ClearMicroplastics ingestions by wild and aquaculture marine bivalves: A systematic review on field investigation study
This systematic review of 33 studies found that shellfish like mussels, oysters, and clams from both wild and farmed sources contain microplastics. Since many people eat these shellfish whole, including their digestive systems, this represents a direct pathway for microplastic ingestion by humans.
A systematic review on the prevalence and concentration of MPs in mussels
This systematic review examines how common microplastics are in mussels, a popular seafood. Since mussels filter large volumes of water, they tend to accumulate microplastics, which means people who eat them may be exposed to these particles through their diet.
Unveiling 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.
Microplastic Pollution in Green Shells in Aquatic Ecosystems: A Literature Review of Determinant Factors and Management
This literature review synthesized 35 studies on microplastic contamination in green mussels (a widely consumed shellfish), finding that fibers under 1 mm were the most common form and that both human and industrial activities drive contamination levels. Because mussels filter large volumes of water, they concentrate microplastics from their surroundings and pass them on to people who eat them, making shellfish a key pathway for human dietary exposure.
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.
Microplastics in Fish and Seafood Species
This chapter reviews microplastic contamination in fish and seafood species, including how plastics enter seafood through wild capture and aquaculture pathways. Because seafood is widely consumed globally, microplastics in fish and shellfish represent a direct route of human dietary exposure.
Microplastics in global bivalve mollusks: A call for protocol standardization
Researchers reviewed 61 studies on microplastic contamination in bivalve mollusks worldwide, finding that these filter-feeding shellfish consistently contain microplastics regardless of location. The study found significant differences in contamination levels between bivalve families based on their habitats, suggesting that both water-dwelling and sediment-dwelling species can be used to monitor different types of microplastic pollution. The authors call for standardized sampling and analysis protocols to enable meaningful comparisons across future studies.
Microplastics contamination in molluscs from the northern part of the Persian Gulf
Researchers analyzed microplastic contamination in five species of mollusks from the northern Persian Gulf, including both gastropods and bivalves with different feeding strategies. They found microplastics in all species, with concentrations ranging from 0.2 to 21 particles per gram of soft tissue, and fibers were the most common type. The study indicates that microplastic contamination is widespread in Persian Gulf seafood and that filter-feeding organisms tend to accumulate more particles.
Microplastics and seafood: lower trophic organisms at highest risk of contamination
This systematic review summarizes existing research on microplastic contamination in commercially important seafood species. The findings show that organisms lower on the food chain, like shellfish and small fish, tend to accumulate the most microplastics. Since many people eat these organisms whole, including their digestive tracts, this represents a direct pathway for microplastics to enter the human diet.
Microplastics in Mollusks: Research Progress, Current Contamination Status, Analysis Approaches, and Future Perspectives
This review synthesizes 77 studies (2010-2021) on microplastic contamination in mollusks, finding that polypropylene, polystyrene, and polyethylene are the most common polymers in bivalves, with most particles under 500 µm in size and a positive correlation between seawater and mollusk MP abundance.
The Global Spread of Microplastics: Contamination in Mussels, Clams, and Crustaceans from World Markets
Researchers used a standardized method to analyze microplastic contamination in commercially sold clams, mussels, and crustacean shellfish from markets in Belgium, Croatia, Serbia, and South Korea. Microplastics were found in about 44% of the 190 samples, with less than one particle per individual on average, and crustacean shellfish had the lowest contamination per gram of edible tissue. The type of shellfish was a stronger predictor of contamination levels than geographic origin, and the data did not support bioaccumulation with animal size.
Microplastics in Fish and Shellfish – A Threat to Seafood Safety?
This review evaluated the current knowledge on microplastic contamination in fish and shellfish in relation to seafood safety. Researchers found that while microplastics are commonly detected in the gastrointestinal tracts of fish (which are typically not consumed), bivalves and small fish eaten whole may present a more direct route of human exposure, though the overall health risk from microplastics in seafood remains uncertain.
Microplastic Contamination and Exposure in Gastropods: A Literature Review
This literature review examined microplastic contamination in gastropod species across marine environments, assessing ingestion rates, particle types, and potential consequences for organism health and human seafood safety. The review found that gastropods consistently harbor microplastics, particularly fibers, and that bottom-dwelling species are among the most exposed due to sediment contact.
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.
Presence of Microplastics in Four Types of Shellfish Purchased at Fish Markets in Okayama City, Japan.
Scientists found microplastics in all four types of shellfish—oysters, clams, scallops, and mussels—purchased from fish markets in Okayama, Japan. The findings confirm that people who eat shellfish regularly ingest microplastics, raising questions about potential health impacts from this dietary exposure.
Dietary exposure to microplastic via shellfish and the importance of the edible shellfish tissue measurements
This study highlighted shellfish as a major source of human dietary exposure to micro- and nanoplastics, emphasizing the need for standardized analytical methods to enable comparable exposure assessments and risk characterizations across different countries and shellfish species.
Microplastics in the edible tissues of shellfishes sold for human consumption
Researchers analyzed the edible tissues of four shellfish species sold for human consumption and found microplastics present in all samples examined. Fibers were the most commonly detected particle type, with polymer identification confirming synthetic origins including polyethylene and polypropylene. The findings raise concerns about human dietary exposure to microplastics through commercially available seafood products.
Microplastics and their potential effects on the aquaculture systems: a critical review
This review examines the sources, distribution, and potential ecological effects of microplastics in aquaculture systems worldwide. Researchers found that microplastics enter aquaculture through feed, water intake, and atmospheric deposition, and can accumulate in farmed fish and shellfish tissues. The study highlights the need for monitoring programs and mitigation strategies to protect both aquaculture productivity and consumer safety from microplastic contamination.
Are bivalves a source of microplastics for humans? A case study in the Brazilian markets
Researchers found that all four species of bivalves sold in Brazilian markets contained microplastics, averaging 1.64 particles per gram, confirming that commercially sold shellfish are a source of microplastic exposure for consumers.
Microplastics in bivalves cultured for human consumption
Researchers examined two commercially farmed bivalve species, mussels and oysters, and found microplastics in the edible tissues of both. Mussels contained an average of 0.36 particles per gram of tissue, while oysters had 0.47 particles per gram. Since these shellfish are consumed whole without removing the gut, the study suggests they represent a direct pathway for human ingestion of microplastics.
Microplastics in commercial bivalves from China
Researchers analyzed microplastics in commercially sold bivalves from China, finding contamination across multiple species and geographic origins, with implications for human dietary microplastic exposure through shellfish consumption.
Microplastics in mussels sampled from coastal waters and supermarkets in the United Kingdom
Researchers measured microplastic contamination in mussels from U.K. coastal waters and supermarkets and found anthropogenic debris in every sample tested. Wild mussels contained up to 2.9 debris items per gram of tissue, while supermarket mussels showed lower but still consistent contamination levels. The study confirms that microplastics are prevalent in commercially available shellfish, representing a direct pathway for human dietary exposure.
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.
