Microplastics in Wild and Caged Mussels in Scotland, UK, and in Household Dust Downfall During a Meal (Edinburgh, UK)

AI summary Read the abstract

Microplastics were found in both wild and caged mussels in Scotland and in household dust collected during meal preparation in Edinburgh, providing data on environmental microplastic levels and potential human dietary exposure. Caged mussels deployed in an urbanized estuary showed seasonal variation in microplastic burden, suggesting dynamic environmental inputs.

Our data consists on microplastics (MPs) observations in mussel species in Scotland (UK) and from downfall dust on households in Edinburgh (UK) during the preparation of a meal. We deployed caged mussels (Mytilus edulis) in an urbanised estuary (Edinburgh, UK) to assess seasonal changes in plastic pollution, and collected mussels (Mytilus spp and subtidal Modiolus modiolus) from eight sampling stations around Scotland to enumerate MP types at different locations. MPs were extracted and quantified according to Catarino et al. (2017). Procedural blanks were used in every processing event, and data is also presented. We quantified to household dust fibres during a meal, using stationary passive samplers.

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

AI summary Read the abstract

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.

Microplastics in mussels sampled from coastal waters and supermarkets in the United Kingdom

AI summary Read the abstract

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.

Microplastics in seafood: Relative input of Mytilus galloprovincialis and table salt in mussel dishes

AI summary Read the abstract

Researchers quantified microplastics in mussels and table salt used in popular dishes from the Bay of Biscay, Spain. They found that mussels contained significantly more microplastics (0.55-3.20 items per gram) than table salt (0.1-0.38 items per gram), with levels correlating to environmental pollution at the harvesting site. The study suggests that consumers' risk of microplastic ingestion through seafood depends heavily on where the shellfish were collected, and recommends routine microplastic monitoring and labeling for seafood.

Are British Columbia blue mussels ingesting and retaining microplastics

AI summary Read the abstract

Blue mussels were deployed at 11 sites across the Strait of Georgia, British Columbia and monitored for microplastic ingestion over 60 days, providing the first microplastic data for mussels in this region. The results document widespread microplastic uptake by mussels across sites with varying levels of human activity.

Microplastic pollution in wild and aquacultured Mediterranean mussels from the Sea of Marmara: Abundance, characteristics, and health risk estimations

AI summary Read the abstract

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.
