ClearUsing the Asian clam as an indicator of microplastic pollution in freshwater ecosystems
Researchers proposed the Asian clam as a bioindicator species for monitoring microplastic pollution in freshwater ecosystems, building on prior findings of high contamination rates in these organisms. Using a widely distributed filter feeder as a sentinel species could help standardize freshwater microplastic monitoring the way mussels are used in marine settings.
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.
Bivalves with potential for monitoring microplastics in South America

Influence of Microplastics on Freshwater Bivalves (Review)
This review analyzed studies on microplastic uptake, bioaccumulation, and biological effects in freshwater bivalves, which serve as both pollution sentinels and vectors for microplastic entry into food webs. The authors found consistent evidence for particle accumulation causing physiological stress, while calling for more standardized exposure protocols to improve cross-study comparability.
Tracking the micro- and nanoplastics in the terrestrial-freshwater food webs. Bivalves as sentinel species
Researchers tracked the transfer of micro- and nanoplastics through an experimental terrestrial-freshwater food chain involving earthworms, freshwater mussels, and predatory fish. The study found evidence of trophic transfer of plastic particles across species, with bivalves serving as effective sentinel organisms for monitoring plastic contamination in freshwater ecosystems.
Influence of microplastics on freshwater bivalves (review)
This review synthesized knowledge on how microplastics affect freshwater bivalves, covering ingestion, tissue accumulation, physiological stress responses, and reproductive impacts. Bivalves are shown to be sensitive bioindicators of microplastic contamination in rivers and lakes.
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.
Bivalve Mollusks as Biological Monitoring of Microplastic: A Review of Anadara antiquata and Gafrarium sp. in Indonesia
This Indonesian review examines two bivalve species (Anadara antiquata and Gafrarium sp.) as biological monitors of coastal microplastic contamination, synthesizing evidence that these filter feeders accumulate microplastics from seawater and serve as reliable sentinels for pollution in Indonesian coastal ecosystems.
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.
Occurrence of microplastics in bivalve molluscs Anomalocardia flexuosa captured in Pernambuco, Northeast Brazil
Researchers documented microplastic contamination in bivalve molluscs (Anomalocardia flexuosa) from estuaries in northeastern Brazil, finding widespread presence of microplastics in shellfish consumed by traditional communities, raising concerns about human dietary exposure.
Microplastics pollution in the South American Pantanal
Researchers sampled microplastics in the affluents and floodplains of the South American Pantanal wetland ecosystem, documenting this emerging threat to one of the world's largest tropical floodplains near urban pollution sources and in remote lowland areas.
Microplastics in rocky shore mollusks of different feeding habits: An assessment of sentinel performance
Researchers examined microplastic levels in three types of rocky shore mollusks with different feeding habits along a pollution gradient in Brazil. Filter-feeding oysters accumulated the most microplastics, followed by plant-eating limpets and meat-eating snails, suggesting that how an animal feeds affects how much plastic it ingests. The study proposes that all three species could serve as useful sentinel organisms for monitoring microplastic contamination in coastal areas.
Microplastic contamination in bivalves: First assessment in three coastal lagoons of the colombian caribbean, south america
Researchers conducted the first assessment of microplastic contamination in bivalves from three coastal lagoons, examining filter-feeding mollusks that concentrate suspended particles from surrounding waters. Microplastics were detected in bivalve tissues across all sites, establishing baseline contamination levels in these coastal ecosystems.
Microplastics in a mosaic of Marine Protected Areas from southeastern Brazil: An assessment based on filter-feeding bivalves
Researchers used filter-feeding bivalves as biological monitors to assess microplastic contamination across 28 marine protected areas along a heavily populated stretch of coastline in southeastern Brazil. They found microplastics in bivalves from all sites surveyed, demonstrating that protected status alone does not shield marine areas from plastic pollution. The study highlights how diffuse, transboundary plastic contamination reaches even designated conservation zones.
Unveiling microplastic pollution: Evaluating the role of Sinotaia quadrata (Caenogastropoda, Viviparidae) as a monitoring tool in freshwater ecosystems
Researchers evaluated whether the invasive freshwater snail Sinotaia quadrata could serve as a reliable monitoring tool for tracking microplastic pollution in waterways affected by human activity. The types and characteristics of microplastics found in the snails closely matched what was detected in the surrounding water and sediment. The study suggests that these snails could be a practical and cost-effective way to assess microplastic contamination levels in freshwater ecosystems.
Microplastic contamination in bivalves: First assessment in three coastal lagoons of the colombian caribbean, south america
Researchers assessed microplastic contamination in bivalves from three coastal lagoons, finding that filter-feeding species readily accumulate particles from surrounding water and sediment. The study characterized particle types and polymer compositions across different lagoon environments.
Bivalves as Biological Sieves: Bioreactivity Pathways of Microplastics and Nanoplastics
This review examines how filter-feeding bivalves like mussels and oysters process and accumulate microplastics and nanoplastics of different sizes. Researchers found that larger particles pass through relatively quickly in feces, while smaller microplastics and nanoplastics tend to accumulate in digestive tissues and immune cells with longer retention times, making bivalves valuable bioindicators of plastic pollution.

First Record of Microplastic Contamination in the Non-Native Dark False Mussel Mytilopsis leucophaeata (Bivalvia: Dreissenidae) in a Coastal Urban Lagoon
Researchers documented microplastic contamination for the first time in the invasive dark false mussel in a coastal lagoon in Rio de Janeiro, Brazil. Microplastics were found in all mussel samples, with fibers and fragments being the most common types, and thirteen different polymer types were identified. The study suggests this widespread filter-feeding species could serve as a useful bioindicator for monitoring microplastic pollution in coastal waters.
