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.

Toxic Impact of Polystyrene Microplastics (PS-MPs) on Freshwater Mussel Lamellidens marginalis
Researchers exposed freshwater mussels to polystyrene microplastic fibers for up to 15 days and measured changes in biochemical parameters across multiple tissues. The study found reduced protein levels and enzyme activity changes in gills, hepatopancreas, mantle, and foot tissues, with the integrated biomarker response indicating progressively worsening physiological stress over the exposure period.
Insights into the Response in Digestive Gland of Mytilus coruscus under Heat Stress Using TMT-Based Proteomics
Researchers investigated how heat stress affects the digestive gland of thick-shelled mussels using advanced protein analysis techniques. They found significant changes in proteins related to immune defense, energy metabolism, and stress response, revealing the biological mechanisms behind heat-related mussel die-offs. While focused on temperature stress, the study provides foundational knowledge about mussel resilience that is relevant to understanding how environmental stressors, including pollutants, affect these important marine organisms.
Effects of Acute Ammonia Stress on Antioxidant Responses, Histopathology and Ammonia Detoxification Metabolism in Triangle Sail Mussels (Hyriopsis cumingii)
Triangle sail mussels exposed to sub-lethal ammonia concentrations showed antioxidant enzyme activation followed by inhibition, with the highest stress responses in gills and hepatopancreas and histopathological damage suggesting oxidative stress as a key mechanism of ammonia toxicity.
The use of green mussel as bioindicator of heavy metal pollution in Indonesia: a review
This review covers the use of Asian green mussel Perna viridis as a bioindicator of heavy metal pollution in Indonesian waters, summarizing studies on metal accumulation in mussel tissue relative to water quality and discussing implications for seafood safety.
Microplastic intake and enzymatic responses in Mytilus galloprovincialis reared at the vicinities of an aquaculture station
Researchers evaluated antioxidant defenses and oxidative stress markers in gills of Mediterranean mussels (Mytilus galloprovincialis) reared near an aquaculture station, finding that microplastics derived from aquaculture activities induced significant enzymatic stress responses.
Biological effects of contaminants in mussels (Mytilus trossulus) transplanted in northern Baltic Sea coastal areas
This thesis used biomarkers in mussels transplanted to contaminated coastal sites in the northern Baltic Sea to assess the effects of various pollutants on mussel health. The work demonstrates how mussels can serve as sensitive indicators of environmental contamination in coastal areas affected by multiple human activities.
Transcriptional Responses as Biomarkers of General Toxicity: A Systematic Review and Meta-analysis on Metal-Exposed Bivalves
This meta-analysis found that metallothionein and heat shock protein 70 are the most reliable transcriptional biomarkers for detecting metal toxicity in bivalves, showing consistent upregulation across different metal types and concentrations. These biomarkers could improve environmental monitoring of metal contamination in aquatic ecosystems.
Effects of exposure to nanoplastics on the gill of mussels Mytilus galloprovincialis: An integrated perspective from multiple biomarkers
Researchers exposed Mediterranean mussels to polystyrene nanoplastics for seven days and measured multiple gill biomarkers, finding that nanoplastics triggered oxidative stress, inhibited acetylcholinesterase, disrupted sodium-potassium ion transport, and impaired energy and lipid metabolism, pointing to broad physiological interference in marine invertebrates.
Mikroplastens intåg i den limnologiska miljön - Allmän dammussla (Anodonta anatina) innehåller mikroplast
This Swedish study exposed freshwater mussels (Anodonta anatina) to microplastics and examined uptake and potential health effects, finding that mussels ingest microplastics and that higher exposures affected their physiology. The study contributes to understanding microplastic impacts on freshwater bivalves that are important for ecosystem function and serve as indicators of water quality.
Microplastics, Additives, and Plasticizers in Freshwater Bivalves: Preliminary Research of Biomonitoring
Freshwater mussels (Anodonta cygnea) deployed in three Italian rivers accumulated microplastics primarily in their gills and digestive tracts, with polyamide (nylon) fibers being the most common type found. The study also detected plasticizers and additives within the bivalves, demonstrating that these organisms can serve as effective sentinels for monitoring the full chemical footprint of plastic pollution in river systems.
Population-dependent stress response of bivalve mollusc Unio tumidus to ibuprofen, microplastic and their mixture
Researchers exposed freshwater mussels (Unio tumidus) from both pristine and contaminated populations to ibuprofen, polyethylene microplastics, and their combination for 14 days, comparing antioxidant enzyme responses, oxidative damage markers, and lysosomal stability. They found population-dependent differences in stress responses, with the contaminated population showing more pronounced reactions to ibuprofen and the pristine population responding more strongly to microplastics alone.

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.

Mussels as integrative sentinels of emerging contaminants in aquatic ecosystems.
Scientists are using mussels like underwater detectors to monitor pollution in our water, including medicines, personal care products, and microplastics that are hard to track with regular testing methods. This research review shows that mussels are excellent at soaking up these pollutants from water over time, giving us a better picture of what contamination exists in our lakes, rivers, and oceans. This matters because these same pollutants can affect the safety of our drinking water and seafood.
