ClearMicroplastics, 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.

Efficacy of freshwater pearl mussel (Lamellidens marginalis) as a biomonitoring tool for assessing microplastic pollution
Laboratory experiments showed that freshwater pearl mussels readily ingested microplastic particles, which then accumulated in their organs and tissues and caused measurable histological damage. This is relevant because freshwater mussels are widely used as biomonitors of water quality, and the findings confirm they can serve as indicators of microplastic pollution while also showing that this pollution harms them.

Researchers assessed the Mediterranean mussel Mytilus galloprovincialis as a bioindicator for microplastic pollution, focusing on improving quantification of small microplastics below 25 µm that conventional methods miss. Mussels were found to accumulate microplastics efficiently across size ranges, validating their use as biomonitors while highlighting the need for improved analytical methods.
Accumulation of microplastics in the bivalve mollusc Unio tumidus under experimental and field exposures
Researchers found that the freshwater bivalve Unio tumidus accumulates microplastics in its tissues under both laboratory and field conditions, with accumulation rates dependent on particle concentration and exposure duration, confirming this species as a viable biomonitor for freshwater MP pollution.
Accumulation of microplastics in bivalves within the Chandragiri River in South-Western India
This study investigated microplastic accumulation in bivalves from the Chandragiri River in South-Western India. Researchers found that these filter-feeding organisms had accumulated microplastics of various types and sizes, underscoring the capacity of bivalves to serve as bioindicators for monitoring microplastic pollution in river ecosystems.
Assessing the relationship between the abundance and properties of microplastics in water and in mussels
Researchers investigated the relationship between microplastic levels in coastal waters and in mussels at 25 sites along China's coastline. They found a strong positive correlation, meaning that mussels in more polluted waters contained more microplastics, and that mussels preferentially ingested smaller particles. The study supports the use of mussels as biological indicators for monitoring microplastic contamination in marine environments.
Tracking the microplastic pollution in the freshwater environments of southeastern Türkiye: Usage of Unio delicatus, Unio Terminalis and Dreissena polymorpha as bioindicators of microplastics
This study examined microplastic contamination in three freshwater mussel species collected from rivers and a dam lake in southeastern Turkey, finding relatively low average concentrations (under 1 microplastic per individual) but confirming that these mussels do accumulate plastic particles from their surroundings. Because mussels are filter feeders with a fixed lifestyle, they reflect local pollution levels well, making them useful sentinels for tracking microplastic contamination in freshwater ecosystems. The research adds to growing evidence that microplastics are now present even in inland freshwater species far from the ocean.
Bioaccumulation of emerging contaminants in mussel (Mytilus galloprovincialis): Influence of microplastics
Researchers investigated whether microplastics influence the bioaccumulation of emerging contaminants in Mediterranean mussels. The study found that the presence of microplastics altered how certain chemical pollutants accumulated in mussel tissue, suggesting that microplastics can act as carriers that change the uptake and distribution of other contaminants in marine organisms.
Peran Organisme Sessile Sebagai Bioindikator Mikroplastik Di Ekosistem Pesisir: Systematic Literature Review
This systematic literature review synthesizes evidence on how sessile coastal organisms — particularly bivalves like mussels and oysters — accumulate microplastics through their filter-feeding behavior, making them useful biological indicators of contamination. The review found that fibers dominate across most species and locations, and that polyethylene, polypropylene, and PET are the most common polymer types. Because these organisms are widely consumed by humans and are sensitive to environmental changes, they serve as both ecological sentinels and a potential pathway for microplastic exposure in human diets.
Effects of microplastics contamination on marine biota
Researchers exposed mussels to PVC microplastics under different conditions, finding that short-term exposure caused physiological stress influenced by plastic additives and concentration, while long-term exposure allowed some adaptation. Microplastics were transferred along the food chain to predators but were not absorbed into tissues, suggesting physical passage rather than bioaccumulation.
High microplastic exposure affects survival and health of Dreissena spp. mussels: implications for freshwater pollution monitoring
Researchers tested whether Dreissena mussels could serve as bioindicators for freshwater microplastic pollution by exposing them to polyethylene microbeads for two months. At high concentrations, the mussels showed decreased health indicators and increased mortality within 15 days, while lower concentrations had no significant effect. The study supports using these filter-feeding mussels as practical biological monitors for assessing microplastic contamination levels in freshwater ecosystems.
Using mussel as a global bioindicator of coastal microplastic pollution
This review evaluates whether mussels can serve as reliable global indicators of coastal microplastic pollution. Researchers found that mussels are well suited for this role due to their wide geographic distribution, filter-feeding behavior, and demonstrated ability to accumulate microplastics from surrounding waters. The study identifies remaining challenges in standardizing monitoring methods but concludes that mussels offer a practical and ecologically relevant tool for tracking marine microplastic contamination.
Binational survey using Mytilus galloprovincialis as a bioindicator of microplastic pollution: Insights into chemical analysis and potential risk on humans
Researchers conducted surveys of microplastic contamination in mussels from coastal sites across Morocco and Tunisia, finding plastics in 79 to 100 percent of all samples. The most common types were polyethylene and polypropylene fibers and fragments, with chemical analysis revealing the presence of associated toxic additives. The study estimates that regular mussel consumers in these regions face meaningful microplastic intake, highlighting a potential human health concern.
Towards Risk Assessments of Microplastics in Bivalve Mollusks Globally
Researchers compiled data from 22 countries to assess the risk of microplastic contamination in bivalve mollusks such as mussels and oysters.
