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.
Combined ecotoxicity of polystyrene microplastics and Di-(2-ethylhexyl) phthalate increase exposure risks to Mytilus coruscus based on the bioaccumulation, oxidative stress, metabolic profiles, and nutritional interferences
Researchers exposed hard-shelled mussels to a common plastic additive (DEHP) and polystyrene microplastics together, and found that the microplastics increased how much DEHP accumulated in the animals' digestive organs. The combined exposure disrupted the mussels' antioxidant defenses and altered their metabolic processes more than either pollutant alone. The study suggests that microplastics can amplify the harmful effects of chemical pollutants in marine organisms.
Physiological and biochemical responses to caffeine and microplastics in Mytilus galloprovincialis
Researchers exposed Mediterranean mussels to caffeine and microplastics both separately and together to measure their combined effects. The combination caused greater oxidative stress and changes in cell function than either pollutant alone. While focused on mussels, the study is relevant to human health because mussels are widely eaten as seafood and can accumulate both microplastics and chemical contaminants.
Could Mussel Populations Be Differentially Threatened by the Presence of Microplastics and Related Chemicals?
Researchers exposed mussels to polyamide microplastics and the plastic additive tricresyl phosphate, both independently and in combination, for 28 days. Independent exposure significantly inhibited antioxidant and neurotransmitter enzyme activities, but when both contaminants were combined, most biomarker responses returned to control levels. A comparison between Atlantic and Mediterranean mussel populations revealed that baseline detoxification defenses differed, suggesting that different populations may respond differently to plastic-related contamination.
Co-exposure to Microplastics and Cadmium: Effects on DNA Damage in Mytilus Galloprovincialis
This study investigated how co-exposure to microplastics and cadmium affects DNA damage in the Mediterranean mussel Mytilus galloprovincialis. Microplastics acted as vectors for cadmium, and combined exposure resulted in greater genotoxic effects than either pollutant alone.
Beyond carrier effects: Polyamide microplastics and TCPP jointly drive physiological toxicity in mussels at environmental concentrations
Researchers exposed thick-shelled mussels to polyamide microplastics combined with the flame retardant TCPP at environmentally relevant concentrations. They found that the combined stress caused physiological toxicity through an adsorption effect rather than a simple carrier effect, with potentially irreversible damage to digestive glands. The study also showed that the internal bacterial diversity of exposed mussels was altered, indicating broader ecological consequences of microplastic-chemical co-exposure in marine environments.
Simultaneous exposure to microplastics and heavy metal lead induces oxidative stress, histopathological damage, and immune dysfunction in marine mussel Mytilus coruscus
When marine mussels were exposed to both microplastics and the heavy metal lead together, the combined effect was worse than either pollutant alone. The combination caused more severe tissue damage, higher oxidative stress, and greater immune system disruption, which is concerning because in real ocean environments, microplastics and heavy metals commonly occur together.
Ecotoxicological risk of microplastics for marine organisms
Italian researchers studied whether microplastics act as vectors for chemical pollutants by measuring how pyrene and cadmium adsorb onto polyethylene and polystyrene microplastics and transfer to mussels. They found evidence of contaminant transfer and cellular stress responses, raising concerns about the combined toxicity of microplastics and their associated chemicals.
Exposure of marine mussels Mytilus spp. to polystyrene microplastics: Toxicity and influence on fluoranthene bioaccumulation
Researchers exposed marine mussels to polystyrene microplastics alone and in combination with the pollutant fluoranthene to study their combined effects. They found that while the microplastics themselves had limited direct toxicity, they influenced how fluoranthene accumulated in and was cleared from the mussels' tissues. The study suggests that microplastics can alter the way marine organisms interact with chemical pollutants, potentially changing the risks these contaminants pose.
Alleviation of specific responses in the combined exposure of freshwater mussel Unio tumidus to psychoactive substances and microplastics
Researchers exposed freshwater mussels to a combination of common psychoactive substances (caffeine and chlorpromazine) and microplastics to see how the mixture affected their biology. Individually, each pollutant caused oxidative damage and disrupted cellular processes, but the combined mixture surprisingly reduced some of these harmful effects. The study suggests that pollutant interactions in real-world conditions can produce unexpected outcomes that differ from single-pollutant studies.
Single contaminant and combined exposures of polyethylene microplastics and fluoranthene: accumulation and oxidative stress response in the blue mussel,Mytilus edulis
Researchers exposed blue mussels to polyethylene microplastics and the toxic chemical fluoranthene — alone and together — finding that co-exposure reduced tissue fluoranthene concentrations but still triggered significant antioxidant stress responses in gills and digestive glands, without producing additive or synergistic toxic effects.
Potential genotoxicity impacts of a co-exposure of polypropylene microplastic and antibiotics to freshwater pearl mussel Hyriopsis cumingii (Lea, 1852)
Researchers assessed the genotoxic effects of combined polypropylene microplastic and antibiotic (sulfamethoxazole and oxytetracycline) exposure in freshwater pearl mussels. Co-exposure produced greater DNA damage and oxidative stress than either contaminant alone, indicating synergistic genotoxicity in this commercially important species.
The Combined Effects of Cadmium and Microplastic Mixtures on the Digestion, Energy Metabolism, Oxidative Stress Regulation, Immune Function, and Metabolomes in the Pearl Oyster (Pinctada fucata martensii)
Researchers studied the combined effects of cadmium and microplastics on pearl oysters, measuring impacts on digestion, energy use, immune function, and metabolism. They found that co-exposure to both pollutants caused more severe damage than either alone, disrupting the oysters' antioxidant defenses and metabolic processes. The study highlights the compounding threat that metal and microplastic pollution together pose to marine shellfish.
Combined toxic effects of nanoplastics and norfloxacin on antioxidant and immune genes in mussels
Researchers studied the combined toxic effects of polystyrene nanoplastics and the antibiotic norfloxacin on mussels, focusing on genes related to antioxidant defense and immune function. They found that the mixture of both contaminants produced more severe disruptions to gene expression than either substance alone, indicating a synergistic toxic effect. The study suggests that the co-occurrence of nanoplastics and antibiotics in marine environments may pose compounding risks to shellfish health.
The combined effects of polystyrene microplastics and temperature stress on Mytilus galloprovincialis, Lamarck, 1819
Researchers investigated the combined effects of polystyrene microplastics and rising water temperatures on Mediterranean mussels. The study found that microplastic exposure amplified temperature-related stress, leading to increased mortality, greater oxidative damage, and more severe tissue changes, suggesting that these two environmental stressors interact to worsen harm to marine organisms.
Unraveling the toxic trio: Combined effects of thifluzamide, enrofloxacin, and microplastics on Mytilus coruscus
Researchers examined the combined effects of the pesticide thifluzamide, the antibiotic enrofloxacin, and polystyrene microplastics on mussels over four weeks. They found that co-exposure increased the accumulation of both chemicals in mussel tissue and worsened oxidative damage, neurotoxicity, and metabolic disruption compared to single exposures. The study suggests that the presence of microplastics in waterways can amplify the harmful effects of pesticides and antibiotics on edible shellfish.
Immunotoxicity of petroleum hydrocarbons and microplastics alone or in combination to a bivalve species: Synergic impacts and potential toxication mechanisms
Marine mussels exposed to petroleum hydrocarbons and microplastics separately and together showed that combined exposure caused greater immune suppression and lysosomal damage than either stressor alone, identifying oxidative stress pathways as a key mechanism of joint toxicity.
Toxicity evaluation of the combination of emerging pollutants with polyethylene microplastics in zebrafish: Perspective study of genotoxicity, mutagenicity, and redox unbalance
Researchers exposed adult zebrafish to polyethylene microplastics combined with a mixture of common water pollutants for 15 days and assessed DNA damage, mutation rates, and oxidative stress. They found that microplastics alone caused DNA damage and nuclear abnormalities as severe as those caused by the pollutant mixture, challenging the assumption that microplastics are less harmful than chemical contaminants. The study revealed that the fish's antioxidant defenses were overwhelmed across multiple organs, suggesting widespread oxidative damage from microplastic exposure.
Combined effects of polyamide microplastics and the pathogenic bacterium Vibrio parahaemolyticus on the immune parameters of Mytilus coruscus
When mussels were exposed to nylon microplastics along with harmful Vibrio bacteria, they suffered gill damage, increased oxidative stress, and weakened immune defenses compared to either stressor alone. The combined exposure suppressed key immune enzymes that mussels need to fight infection. Since mussels are widely consumed as seafood, this study raises concerns that microplastic-contaminated shellfish could carry more pathogens and be less safe to eat.
Combined exposure of the bivalve Mytilus galloprovincialis to polyethylene microplastics and two pharmaceuticals (citalopram and bezafibrate): Bioaccumulation and metabolomic studies
Researchers exposed Mediterranean mussels to polyethylene microplastics combined with two pharmaceutical drugs and found that the microplastics altered how the drugs accumulated in mussel tissue and changed the organisms' metabolic responses. The combined exposures caused different metabolic disruptions than single exposures, and not all effects were reversed after a recovery period. This highlights how microplastics in the ocean can interact with pharmaceutical pollution to create unexpected biological effects in seafood species.
