This review examines microplastic contamination in coastal and marine environments, focusing on bivalves as sentinel organisms due to their filter-feeding behavior and widespread use as human food, synthesizing evidence on physiological damage across aquatic species and ecological risks from plastic particle transfer through food chains.
Monitoring water contamination through shellfish: A systematic review of biomarkers, species selection, and host response.
Across 20 studies spanning 14 countries, shellfish proved highly sensitive to minor environmental changes, with 26 species and 35 effect biomarkers identified, supporting their use as reliable bioindicators of water quality, though standardized monitoring protocols are still needed.
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.
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 stress-immunity axis in shellfish.
This review examines the stress-immunity relationship in shellfish, covering how environmental stressors — including chemical contaminants like microplastics — activate immune responses and affect shellfish health. Since shellfish are consumed by humans and accumulate microplastics from the water they filter, understanding how plastic pollution stresses these animals is important for seafood safety.
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.
Progress on the Effects of Microplastics on Aquatic Crustaceans: A Review
This review examined the effects of microplastics on aquatic crustaceans, finding that microplastics negatively affect life history, behavior, and physiological functions including oxidative stress, immune responses, and reproductive output across multiple species.
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 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.
Microplastic in bivalves of an urbanized Brazilian estuary: Human modification, population density and vegetation influence
Researchers measured microplastic contamination in oysters, clams, and mussels from a heavily urbanized estuary in Brazil, finding that industrial and port activities were stronger predictors of contamination than population density. Clams accumulated the most microplastics, and the study highlights how shellfish from polluted coastal areas can serve as indicators of the microplastic levels humans may be exposed to through seafood.
Microplastics in bivalves and their habitat in relation to shellfish aquaculture proximity in coastal British Columbia, Canada
Researchers compared microplastic concentrations in Manila clams and Pacific oysters grown at commercial shellfish aquaculture sites versus reference beaches in coastal British Columbia, finding that proximity to aquaculture operations influenced microplastic levels in both bivalves and surrounding sediments.
The Presence of Microplastics in Shellfish: A Review
This literature review synthesizes studies on microplastic presence in shellfish across global aquaculture and wild harvest settings, finding widespread contamination across species and highlighting ingestion during filter feeding as the dominant uptake route.
The physiological response of the clam Ruditapes philippinarum and scallop Chlamys farreri to varied concentrations of microplastics exposure
Researchers exposed two types of shellfish (clams and scallops) to polyethylene and PET microplastics and found that both species accumulated the particles in their digestive glands and gills. The exposure caused oxidative stress, disrupted energy and fat metabolism, and damaged tissue, with PET generally being more toxic than polyethylene. Since these are commonly eaten shellfish, the findings raise concerns about microplastic contamination affecting the safety of seafood for human consumers.
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.
Microplastics\nAffect the Ecological Functioning of\nan Important Biogenic Habitat
This study exposed intact sediment cores containing oysters and mussels to microplastics and found significant changes in the diversity and functioning of the bivalve-dominated community, including reduced biodiversity and altered nutrient cycling. The findings show that microplastics affect not just individual animals but entire benthic ecosystem functions important for water quality and marine food production.
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.
Effects of microplastics on physiological performance of marine bivalves, potential impacts, and enlightening the future based on a comparative study
This review examines the effects of microplastics and their chemical additives on the physiology of marine bivalves such as mussels and oysters, including impacts on feeding, reproduction, immunity, and gene expression. Researchers identified significant gaps in the literature, particularly regarding the combined effects of microplastics with other environmental stressors. The study highlights that while individual studies show varied results, the cumulative evidence suggests microplastic exposure can alter key biological functions in these ecologically important organisms.
From the raw bar to the bench: Bivalves as models for human health.
This review explores how bivalves such as oysters, mussels, and clams are used as model organisms for biological and ecological research, including their roles as biomonitors for pollution. The paper highlights how the genomic tools now available for studying bivalves are advancing understanding of their responses to environmental stressors including microplastic contamination.
Microplastics can aggravate the impact of ocean acidification on the health of mussels: Insights from physiological performance, immunity and byssus properties
Researchers found that the combination of ocean acidification and microplastic exposure weakened mussel immune systems, reduced feeding performance, and degraded the quality of byssus threads used for attachment. The study suggests that co-occurring ocean acidification and microplastic pollution could increase the vulnerability of bivalves to disease and dislodgement, threatening their survival in future marine environments.
Unraveling the interplay between environmental microplastics and salinity stress on Mytilus galloprovincialis larval development: A holistic exploration
Researchers studied how environmental microplastics and increased salinity together affect the early development of Mediterranean mussel larvae. The combination caused larval deformities, developmental problems, and changes in gene activity related to shell formation, stress response, and cell damage. These findings are concerning because climate change is altering ocean salinity in coastal areas where microplastic pollution is also heavy, and mussels are a food source that could pass accumulated microplastics to humans.
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.
