ClearMicroplastics, Additives, and Plasticizers in Freshwater Bivalves: Preliminary Research of Biomonitoring
Researchers placed freshwater mussels in three rivers in central Italy to study how they accumulate microplastics, plasticizers, and additives over time. They found small microplastics and chemical additives in both the gills and digestive tracts of the mussels, with polyamide being the most common polymer detected. The study demonstrates that freshwater bivalves can serve as effective biological monitors for tracking microplastic pollution in rivers.

The study contributes to understanding microplastic impacts on freshwater bivalves that are important for ecosystem function and serve as indicators of water quality.
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.
Mytilus spp. as sentinels for monitoring microplastic pollution in Norwegian coastal waters: A qualitative and quantitative study
Researchers collected mussels from 15 sites along Norway's coastline and found microplastics at nearly every location, with remote Arctic sites containing surprisingly high levels — often more than sites near major cities. The study confirms that mussels are useful sentinels for monitoring microplastic pollution in coastal waters, with fibers making up 83% of all particles found.
Assessment of the impact of aquaculture facilities on transplanted mussels (Mytilus galloprovincialis): Integrating plasticizers and physiological analyses as a biomonitoring strategy
Researchers assessed microplastic impacts on mussels transplanted near aquaculture facilities by integrating plasticizer analysis with physiological biomarkers, finding that proximity to aquaculture infrastructure increased both particle ingestion and chemical plasticizer exposure.
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.
Micro and Nanoplastic Contamination and Its Effects on Freshwater Mussels Caged in an Urban Area
Researchers placed freshwater mussels at various sites around Montreal to measure microplastic and nanoplastic contamination in urban waterways. They found that mussels at rainfall overflow sites and downstream of the city center accumulated the most plastic particles, with nanoplastics correlating strongly with oxidative damage markers in tissue. The study suggests that tire wear and road erosion from stormwater runoff are important sources of plastic contamination for aquatic organisms.
