ClearUnraveling 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.
Molecular mechanisms controlling physiological plasticity in marine mussels under the influence of natural and anthropogenic stress factors
This thesis project investigated the molecular mechanisms that help Mediterranean mussels cope with environmental stress, including both natural factors and emerging pollutants like microplastics. Understanding these stress responses could help predict how marine shellfish will fare as pollution and climate change intensify.
Mussel: a potential pollution indicator in the aquatic ecosystem and effect of climate change
This review examines the biology and ecology of mussels as environmental indicator organisms, covering how they respond to pollution, temperature, and other stressors including microplastics. Mussels are widely used as bioindicators of marine pollution because they filter large volumes of water and accumulate contaminants including microplastic particles in their tissues.
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.

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.
Omics insights in responses of bivalves exposed to plastic pollution
This review examined how advanced molecular analysis technologies are being used to understand how bivalves like mussels and oysters respond to microplastic and nanoplastic exposure at the genetic and protein level. Researchers found that plastic pollution disrupts bivalve behavior, metabolism, and reproduction, and that molecular-level analysis can reveal early warning signs of harm not visible through traditional observation. The findings are relevant to both marine conservation and human food safety, since bivalves are widely consumed seafood that accumulate plastic particles.
Physiological and transcriptome analysis of Mytilus coruscus in response to Prorocentrum lima and microplastics
The combined effects of diarrhetic shellfish toxin and microplastics on the mussel Mytilus coruscus were assessed at physiological and transcriptomic levels, revealing synergistic disruption of immune function, antioxidant responses, and metabolic pathways. The study provides molecular-level evidence of interactive toxicity between two common coastal contaminants.
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.
Marine Pollution: Mytilus Galloprovincialis as a Model Organism to Assess Micro- and Nanoplastic Impact

Exposure of Mytilus galloprovincialis to Microplastics: Accumulation, Depuration and Evaluation of the Expression Levels of a Selection of Molecular Biomarkers
Researchers exposed Mediterranean mussels to a realistic mixture of microplastic types and then tested whether a standard purification process could remove them. They found that purification significantly reduced microplastic contamination in the mussels and that molecular biomarkers in the gills could detect the biological effects of exposure. The study suggests that both purification protocols and molecular monitoring tools could help address microplastic risks in farmed shellfish.
Investigating 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 simultaneous exposure to both stressors affects physiological responses compared to exposure to either stressor alone.
Differential responses of selectively bred mussels (Perna canaliculus) to heat stress—survival, immunology, gene expression and microbiome diversity
This study examined how selectively bred green-lipped mussels respond to heat stress, finding that genetic background significantly influenced survival rates, immune responses, and gene expression during heat challenges. While not directly about microplastics, the research is relevant because environmental stressors like microplastic pollution can compound heat stress effects on shellfish. Understanding how marine organisms cope with stress helps predict how additional pressures from plastic pollution might affect seafood species.
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.
