ClearImpacts of size-fractionation on toxicity of marine microplastics: Enhanced integrated biomarker assessment in the tropical mussels, Perna viridis
Researchers studied how different sizes of polystyrene microplastics (0.5, 5, and 50 micrometers) affect toxicity in tropical green mussels. The study found that smaller microplastics caused greater bioaccumulation and more severe toxic effects, including oxidative stress and tissue damage, indicating that size is a critical factor in determining microplastic toxicity in marine organisms.
Size-dependent effects of microplastics on intestinal microbiome for Perna viridis
Researchers found that the size of microplastic particles determines how they change the gut bacteria of green mussels, with the smallest particles causing the most disruption to beneficial bacteria and promoting potentially harmful species. Since mussels are widely consumed as seafood, changes to their gut health and the bacteria they carry could affect human food safety.

Researchers found microplastics in cultured green mussels (Perna viridis) from Sorsogon Bay, Philippines, ranging from 0.31 to 2.57 items per individual, with smaller-sized mussels showing the highest MP loads and organosiloxane and polyethylene terephthalate as the dominant polymer types.
Effect of microplastics and natural microparticles on green Mussel (Perna viridis)
Researchers compared the effects of microplastics and natural microparticles on green mussels (Perna viridis), finding that natural microparticles caused similar or greater stress responses, suggesting that studies using only microplastics may overestimate their specific contribution to marine organism harm.
Evaluation of microplastic bioaccumulation capacity of mussel (Perna viridis) and surrounding environment in the North coast of Vietnam
Researchers measured microplastic contamination in green mussels, seawater, and beach sediment along the northern coast of Vietnam. Mussels contained an average of about 25 microplastic pieces per individual, while beach sediments had concentrations around 4,800 pieces per kilogram. PET was the most common polymer type, and the study shows that Vietnamese coastal waters and seafood carry meaningful levels of microplastic contamination.
Heavy Metals Bioaccumulation in Different Sizes of the Green Mussel (Perna viridis) from Ujungpangkah Waters, Gresik, Indonesia
Researchers measured heavy metal accumulation in green mussels of different sizes from coastal waters near industrial areas in Gresik, Indonesia. As filter-feeding organisms, these mussels serve as bioindicators of water quality, and their ability to concentrate contaminants is relevant to understanding how pollutants including microplastics move through marine food webs. The study assessed whether mussel size affects contaminant accumulation levels in an area impacted by industrial activity.
Qualitative Assessment and Management of Microplastics in Asian Green Mussels (Perna viridis) Cultured in Bacoor Bay,Cavite, Phillipines
Green mussels cultured in Bacoor Bay in the Philippines were found to contain microplastics, which can accumulate persistent organic pollutants in the tissues of filter-feeding shellfish. Since green mussels are widely consumed as food, the findings raise food safety concerns about the combined exposure to microplastics and associated chemical contaminants.
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.
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.
Efficiency assessment of microplastic extraction from green mussel \(\textit{Perna viridis}\) Linnaeus
This study evaluated and optimized laboratory extraction methods for isolating and identifying microplastics from the tissues of green mussels, which accumulate plastic particles through their filter-feeding habits. Reliable extraction methods are essential for accurately quantifying microplastic contamination in shellfish consumed by humans.
Accumulation and ecotoxicological risk of weathered polyethylene (wPE) microplastics on green mussel (Perna viridis)
Green mussels exposed to weathered polyethylene microplastics for 30 days accumulated particles primarily in the intestine at higher concentrations, with reduced feeding rates at 3 µg/L but no mortality — while a post-exposure depuration period showed partial clearance from tissues.
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.
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.
Where are we? Towards an understanding of the selective accumulation of microplastics in mussels
This review synthesizes published research on how mussels selectively accumulate microplastics, examining what factors such as particle size, shape, polymer type, and environmental conditions influence which plastics end up in mussel tissue versus being rejected. The study aims to improve the use of mussels as bioindicator species for monitoring marine microplastic pollution by identifying key variables that affect accumulation patterns.
Microplastics effects on the physiology of the Mussel Perna perna (Bivalvia:Mytilidae)

Assessment of Microplastics in Green Mussel (Perna viridis) and Surrounding Environments around Sri Racha Bay, Thailand
Researchers assessed microplastic contamination in seawater, sediments, and green mussels (Perna viridis) around Sri Racha Bay, Thailand, finding seasonal variation with higher levels during the wet season and confirming that mussels bioaccumulate microplastics from their surrounding environment.
When nanoplastics (NPs) meet algae: Heteroaggregates exacerbate bioaccumulation, immunotoxicity, and microbial dysbiosis in the green mussel (Perna viridis)
Researchers exposed green mussels to nanoplastics alone and to heteroaggregates of nanoplastics combined with microalgae, finding that heteroaggregates increased nanoplastic uptake rates by 5.5-fold and tissue accumulation by 2.5-fold, while also exacerbating immunotoxicity and gut microbiota disruption.
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.
Occurrence and human health risks of microplastics in the Bay of Bengal using Perna viridis as sentinel species
Researchers found microplastics in water, sediment, and green mussel tissues at every site tested across five locations in the Bay of Bengal. The mussels showed tissue damage including inflammation and cell death linked to microplastic accumulation, with the digestive gland carrying the highest burden. Since these mussels are consumed by local communities, the findings raise direct concerns about human microplastic exposure through seafood.
Suspended micro-sized PVC particles impair the performance and decrease survival in the Asian green mussel Perna viridis
Researchers exposed aquatic organisms to suspended micro-sized PVC particles and found impaired performance and reduced survival, demonstrating that PVC-specific microplastics cause measurable harm at concentrations approaching those found in some polluted environments.
Nano-scale and micron-scale plastics amplify the bioaccumulation of benzophenone-3 and ciprofloxacin, as well as their co-exposure effect on disturbing the antioxidant defense system in mussels, Perna viridis
Researchers studied how nano- and micro-sized plastic particles affect the accumulation of benzophenone-3 and the antibiotic ciprofloxacin in green mussels. They found that smaller plastic particles enhanced the uptake of both chemicals into mussel tissues and caused greater disruption to the animals' antioxidant defense systems. The study demonstrates that plastic particle size matters when assessing how microplastics transport and amplify the effects of other environmental contaminants in marine organisms.
Metabolic responses of the marine mussel Mytilus galloprovincialis after exposure to microplastics of different shapes and sizes
Researchers exposed Mediterranean mussels to microplastics of different shapes and sizes and found that round particles and small fibers accumulated the most in mussel tissues. These same particle types caused the most significant metabolic changes, altering amino acid processing and vitamin pathways. The findings suggest that the shape and size of microplastics play an important role in determining how much harm they cause to marine filter-feeding organisms.
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.
