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.
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.
A review on microplastics in bivalves: analysis, quantification, and effects
This review synthesized 56 studies on microplastic contamination and effects in bivalves, covering analysis methods, quantification approaches, and biological impacts. The authors found wide variation in reported contamination levels due to methodological differences, and concluded that standardized protocols are urgently needed to assess the food safety and ecological risks of microplastic-contaminated 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.
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.
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.
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.
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.
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.
Bivalve Impacts in Freshwater and Marine Ecosystems
This review examines the ecological roles of bivalve molluscs in both freshwater and marine ecosystems, including their contributions to nutrient cycling, habitat creation, food web dynamics, and water filtration. The study highlights that bivalves are important ecosystem engineers whose filter-feeding behavior makes them particularly relevant for understanding microplastic uptake and transport in aquatic environments.
Accumulation of microplastics in the bivalve mollusc Unio tumidus under experimental and field exposures
Researchers found that the freshwater bivalve Unio tumidus accumulates microplastics in its tissues under both laboratory and field conditions, with accumulation rates dependent on particle concentration and exposure duration, confirming this species as a viable biomonitor for freshwater MP pollution.
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.
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.
An overview of the internalization and effects of microplastics and nanoplastics as pollutants of emerging concern in bivalves
This review examines how bivalves such as mussels and oysters take up, retain, and are affected by microplastics and nanoplastics. Researchers summarized findings on particle characteristics that influence toxicity, including size, shape, density, and the ability to carry other pollutants. The study highlights that while significant progress has been made using bivalves as bioindicators of plastic pollution, major knowledge gaps remain in understanding the full scope of these impacts.
Mikroplastens intåg i den limnologiska miljön - Allmän dammussla (Anodonta anatina) innehåller mikroplast
This Swedish study exposed freshwater mussels (Anodonta anatina) to microplastics and examined uptake and potential health effects, finding that mussels ingest microplastics and that higher exposures affected their physiology. The study contributes to understanding microplastic impacts on freshwater bivalves that are important for ecosystem function and serve as indicators of water quality.
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.

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.
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.
