ClearExposure to low-density polyethylene microplastic particles: presence in Mytilus edulis tissues and pseudofeces
Researchers exposed blue mussels to low-density polyethylene microplastics at different concentrations for up to 56 days and found particles in gills, intestinal lumens, and digestive tissues. Mussels also expelled plastic particles in their pseudofeces, demonstrating both uptake and a partial clearance mechanism for microplastic exposure in filter feeders.
Selective Ingestion and Egestion of Plastic Particles by the Blue Mussel (Mytilus edulis) and Eastern Oyster (Crassostrea virginica): Implications for Using Bivalves as Bioindicators of Microplastic Pollution
Blue mussels and eastern oysters were found to selectively ingest and egest microplastic particles based on size and composition, with both species showing preferences that differed from random ingestion. The selective behavior affects how reliably these bivalves can be used as bioindicators of microplastic pollution, since their gut contents may not proportionally reflect ambient plastic concentrations.
Determining the Properties that Govern Selective Ingestion and Egestion of Microplastics by the Blue Mussel (Mytilus edulis) and Eastern Oyster (Crassostrea virginica)
Researchers examined how particle properties govern selective ingestion and egestion of microplastics by blue mussels and eastern oysters, finding that bivalves selectively process different microplastic types based on physicochemical characteristics and size.
An assessment of the ability to ingest and excrete microplastics by filter-feeders: A case study with the Mediterranean mussel
Mediterranean mussels (Mytilus galloprovincialis) were exposed to spherical polystyrene microplastics of different sizes and concentrations and examined for tissue-level effects and ingestion/egestion dynamics, with smaller particles showing greater retention and histological changes in digestive tissue. The study provides detailed pathophysiological evidence that MP size governs both retention time and the severity of tissue-level effects in marine filter feeders.
The fate of microplastics during uptake and depuration phases in a blue mussel exposure system
A controlled exposure system tracked the fate of polystyrene microplastic beads in blue mussels during uptake and depuration phases, showing that mussels accumulated beads in the digestive gland and that depuration cleared most but not all particles over 24 hours. The mass balance approach provides a rigorous method for quantifying microplastic retention in bivalves.
The Effect of Exposure to Microplastic Particles on Baltic Sea Blue Mussel (Mytilus edulis) Filtration Rate
Baltic Sea blue mussels were exposed to 1,000 microbeads per liter for six days, and the study found no significant difference in filtration rate compared to unexposed mussels. While this single concentration did not impair feeding, the study provides early baseline data on mussel responses to microplastic exposure.
Quantification and characterization of microplastics in blue mussels (Mytilus edulis): protocol setup and preliminary data on the contamination of the French Atlantic coast
Researchers quantified and characterized microplastics in blue mussels from a study site, finding microplastics in a large proportion of sampled individuals and documenting the types and sizes of particles present.
Insights into the uptake, elimination and accumulation of microplastics in mussel
Researchers investigated how mussels take up, eliminate, and accumulate high-density polyethylene microplastics smaller than 22 micrometers. They found that mussels cleared microplastics at the same rate as similarly sized food particles, but smaller particles (under 6 micrometers) were retained much longer in the digestive gland. After six days of depuration, about 85 percent of ingested microplastics were eliminated, but 2 to 6 percent remained embedded in digestive tissue, indicating that small microplastics can accumulate in filter-feeding organisms.
Effects of nanopolystyrene on the feeding behavior of the blue mussel (Mytilus edulis L.)
Researchers investigated how 30-nanometer polystyrene particles affect the feeding behavior of blue mussels. They found that exposure to nanoplastics caused mussels to produce pseudofeces, increase total waste output, and reduce filtering activity, indicating that nanoplastics disrupt normal feeding processes in these organisms.
Effects of long-term exposure to microfibers on ecosystem services provided by coastal mussels
Researchers examined the effects of long-term microfiber exposure on the biofiltration capacity of coastal mussels, investigating whether small microfibers (more common in nature than the larger microplastics studied previously) impair this important ecosystem service that helps mitigate coastal eutrophication.
Application of the Blue Mussel (Mytilus edulis) as an indicator of microplastic pollution within the Salish Sea
This study used blue mussels placed at 11 sites in British Columbia waters to measure microplastic pollution, finding an average of about 2 microplastic particles per mussel, with 91% being fibers. The results suggest mussels could serve as useful indicators of microplastic contamination in marine environments. Since mussels are also a food source for humans, these findings are relevant to understanding our dietary exposure to microplastics.
Size-Based Ingestion of Microspheres and Microfibers by Two Freshwater Mussel Species (Dreissena bugensis and Elliptio complanata): Implications for Removal of Microplastic Particles from Aquatic Systems
Researchers investigated size-based ingestion of microspheres and microfibers by two freshwater mussel species, the quagga mussel Dreissena bugensis and Elliptio complanata, to evaluate their potential for removing microplastics from aquatic systems. They found that ingestion and rejection patterns varied by particle shape and size, with implications for using suspension-feeding bivalves as natural microplastic filters.
Uptake and Effects of Microplastics on Cells and Tissue of the Blue Mussel Mytilus edulis L. after an Experimental Exposure
Researchers exposed blue mussels to high-density polyethylene microplastics and found the particles were drawn into the gills and digestive system within just three hours. The microplastics triggered a strong inflammatory response and damaged cell membranes, providing direct evidence that microplastics can enter animal cells and cause significant tissue-level harm.
Ingestion of nano/micro plastic particles by the mussel Mytilus coruscus is size dependent
Researchers investigated how the thick shell mussel Mytilus coruscus ingests plastic particles of different sizes, ranging from 70 nanometers to 100 micrometers. They found that smaller particles were ingested in greater quantities and accumulated primarily in the digestive tract, while particles also translocated to the mantle tissue over time. The study demonstrates that plastic particle ingestion by mussels is strongly size-dependent, with smaller particles posing a greater accumulation risk.
Microplastic changes the sinking and resuspension rates of marine mussel biodeposits
Researchers found that microplastic exposure altered the sinking rates and resuspension velocities of mussel biodeposits, demonstrating that microplastics can disrupt benthic-pelagic coupling by changing the physical properties of marine mussel fecal pellets and pseudofeces.
Capturing marine microplastics with mussel power
Researchers scaled up the use of Mytilus edulis (blue mussel) cage systems to capture and sequester microplastics from coastal marine environments, testing 50 kg mussel cage systems with feces collection and pump-based sample retrieval at ecologically relevant locations. Building on laboratory results showing mussels could filter 200,000 microplastics per hour, the study assessed the feasibility of mussel-based biofiltering as a passive environmental remediation strategy.
Depuration kinetics and accumulation of microplastics in tissues of mussel Mytilus galloprovincialis
This study tracked how mussels take in, accumulate, and eventually expel microplastics of different sizes over time. Larger microplastics accumulated more in the gills and digestive gland, while smaller particles spread more widely through the body. Since mussels are popular seafood eaten whole, understanding how they retain microplastics helps estimate how much plastic people may be consuming through shellfish.
Morphological analysis approach to detect microfiber contamination in Mytilus galloprovincialis
Researchers investigated microfiber contamination in Mediterranean mussels (Mytilus galloprovincialis) using morphological analysis, finding microplastic presence in 65% of analyzed specimens and demonstrating that mussels serve as effective bioindicators for assessing environmental microplastic exposure.
Particle characteristics of microplastics contaminating the mussel Mytilus edulis and their surrounding environments
Researchers investigated microplastic uptake into mussels (Mytilus edulis) and their surrounding sediment and seawater at nine intertidal sites in southwest England, characterizing particle abundance, size, shape, and polymer composition across environmental compartments and mussel tissue.
Effect of seasonal changes in temperature on capture efficiency in the blue mussel, Mytilus edulis, fed seston and microplastics
Year-round experiments with blue mussels showed that their efficiency at capturing suspended particles from ambient seawater — including microplastics — changes with the seasons, likely due to temperature-driven shifts in water viscosity and mussel physiology. Because mussels are a major filter feeder in coastal ecosystems and a widely eaten seafood, understanding when they most readily take up microplastics matters for both ecology and food safety.
Use of the Mediterranean mussel (Mytilus galloprovincialis) filtration function as a sustainable tool for water column microplastic monitoring
Researchers investigated using Mediterranean mussels (Mytilus galloprovincialis) as living samplers to monitor microplastic levels in seawater, taking advantage of the mussels' natural filter-feeding behavior to concentrate particles from the surrounding water column. This biological monitoring approach could provide a cost-effective and ecologically relevant tool for tracking microplastic pollution.
Bivalves as Biological Sieves: Bioreactivity Pathways of Microplastics and Nanoplastics
This review examines how filter-feeding bivalves like mussels and oysters process and accumulate microplastics and nanoplastics of different sizes. Researchers found that larger particles pass through relatively quickly in feces, while smaller microplastics and nanoplastics tend to accumulate in digestive tissues and immune cells with longer retention times, making bivalves valuable bioindicators of plastic pollution.
Quantifying spatial variation in the uptake of microplastic by mussels using biodeposit traps: A field-based study
Researchers used novel biodeposit traps to measure how mussels in different field locations take up and excrete microplastics, finding significant spatial variation in uptake rates. Mussels can serve as natural biomonitors of local microplastic contamination, with their biodeposits revealing how much plastic is present in their environment.
Histopathological and cytochemical analysis of ingested polyethylenepowder in the digestive gland of the blue mussel, Mytilus edulis (L.)
Researchers examined the damage caused by ingested polyethylene powder in the digestive glands of blue mussels using microscopy and chemical staining, providing histological evidence of cellular effects. The study demonstrated that physical ingestion of plastic particles causes measurable tissue-level harm in the digestive organs of these widely consumed shellfish.
