ClearSimple detection of polystyrene nanoparticles and effects in freshwater mussels: method development and in situ application to urban pollution
Researchers developed simple, low-cost tests to detect nanoplastics in freshwater mussels using a gold nanoparticle sensor, and found that nanoplastics reduced protein stability markers in mussel tissue. Mussels caged at sites downstream of urban runoff had the highest nanoplastic loads, demonstrating that accessible biological assays can track real-world contamination and its biochemical effects in aquatic wildlife.

Mussels and surrounding water near two wastewater treatment plant outfalls in Europe were monitored for microplastic contamination, finding that WWTP discharges elevated both environmental concentrations and mussel body burdens.
Spatial patterns of microplastics in freshwater bivalves (Bivalvia: Unionidae and Sphaeriidae) relative to municipal wastewater effluent discharges
Microplastics were found in freshwater bivalves (fingernail clams and mussels) collected along 155 km of Ontario's Grand River, with significantly higher concentrations downstream of municipal wastewater treatment plant discharges, confirming WWTPs as key sources of microplastic contamination in filter-feeding freshwater organisms.
Plastic pollution and marine mussels: Unravelling disparities in research efforts, biological effects and influences of global warming
This review analyzed 106 studies on how plastic pollution, including microplastics, nanoplastics, and chemicals that leach from plastics, affects marine mussels. The research found effects at every biological level, from molecular and cellular damage to changes in behavior and reproduction. Since mussels are filter feeders that concentrate pollutants and are widely eaten by humans, they serve as both early warning indicators of plastic pollution and a direct pathway for human exposure.
Microplastics, Additives, and Plasticizers in Freshwater Bivalves: Preliminary Research of Biomonitoring
Freshwater mussels (Anodonta cygnea) deployed in three Italian rivers accumulated microplastics primarily in their gills and digestive tracts, with polyamide (nylon) fibers being the most common type found. The study also detected plasticizers and additives within the bivalves, demonstrating that these organisms can serve as effective sentinels for monitoring the full chemical footprint of plastic pollution in river systems.
Microplastic in bivalves of an urbanized Brazilian estuary: Human modification, population density and vegetation influence
Researchers measured microplastic contamination in oysters, clams, and mussels from a heavily urbanized estuary in Brazil, finding that industrial and port activities were stronger predictors of contamination than population density. Clams accumulated the most microplastics, and the study highlights how shellfish from polluted coastal areas can serve as indicators of the microplastic levels humans may be exposed to through seafood.
In vivo bioaccumulation and responses of hemocytes of mussels Perna viridis to microplastics and nanoplastics exposure
Researchers found that mussels exposed to environmentally realistic levels of micro- and nanoplastics quickly accumulated the particles in their blood cells (hemocytes) at concentrations approaching those of the surrounding water. The smaller nanoplastics were more readily taken up and caused more damage to cellular structures called lysosomes. Since mussels are widely consumed as seafood, their ability to concentrate microplastics in their tissues is relevant to human dietary exposure.
Impact of Microplastic in Mexican Coastal Areas Using Mussels ( Mytilus spp.) as Biomonitors
This study used mussels as bioindicators to assess microplastic contamination along the Mexican Pacific coast, finding higher levels of microplastics and associated heavy metals in more urbanized areas. The results suggest potential health risks for people consuming seafood from contaminated coastal areas.
Bioaccumulation of emerging contaminants in mussel (Mytilus galloprovincialis): Influence of microplastics
Researchers investigated whether microplastics influence the bioaccumulation of emerging contaminants in Mediterranean mussels. The study found that the presence of microplastics altered how certain chemical pollutants accumulated in mussel tissue, suggesting that microplastics can act as carriers that change the uptake and distribution of other contaminants in marine organisms.
Assessment of the impact of aquaculture facilities on transplanted mussels (Mytilus galloprovincialis): Integrating plasticizers and physiological analyses as a biomonitoring strategy
Researchers assessed microplastic impacts on mussels transplanted near aquaculture facilities by integrating plasticizer analysis with physiological biomarkers, finding that proximity to aquaculture infrastructure increased both particle ingestion and chemical plasticizer exposure.
Physiological effects of plastic particles on mussels are mediated by food presence
Thick shell mussels exposed to polystyrene nanoplastics (70 nm) and microplastics (10 µm) with and without microalgae food found that food presence mediated the physiological effects — microplastics reduced energy budget and increased oxidative stress markers most strongly when food was mixed with particles.
Mikroplastens intåg i den limnologiska miljön - Allmän dammussla (Anodonta anatina) innehåller mikroplast
This Swedish study exposed freshwater mussels (Anodonta anatina) to microplastics and examined uptake and potential health effects, finding that mussels ingest microplastics and that higher exposures affected their physiology. The study contributes to understanding microplastic impacts on freshwater bivalves that are important for ecosystem function and serve as indicators of water quality.
Microplastic ingestion in mussels from the East Mediterranean Sea: Exploring its impacts in nature and controlled conditions
Mussels from fish farms in the eastern Mediterranean had the highest microplastic contamination, likely from plastic aquaculture equipment, while mussels from a Marine Protected Area had the lowest. The study found that higher microplastic levels in mussels were linked to measurable signs of oxidative stress, DNA damage, and nerve toxicity, showing that these filter-feeding shellfish -- commonly eaten by people -- are actively harmed by the plastic particles they ingest.
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.
Microplastic contamination in an urban area: a case study in Greater Paris
Researchers investigated microplastic contamination across Greater Paris, finding that urban areas generate and accumulate substantial microplastic pollution through multiple pathways including stormwater, atmospheric deposition, and river transport.
Plastic and natural inorganic microparticles do not differ in their effects on adult mussels (Mytilidae) from different geographic regions
Researchers compared the effects of plastic microparticles and natural inorganic particles on mussels from five geographic regions, finding no significant differences between particle types, suggesting that physical particle stress rather than plastic-specific chemistry drives observed effects.
Effect of size continuum from nanoplastics to microplastics on marine mussel Mytilus edulis: Comparison in vitro/in vivo exposure scenarios
Researchers compared the effects of nanoplastics versus microplastics on marine mussels using both in vivo and in vitro approaches, finding that smaller plastic particles caused greater cellular and physiological impacts across the size continuum.
Influence of Microplastics on Freshwater Bivalves (Review)
This review analyzed studies on microplastic uptake, bioaccumulation, and biological effects in freshwater bivalves, which serve as both pollution sentinels and vectors for microplastic entry into food webs. The authors found consistent evidence for particle accumulation causing physiological stress, while calling for more standardized exposure protocols to improve cross-study comparability.
Anthropogenic Litter in Urban Freshwater Ecosystems: Distribution and Microbial Interactions
Researchers quantified anthropogenic litter in urban rivers and streams and found that microplastics dominated by mass and particle count compared to macroplastic items. The study highlights urban freshwater systems as major conduits for plastic pollution moving toward marine environments and documents distinct microbial communities on plastic surfaces.

Microplastic Pollution in Green Shells in Aquatic Ecosystems: A Literature Review of Determinant Factors and Management
This literature review synthesized 35 studies on microplastic contamination in green mussels (a widely consumed shellfish), finding that fibers under 1 mm were the most common form and that both human and industrial activities drive contamination levels. Because mussels filter large volumes of water, they concentrate microplastics from their surroundings and pass them on to people who eat them, making shellfish a key pathway for human dietary exposure.
Microplastics in Invasive Freshwater Mussels (Dreissena sp.): Spatiotemporal Variation and Occurrence With Chemical Contaminants
Researchers measured microplastic ingestion by invasive zebra and quagga mussels (Dreissena spp.) across Great Lakes sites and time points, finding widespread MP uptake that varied by season and location and noting a weak but positive association between microplastic and chemical contaminant co-occurrence.
