ClearImmunotoxicity 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.
Beyond Single Stressors: Integrated Physiological and Transcriptomic Responses of Argopecten irradians Exposed to Polystyrene and Toxic Dinoflagellates
Researchers exposed bay scallops to polystyrene microplastics and toxic algae both individually and in combination, finding that while survival remained above 90%, the combined exposure triggered elevated oxidative stress markers and more complex physiological disruption. Transcriptomic analysis revealed that microplastics primarily interfered with endocrine function while the toxic algae affected immune pathways, and co-exposure produced synergistic effects on metabolism and developmental regulation.
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.

Researchers used whole-transcriptome sequencing to study how mussels respond at the molecular level to combined exposure to PVC microplastics and cadmium. They found that the combined pollutants triggered distinct gene expression patterns, particularly in non-coding RNAs involved in immune and stress responses. The study suggests that microplastics and heavy metals together may cause more complex biological effects than either pollutant alone.
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.
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.

The study reveals mechanistic interactions between two co-occurring freshwater pollutants at the cellular metabolic level.
Multi-Biomarker Responses of Asian Clam Corbicula fluminea (Bivalvia, Corbiculidea) to Cadmium and Microplastics Pollutants
Researchers exposed Asian clams to cadmium, microplastics, and their mixtures, then measured a battery of biomarkers including oxidative stress, energy metabolism, and neurotoxicity indicators. They found that the combined exposure to cadmium and microplastics produced interactive effects that differed from exposure to either contaminant alone. The study demonstrates that microplastics can modify the toxicity of heavy metals in freshwater bivalves, highlighting the importance of studying pollutant mixtures rather than individual contaminants.
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.
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.
