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.
Effects of sizes and concentrations of different types of microplastics on bioaccumulation and lethality rate in the green mussel, Perna viridis
Researchers investigated how different microplastic types, sizes, and concentrations affected bioaccumulation and mortality in green mussels, finding size- and concentration-dependent effects on MP accumulation in this filter-feeding species.
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.
Microplastics effects on the physiology of the Mussel Perna perna (Bivalvia:Mytilidae)
This Brazilian study exposed mussels (Perna perna) to polyethylene microplastics from cosmetics to examine whether effects are physical or chemical in nature. The study contributes to understanding of microplastic risks to filter-feeding shellfish that are widely consumed by humans.
Using marine mussels to assess the potential ecotoxicological effects of two different commercial microplastics
Researchers exposed marine mussels to polypropylene and polyethylene terephthalate microplastics for up to 28 days to evaluate ecotoxicological effects. They measured feeding rates, condition index, and various biochemical markers related to metabolism and oxidative stress. The study found measurable changes in the mussels' biological responses, suggesting that these common types of microplastics can affect the health of filter-feeding organisms in marine environments.
EFFECT OF MICROPLASTIC ON GREEN MUSSEL Perna viridis: EXPERIMENTAL APPROACH
Researchers experimentally exposed green mussels (Perna viridis) to microplastics under controlled laboratory conditions and observed effects on feeding activity, tissue accumulation, and physiological stress responses. The study provides empirical evidence that microplastic ingestion causes measurable biological harm in this commercially harvested bivalve species.
Comparative evaluation of high-density polyethylene and polystyrene microplastics pollutants: Uptake, elimination and effects in mussel
Researchers compared the accumulation, elimination, and biological effects of high-density polyethylene and polystyrene microplastics in mussels. Both types accumulated primarily in the digestive gland and gills and induced oxidative stress, though most particles were cleared after 144 hours of depuration. Metabolomic analysis revealed that the two polymers affected mussel metabolism differently, with polyethylene showing increased effects even during the elimination period.
Dynamic of small polyethylene microplastics (≤10 μm) in mussel's tissues
Mussels were exposed to a single dose of irregularly shaped HDPE particles (mainly ≤10 μm) followed by 7-day depuration, with particles accumulating in the digestive gland and gills over time and smaller fractions (≤4 μm) showing translocation from the digestive system to the gills. The study demonstrates that the smallest microplastic fractions persist longer and translocate to secondary tissues in bivalves.
Weathering impacts the uptake of polyethylene microparticles from toothpaste in Mediterranean mussels (M. galloprovincialis)
Researchers studied the uptake of weathered polyethylene microparticles from toothpaste by oral tissues, finding that environmental weathering of plastic particles affected their uptake behavior, with potential implications for human exposure through oral care products.
Microplastics, both non-biodegradable and biodegradable, do not affect the whole organism functioning of a marine mussel
Researchers exposed marine mussels to both conventional and biodegradable microplastics at environmentally realistic concentrations and measured whole-organism physiological responses including respiration, feeding, and energy balance. They found that neither type of microplastic significantly affected the mussels' overall functioning at these concentrations. The study suggests that while microplastic ingestion does occur, the biological impacts on filter-feeding organisms may be limited at the pollution levels currently found in natural ecosystems.
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.
Cellular and tissue-level responses of mussels (Mytilus edulis) to aged polyethylene terephthalate (PET) micro- and nanoplastic particles
This study exposed mussels to environmentally realistic concentrations of aged PET micro- and nanoplastics and found measurable cellular damage even at the lowest doses tested. The plastic particles caused inflammation, oxidative stress, and tissue changes in the mussels' digestive systems. Since mussels are a common seafood and are often eaten whole, these findings are relevant to understanding human microplastic exposure through shellfish consumption.
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.
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.
Physiological response measures (respiration, clearance, byssus production, survival) of Perna viridis during a 91 day exposure experiment to microplastics in Bogor, Indonesia, 2014
Green mussels from Jakarta Bay were exposed to PVC microplastics contaminated with fluoranthene for 91 days at varying concentrations, with physiological responses including respiration and filtration measured at the midpoint. The long-term controlled experiment examined whether chronic low-level microplastic exposure in tropical coastal environments impairs mussel health.
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.
Effects of environmentally relevant levels of polyethylene microplastic on Mytilus galloprovincialis (Mollusca: Bivalvia): filtration rate and oxidative stress
Researchers exposed Mediterranean mussels to polyethylene microplastics at environmentally relevant concentrations and found significant reductions in filtration rate and signs of oxidative damage in the digestive gland. The study suggests that microplastics as small as 40-48 micrometers can disrupt antioxidant defenses in bivalves even at low concentrations, raising concerns about their impact on marine filter-feeders.
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.
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.
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.
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.
Ingestion and effects from microplastic (polyethylene) derived from toothpaste on blue mussel (Mytilus galloprovincialis)
This study exposed blue mussels to polyethylene microplastics sourced directly from toothpaste and found that the particles caused physiological stress, reduced feeding activity, and elevated inflammatory markers. The results show that PE microbeads from consumer products can directly harm filter-feeding shellfish, raising concerns about human dietary exposure from seafood.
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.
Effect of aging of microplastics on gene expression levels of the marine mussel Mytilus edulis: Comparison in vitro/in vivo exposures
Researchers compared the effects of aged versus non-aged polyethylene microplastics on the marine mussel Mytilus edulis using both in vitro and in vivo exposures at environmentally relevant concentrations. The study found that gene expression changes in xenobiotic defense, immune function, and cell cycle control differed depending on whether the plastic was aged and the type of exposure method used. These findings highlight that the environmental weathering state of microplastics is an important factor in determining their biological effects on marine organisms.
