Investigation of microplastics in edible wild mussels from İzmir Bay (Aegean Sea, Western Turkey): A risk assessment for the consumers
Summary
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.
The presence of microplastics (MPs) was determined in Mediterranean mussel (Mytilus galloprovincialis Lamarck, 1819) and grooved carpet shell (Ruditapes decussatus Linnaeus, 1758) together with water samples from in İzmir Bay (Aegean Sea, Western Turkey). A total of 895 MPs from Karşıyaka (Station 1), and 787 MPs from Gülbahçe (Station 2) were detected in 60 mussel samples, giving a total content of 1682 MPs. In water samples, a total of 545 MPs were detected in samples from Station 1 and 1287 MPs in samples from Station 2 (1832 MPs total). The amount of MPs in water samples was less in Station 1 than in Station 2. This difference is probably caused by Çiğli Wastewater Treatment Plant (WWTP) located near Station 1. Public health risk assessment on the consumption of the species M. galloprovincialis revealed that 70.82 items person year MPs through this species could enter consumers' digestive systems.

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.
A Comprehensive Identification, Distribution and Health Risk Assessment of Microplastics in Natural Mussels from the Shoreline of the Sea of Marmara, Türkiye
Researchers collected 322 mussels from across the Sea of Marmara coastline in Turkey and found microplastic contamination in all samples, with fibers being the most common shape and polyethylene the dominant polymer. Locations near river mouths and areas under heavy human influence showed the highest contamination levels. Risk assessment calculations indicated that children face the greatest exposure through seafood consumption, with an estimated annual intake of 1,940 microplastic particles based on 100 grams of daily consumption.
Microplastic pollution profile of Mediterranean mussels (Mytilus galloprovincialis) collected along the Turkish coasts
Researchers analyzed microplastic pollution in Mediterranean mussels collected from 23 locations along Turkey's Black Sea, Sea of Marmara, and Aegean Sea coastlines. The study found widespread microplastic contamination in mussels across all sampling sites, highlighting their role as vectors for microplastic transfer to humans through seafood consumption.
A Hazard Index of Microplastics Contamination in Commercial Marine Fish Species and Mussels in the Southern Marmara Sea, Turkey
Researchers assessed microplastic contamination in five commercially important fish species and Mediterranean mussels from the southern Marmara Sea in Turkey. They found microplastics in all species examined, with varying levels of contamination across different collection sites, and calculated hazard indices to estimate potential risks. The study provides evidence that seafood consumers in the region may face meaningful dietary exposure to microplastics.
The microplastic pattern of wild-caught Mediterranean mussels from the Marmara Sea
Researchers surveyed wild Mediterranean mussels from 20 sites along the Sea of Marmara coastline for microplastic contamination. They found an average of about 2 microplastics per mussel, predominantly fibers and fragments in the smaller size ranges. The study highlights that microplastic pollution is widespread in this inland sea, raising concerns about seafood safety for consumers in the region.
