ClearCombined toxic effects of nanoplastics and norfloxacin on mussel: Leveraging biochemical parameters and gut microbiota
Researchers exposed mussels to nanoplastics and the antibiotic norfloxacin, both alone and together, and found that the combination caused greater biochemical stress than either pollutant alone. Nanoplastics appeared to carry the antibiotic into mussel tissues, increasing its bioavailability and impact on gut microbiota. The findings suggest that nanoplastics can amplify the toxicity of other contaminants in marine organisms.
Hetero-Aggregation of Nanoplastics with Freshwater Algae and the Toxicological Consequences: The Role of Extracellular Polymeric Substances
Researchers studied how polystyrene and polylactic acid nanoplastics hetero-aggregate with the alga Chlorella vulgaris, finding that extracellular polymeric substances released by algae strongly influenced aggregation behavior and that aggregation altered the toxicity of nanoplastics.
Hitchhikers in bivalve immune system: Mixed microplastics and nanoplastics triggers hemocyte autophagy
Researchers exposed bivalves to mixed microplastic and nanoplastic suspensions of multiple sizes and quantified the effects on hemocyte immune cell populations over time. Heterogeneous MNP mixtures reshaped hemocyte subpopulations non-additively, altering immune function in ways that single-size exposure studies would not predict.

Immunological responses, oxidative stress, and histopathological effects of nanoplastics on commercially relevant mussel species: A review
This review examines how nanoplastics affect commercially important mussel species, finding that these tiny particles can cross biological barriers and accumulate in tissues. Evidence indicates that nanoplastic exposure alters metabolic rates, triggers immune responses, causes oxidative stress and DNA damage, and changes the structure of gills, gonads, and gut tissue. The findings raise concerns about both mussel health and potential implications for seafood safety.
Comparative role of microplastics and microalgae as vectors for chlorpyrifos bioacumulation and related physiological and immune effects in mussels
Researchers compared microplastics and microalgae as vectors for chlorpyrifos transfer into mussels, finding that both particle types facilitated pesticide bioaccumulation with distinct physiological and immune effects on the organisms.
The combined effects of phenanthrene and micro-/nanoplastics mixtures on the cellular stress responses of the thick-shell mussel Mytilus coruscus
Scientists exposed thick-shell mussels to a combination of micro- and nanoplastics along with a common pollutant (phenanthrene) to study their combined effects. The mixtures caused more severe immune cell damage, increased oxidative stress, and stronger inflammatory responses than either pollutant alone. Evidence indicates that micro- and nanoplastics can worsen the toxic effects of organic pollutants in marine shellfish.
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.
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.
Heteroaggregates of Polystyrene Nanospheres and Organic Matter: Preparation, Characterization and Evaluation of Their Toxicity to Algae in Environmentally Relevant Conditions
Polystyrene nanospheres combined with natural organic matter to form heteroaggregates were found to be more toxic to algae under realistic environmental conditions than pristine nanoplastics, highlighting how environmental transformation of nanoplastics can alter their ecological risk.
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.
When microplastics meet microalgae: Unveiling the dynamic formation of aggregates and their impact on toxicity and environmental health
Researchers studied what happens when microplastics and algae meet in water, finding that algae colonize plastic surfaces and form clumps that absorb more toxic metals like copper than bare microplastics alone. This matters for human health because these microplastic-algae clumps can concentrate pollutants in aquatic food chains that eventually lead to the seafood on our plates.
Impact of microplastics pollution on ciprofloxacin bioaccumulation in the edible mussel (Perna viridis): Implications for human gut health risks
Researchers studied how microplastics affect the accumulation of the antibiotic ciprofloxacin in edible green mussels from a mariculture farm. They found that microplastics altered the way mussels absorbed and retained the antibiotic, with implications for human gut health when contaminated seafood is consumed. The study highlights the compounding food safety risks when multiple pollutants interact in aquaculture environments.
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.
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.
Exposure to microplastics renders immunity of the thick-shell mussel more vulnerable to diarrhetic shellfish toxin-producing harmful algae
Researchers found that mussels previously exposed to microplastics became more vulnerable to toxic algae blooms, suffering greater immune system damage than mussels without prior microplastic exposure. The microplastics weakened the mussels' defenses by causing oxidative stress, cell death, and energy depletion, leaving them less able to fight off the algal toxins. Since mussels are widely consumed as seafood, this combined threat could affect both marine ecosystems and food safety for humans.
An ecotoxicological approach towards the understanding of the impacts of micro- and nanoplastics in the marine environment
This PhD thesis investigated how micro- and nanoplastics affect marine microalgae and associated microbial consortia, examining how extracellular polymeric substances mediate plastic-biota interactions and how these effects cascade to higher trophic levels in marine food webs.
Effects of nanoplastics on clam Ruditapes philippinarum at environmentally realistic concentrations: Toxicokinetics, toxicity, and gut microbiota
Researchers exposed clams to nanoplastics at concentrations found in real marine environments and tracked how the particles accumulated in their tissues over 14 days. The nanoplastics caused physical damage and significantly altered the clams' gut bacteria. This is concerning because clams are widely consumed seafood, meaning nanoplastic contamination could affect both marine ecosystems and human food sources.
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.
Impact of nanoplastics on hemolymph immune parameters and microbiota composition in Mytilus galloprovincialis
Mytilus galloprovincialis mussels exposed to amino-modified polystyrene nanoplastics for 96 hours showed disrupted hemolymph immune parameters and significant shifts in microbiota composition, suggesting nanoplastics alter both immune function and the microbial communities mussels rely on.
Exposure to nanoplastics affects the outcome of infectious disease in phytoplankton
Researchers exposed a cyanobacterium-fungal parasite system to polystyrene nanoplastics and found that at high concentrations, NPs formed heteroaggregates with phytoplankton cells, altered host-parasite dynamics, and disrupted disease outcomes in an ecologically relevant model.
Microplastics aggravate the bioaccumulation of three veterinary antibiotics in the thick shell mussel Mytilus coruscus and induce synergistic immunotoxic effects
Researchers studied how polystyrene microplastics interact with three common veterinary antibiotics in thick shell mussels. The study found that when microplastics and antibiotics were present together, mussels accumulated significantly more antibiotics in their tissues and suffered worse immune damage than from either pollutant alone. This synergistic effect included reduced immune cell counts, increased oxidative stress, and disrupted immune gene expression, suggesting that microplastic pollution may amplify the harmful effects of antibiotic contamination in coastal waters.
Mercury interactions with algal and plastic microparticles: Comparative role as vectors of metals for the mussel, Mytilus galloprovincialis
Researchers compared the role of microplastics and microalgae as mercury vectors in mussels (Mytilus galloprovincialis), finding that microplastic-bound mercury had lower clearance rates (82%) than microalgae-bound mercury (95%) but resulted in higher total Hg accumulation and elimination. Despite facilitating Hg entry, microplastics also promoted faster Hg elimination, with mercury accumulating primarily in the digestive gland rather than the gills of MP-exposed mussels.
Microplastic interactions with freshwater microalgae: Hetero-aggregation and changes in plastic density appear strongly dependent on polymer type
Researchers studied interactions between microplastics and freshwater microalgae, finding that microplastics can physically attach to algal cells to form hetero-aggregates, altering both particle behavior and algal physiology.
