ClearUnveiling the hidden impacts: A comprehensive review of microplastic effects on marine bivalves
This review synthesizes research on how microplastics accumulate in marine bivalves through their filter-feeding behavior, covering mechanisms of ingestion, bioaccumulation, oxidative stress induction, immune disruption, and growth inhibition, with implications for food safety given widespread human consumption of bivalves.
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.
The impact of microplastics on bivalve mollusks: A bibliometric and scientific review
This review examines how microplastics affect bivalve shellfish like mussels, oysters, and clams, which are important both ecologically and as human food sources. Microplastics disrupt bivalve feeding, growth, reproduction, and immune function, and can also carry other toxic pollutants into their tissues. Since bivalves filter large volumes of water and are often eaten whole by humans, they represent a direct pathway for microplastic transfer from the ocean to our bodies.
The stealthy journey of nanoplastics in bivalves: accumulation dynamics and toxic burden
This review examined how bivalves' strong filter-feeding capacity leads to nanoplastic accumulation from surrounding water, covering accumulation dynamics, sub-lethal toxic effects across organ systems, and the implications for aquaculture food safety and bivalve-based environmental monitoring.
Exploring microplastics in commercial bivalve species and in bivalve aquaculture waters: Insights from the southern Pacific
Microplastics were detected in multiple commercially sold bivalve species (such as mussels and oysters) and in nearby inland and coastal waters. Because bivalves are widely eaten by humans, the findings raise direct concerns about microplastic dietary exposure through seafood consumption.
Influence of microplastics on freshwater bivalves (review)

Microplastics in commercial marine bivalves: Abundance, characterization and main effects of single and combined exposure
This review summarizes recent findings on microplastic contamination in commercially valuable marine bivalve species, documenting a wide variety of particle shapes, sizes, colors, and polymer types across multiple species. Researchers found that microplastic exposure, alone or combined with other pollutants, triggers immunological, physiological, behavioral, reproductive, genotoxic, and neurotoxic effects in these organisms. The study calls for harmonized research methodologies to enable better comparison of microplastic contamination levels across studies and regions.
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.
Microplastic pollution in commercially important edible marine bivalves: A comprehensive review
This review summarizes research on microplastic contamination in edible shellfish like mussels, clams, and oysters, which accumulate high levels of plastic particles in their tissues. Because bivalves are eaten whole including their digestive systems, they are a direct pathway for microplastics to enter the human body. While microplastics do not appear to kill shellfish outright, they can harm their immune systems and reproduction, potentially affecting both shellfish populations and human consumers.
Microplastics in Pnw, Bivalves, and the Impact on Oceanic Ecosystems and Human Health
This review discusses how microplastics accumulate in bivalves such as oysters and mussels in Pacific Northwest coastal waters, how they move up the food chain, and why seafood consumers in the region may face elevated exposure risks. The paper synthesizes the threat to both marine ecosystem stability and human health from microplastic bioaccumulation in commercially important shellfish.
Microplastics in coastal and marine environments: A critical issue of plastic pollution on marine organisms, seafood contaminations, and human health implications
This review highlights the serious threat microplastics pose to marine life and the millions of people who depend on seafood as a primary protein source. Marine organisms, especially filter-feeders like oysters and mussels, accumulate microplastics that can cause tissue damage, oxidative stress, immune changes, and behavioral problems. Since these shellfish are often eaten raw, any toxins they accumulate -- including microplastics -- pass directly to humans.
Direct and indirect effects of microplastics on bivalves, with a focus on edible species: A mini-review
This mini-review examined direct and indirect pathways by which microplastics affect bivalves including mussels, oysters, and clams, finding evidence that microplastics impair physiology, alter immune responses, and act as vectors for chemical pollutants. The authors highlight microplastics as an emerging threat to bivalve populations and seafood safety.
Presence of microplastics in six bivalve species (Mollusca, Bivalvia) commercially exploited at the Pacific coast of Costa Rica, Central America
Researchers found microplastics in all six commercially exploited bivalve species sampled from the Pacific coast of Costa Rica, with prevalence ranging from 74% to 100% across species, raising concerns about human exposure through seafood consumption in Central American coastal communities.
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.
Abundance, composition, and distribution of microplastics in intertidal sediment and soft tissues of four species of Bivalvia from Southeast Brazilian urban beaches
Researchers found 100% microplastic contamination in intertidal sediments and four bivalve species from urbanized Brazilian beaches, identifying polypropylene, polyethylene, and PET polymers in organisms commonly consumed by humans.
Occurrence and pathways of microplastics, quantification protocol and adverseeffects of microplastics towards freshwater and seawater biota
This review examines the occurrence, pathways, and adverse effects of microplastics on freshwater and marine organisms, highlighting how these particles can enter the food chain through seafood consumption. The study suggests that microplastic ingestion causes health hazards in aquatic animals and points to gaps in understanding how microplastics affect human health along the food supply chain.
Elucidating the consequences of the co-exposure of microplastics jointly to other pollutants in bivalves: A review
This review examines studies on the combined effects of microplastics and other pollutants in bivalves, finding that co-exposure often modifies individual toxicant effects and highlighting bivalves as important sentinel species for monitoring complex environmental contamination.
Microplastics as contaminants in commercially important seafood species
This review summarizes evidence that microplastic ingestion is widespread in commercially important seafood species including mollusks, crustaceans, and fish. Evidence indicates that microplastics can affect physiology, reproductive success, and survival in marine organisms, and may also act as vectors for chemical pollutants. The study highlights the potential for human exposure to microplastics through seafood consumption, though the full health implications remain to be determined.
Effects of microplastics on bivalves: Are experimental settings reflecting conditions in the field?
A critical comparison of experimental microplastic studies on bivalves found that most laboratory studies used particle concentrations far exceeding environmental levels and polymer types that differ from field observations, concluding that many reported toxic effects may not be ecologically relevant and calling for environmentally realistic experimental designs.

Microplastic contamination in commercially important bivalves from the southwest coast of India
Microplastics were detected in water and three commercially important bivalve species along the southwest coast of India, with concentrations varying by species and collection site. The presence of plastic particles in filter-feeding shellfish intended for human consumption raises concerns about dietary exposure.
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. While most countries showed relatively low pollution levels, the chemical composition of the microplastics found in bivalves varied widely, with some polymers posing greater health concerns than others. The study estimates that regular consumption of contaminated bivalves could represent a meaningful pathway for human microplastic exposure.
Characteristics of Suspended Particulate Matter, Benthic Environmental Factors, and Their Relationship to Bivalves
Despite its title referencing microplastics, this is primarily a review of suspended particulate matter (SPM) in coastal marine environments and how it affects bivalve shellfish populations — not a study of microplastic pollution or health effects per se. The paper briefly mentions that microplastic characteristics are an area needing more research within the SPM literature, but its core subject is the ecology of bivalves and particle dynamics. It is only tangentially relevant to microplastics science.
