ClearInvestigating the combined effects of microplastics and suspended sediment on mussels in controlled experimental conditions.
Researchers investigated the combined effects of microplastics and suspended sediment on mussels under controlled experimental conditions, examining how co-exposure to these two particulates alters physiological responses compared to single-stressor exposures. The study addressed interactions between two common aquatic stressors to better predict realistic environmental impacts on filter-feeding bivalves.
Exploring the effect of microparticles on bivalves: Exposure of Mytilus galloprovincialis and Ruditapes philippinarum to both microplastics and silt
Researchers exposed mussels and clams to polyethylene microplastics, natural silt particles, and a combination of both, finding that the mixture caused significantly worse mortality and oxidative stress than either substance alone. Clams were more sensitive to microplastic exposure than mussels, while mussels retained more microplastics in their tissues. The study reveals that the combined presence of natural sediment particles and microplastics in coastal waters creates synergistic harmful effects on filter-feeding shellfish that are greater than the sum of individual exposures.
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.
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.
Microplastics can aggravate the impact of ocean acidification on the health of mussels: Insights from physiological performance, immunity and byssus properties
Researchers found that the combination of ocean acidification and microplastic exposure weakened mussel immune systems, reduced feeding performance, and degraded the quality of byssus threads used for attachment. The study suggests that co-occurring ocean acidification and microplastic pollution could increase the vulnerability of bivalves to disease and dislodgement, threatening their survival in future marine environments.
Combined effect of microplastic, salinomycin and heating on Unio tumidus
Researchers studied how microplastics interact with a common veterinary antibiotic and elevated water temperatures to affect freshwater mussels. While microplastics and the antibiotic alone caused mild stress, the combination under warmer conditions dampened the mussels' protective enzyme responses rather than amplifying them. This finding highlights that the effects of microplastics cannot be studied in isolation, as real-world conditions involve multiple stressors that interact in complex and sometimes unexpected ways.
Optimization of experimental conditions for exposure of larval mussels (Mytilus californianus) to microplastic particles
Researchers optimized an exposure system for testing the effects of microplastic particles on larval mussels (Mytilus californianus), addressing the challenge of keeping particles suspended and preventing clumping during experiments. Establishing reliable exposure protocols is critical for generating accurate ecotoxicology data on how microplastics affect early-life-stage marine bivalves, which are commercially important and ecologically sensitive.
Impact of environmental microplastics alone and mixed with benzo[a]pyrene on cellular and molecular responses of Mytilus galloprovincialis
Researchers exposed Mediterranean mussels to environmentally collected microplastics from a beach, both alone and combined with the pollutant benzo[a]pyrene, at ecologically relevant concentrations. The study found that even short-term exposure caused cellular and molecular responses in the mussels, and the combination of microplastics with chemical pollutants produced different effects than either contaminant alone.
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.
Marine mussel metabolism under stress: Dual effects of nanoplastics and coastal hypoxia
This study examined how nanoplastics and low oxygen levels together affect marine mussels, finding that both stressors disrupted the animals' internal balance and energy metabolism. The combination of nanoplastics and oxygen-depleted water was more harmful than either stressor alone, damaging cellular defenses against oxidative stress. Since mussels are widely consumed as seafood, these findings raise questions about the safety of shellfish harvested from polluted, oxygen-poor coastal waters.
Elucidating the consequences of the co-exposure of microplastics jointly to other pollutants in bivalves: A review
This review examines studies on the combined effects of microplastics and other pollutants in bivalves, finding that co-exposure often modifies individual toxicant effects and highlighting bivalves as important sentinel species for monitoring complex environmental contamination.
Assessing the physiological effects of microplastics on cultured mussels in the Mediterranean Sea
Researchers combined laboratory experiments with computer modeling to assess how microplastics affect farmed Mediterranean mussels. They found that while microplastics reduced the mussels' ability to filter food, the overall impact on growth over a mussel's lifetime was relatively small under current pollution levels. However, the study suggests that in areas with higher microplastic concentrations, the effects on mussel farming could become more significant.
Unraveling the interplay between environmental microplastics and salinity stress on Mytilus galloprovincialis larval development: A holistic exploration
Researchers studied how environmental microplastics and increased salinity together affect the early development of Mediterranean mussel larvae. The combination caused larval deformities, developmental problems, and changes in gene activity related to shell formation, stress response, and cell damage. These findings are concerning because climate change is altering ocean salinity in coastal areas where microplastic pollution is also heavy, and mussels are a food source that could pass accumulated microplastics to humans.
Combined effects of microplastics and nitrogen on bivalve‐mediated biogeochemical cycling
Researchers investigated the combined effects of microplastic pollution and excess nitrogen on coastal sediment ecosystems mediated by bivalves. They found that when both stressors were present together, nitrogen processing responses changed in ways not seen with either stressor alone, and sediment health conditions worsened significantly. The study suggests that multiple environmental stressors can interact in unexpected ways that single-stressor studies would miss.
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.
The multiple responses of Mytilus galloprovincialis in the multi-stressor scenario: Impacts of low pH, low dissolved oxygen, and microplastics
Researchers exposed Mediterranean mussels to the combined stressors of low pH, low dissolved oxygen, and microplastics for 15 days. While whole-organism functions like respiration were unaffected, the study found significant cellular-level impacts, suggesting that microplastics interact with ocean acidification and deoxygenation to cause subtle but measurable stress in marine invertebrates.
Synthesized effects of medium-term exposure to seawater acidification and microplastics on the physiology and energy budget of the thick shell mussel Mytilus coruscus
Researchers found that combined exposure to ocean acidification and microplastics significantly reduced the feeding rate, food absorption, and energy budget of the thick shell mussel Mytilus coruscus, with acidification amplifying the negative effects of microplastics.
Extraction and identification of microplastics from mussels: Method development and preliminary results
Scientists developed and validated a method for extracting and identifying microplastics from mussel tissue, then applied it to measure contamination in commercially harvested mussels. The method produced reliable, reproducible results, providing a practical tool for monitoring microplastic levels in one of the world's most widely consumed shellfish.
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.
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.
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.
Are microplastics impacting shellfish?
Researchers investigated whether microplastic contamination measurably impacts shellfish physiology, growth, reproduction, and health outcomes, assessing the ecological and food safety implications of microplastic exposure in commercially and ecologically important bivalve species.
The effect of climate change and microplastics on the physiology of marine invertebrates of economic interest
This thesis examines how climate change and microplastic pollution interact to affect the physiology of marine invertebrates important for aquaculture. Combined stressors were found to have compounding effects on organisms like mussels and oysters, threatening both ecosystems and food security.
Biomarker responses of marine mussels (Mytilus galloprovincialis) experimentally exposed to emerging contaminants: pharmaceuticals and microplastics.
Researchers exposed marine mussels to the antibiotic clarithromycin, the antidepressant venlafaxine, and polystyrene microplastics alone and in combination, finding that the pharmaceuticals caused oxidative stress but that co-exposure with microplastics diminished these effects, likely because microplastics sequestered the drugs.
