available shellfish, representing a direct pathway for human dietary exposure.
Microplastic contents from maricultured and natural mussels
Researchers compared microplastic content in maricultured and wild mussels from Italian waters and found no significant difference between the two sources, with all recovered particles being filaments. The study estimates that consuming raw mussels could result in a median intake of 6 to 7 microplastic items per gram, highlighting a consistent route of human dietary exposure regardless of whether mussels are farmed or wild-caught.
The Global Spread of Microplastics: Contamination in Mussels, Clams, and Crustaceans from World Markets
Researchers used a standardized method to analyze microplastic contamination in commercially sold clams, mussels, and crustacean shellfish from markets in Belgium, Croatia, Serbia, and South Korea. Microplastics were found in about 44% of the 190 samples, with less than one particle per individual on average, and crustacean shellfish had the lowest contamination per gram of edible tissue. The type of shellfish was a stronger predictor of contamination levels than geographic origin, and the data did not support bioaccumulation with animal size.
Risk assessment of microplastic in commercial salt sold in Malaysia
Researchers conducted a risk assessment of microplastics in commercial table salt sold in Malaysia, finding that contaminated seawater used during sea salt production introduces microplastics into a widely consumed daily food ingredient with potential adverse health effects.

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.
Quantifying ecological risks of aquatic micro- and nanoplastic
This study analyzed microplastic contamination in table salts from multiple countries and found plastic particles present in the vast majority of samples tested. Sea salt contained the highest levels of microplastics compared to rock and lake salts, reflecting the extent of marine plastic pollution. The findings suggest that table salt is a previously underappreciated pathway for human microplastic ingestion, with estimated annual intake varying by geographic region.
Investigation of microplastics in edible wild mussels from İzmir Bay (Aegean Sea, Western Turkey): A risk assessment for the consumers
Researchers assessed microplastic contamination in edible wild mussels and water samples from two stations in Izmir Bay, Turkey. They detected over 1,600 microplastic particles across 60 mussel samples and nearly 1,900 particles in water samples, with fibers being the dominant type. The study included a public health risk assessment suggesting that regular consumption of these mussels results in meaningful microplastic intake for consumers.
Microplastic contamination in Indonesian consumable salts
Researchers analyzed both traditionally produced and commercial branded sea salts from Indonesia and found microplastics in all samples tested. Traditionally produced salts contained the highest contamination levels, with up to 3,753 particles per kilogram, though branded salts also contained significant amounts. The study indicates that sea salt is a notable dietary source of microplastic exposure for consumers.
Micro and Nanoplastics size distribution in mussel tissues: first evidence, identification, and quantification in the nanogram range
Italian researchers used a highly sensitive mass spectrometry technique to detect and quantify both microplastics and nanoplastics in farmed mussels, finding plastic particles in every sample tested. Nanoplastics in the 20–200 nm range were present in substantial quantities, and the authors estimate that European seafood consumers could ingest over 2 milligrams of nanoplastics per year through mussel consumption alone. This is one of the first studies to directly quantify nanoplastics in a commonly eaten seafood, raising significant concerns about dietary exposure.
Low levels of microplastics (MP) in wild mussels indicate that MP ingestion by humans is minimal compared to exposure via household fibres fallout during a meal
Researchers measured microplastic levels in wild mussels collected around the Scottish coast and found relatively low contamination compared to other studies. They then compared this to the amount of household dust fibers that settle onto a dinner plate during a typical meal and found that airborne fiber exposure during eating likely exceeds the microplastics ingested from a serving of mussels. The study suggests that for most people, indoor dust may be a more significant source of microplastic exposure than seafood consumption.
