Researchers analyzed microplastic accumulation in five common bivalve species collected from aquaculture areas along the coast of Vietnam, finding microplastics in all samples with an average of about 10.84 items per individual. Fibers were the most common shape, concentrated in gills and digestive glands, and a risk assessment suggested potential implications for human health through seafood consumption.
Microplastic prevalence, diversity and characteristics in commercially important edible bivalves and gastropods in relation to environmental matrices
Researchers assessed microplastic abundance and characteristics in the tissues of commercially important bivalves and gastropods from the southwest coast of India, finding MPs across all five species examined and raising concerns about seafood safety.
Microplastics in Pacific Northwest Bivalves: Ecological Prevalence, Harvester-Consumer Exposure, and Aquarium Exhibit Outcomes
Researchers quantified microplastics in Pacific oysters and razor clams from 15 coastal sites in Oregon, finding widespread contamination across the Pacific Northwest coast. The study also assessed exposure risks to seafood harvesters and consumers, contributing to understanding of how coastal plastic pollution reaches human food supplies.
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.
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.

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 contamination in bivalves from the Daya Bay: Species variability and spatio-temporal distribution and human health risks
Researchers assessed microplastic contamination in six species of bivalves from Daya Bay, China, finding microplastics present in 87 to 93% of individuals sampled. Sediment-dwelling bivalves had higher microplastic levels than water-dwelling species, and the types of microplastics found in the shellfish matched those in the surrounding seawater and sediment. A risk assessment based on polymer hazard levels indicated that microplastic contamination in these bivalves may pose health risks to humans who consume them as seafood.
A systematic review on microplastic contamination in marine Crustacea and Mollusca of Asia: Current scenario, concentration, characterization, polymeric risk assessment, and future Prospectives
This systematic review documented microplastic contamination in shellfish and crustaceans across Asia, finding 79 species affected. Since these seafood species are widely consumed, the presence of microplastics — especially polyethylene and polypropylene — in their tissues represents a direct route of human exposure through diet.
An examination of the occurrence and potential risks of microplastics across various shellfish
Researchers compared microplastic contamination levels in commercial shellfish from northern (Qingdao) and southern (Xiamen) China, finding microplastics in 70-100% of samples. The study assessed potential human health risks from consuming contaminated shellfish, with microplastic abundances varying across species and geographic locations.
Microplastic abundance and characteristics in bivalves from Tam Giang-Cau Hai and O Loan Lagoons, coastal regions in Central Vietnam: Implication on human health
Researchers found microplastics in four types of commonly eaten shellfish from coastal lagoons in Central Vietnam, with an average of 0.3 to 0.9 particles per gram of tissue. Fibers were the most common shape, and the estimated weekly human intake from eating these shellfish ranged from about 56 to 486 particles. The study highlights that regular seafood consumption in coastal communities provides a direct route for microplastic exposure in the human diet.
ABUNDANCE AND CHARACTERISTICS OF MICROPLASTICS IN MARKET BIVALVE Aulacomya Atra (MYTILIDAE: BIVALVIA)
Microplastics were detected in the commercial bivalve Aulacomya atra sold at fisheries markets in three Peruvian provinces, with mean contamination levels and polymer types characterized, highlighting shellfish as a significant route for human microplastic ingestion through seafood consumption.
Occurrence, sources and potential human health risk of microplastics in seafood species
Researchers measured microplastic occurrence in seafood products available in local markets, identifying plastics in multiple species including fish, shrimp, and bivalves, and estimated potential human dietary intake based on consumption data. The study found that seafood lovers could ingest thousands of microplastic particles per year through regular consumption, with shellfish representing the highest per-serving exposure.
Concentration of microplastics in bivalves of the environment: a systematic review
Microplastics were found in bivalves across 70 species in 36 countries, with mussels (Mytilus spp.) and oysters (Crassostrea spp.) most studied, but inconsistent digestion and identification methodologies make meaningful cross-study comparisons of contamination levels difficult.

A year-long monitorization of microplastic pollution in a bivalve aquaculture located at a coastal lagoon from Portugal
Researchers conducted a year-long quarterly monitoring study of microplastic contamination in Crassostrea gigas (diploid and triploid) and Ruditapes philippinarum bivalves from a Portuguese coastal lagoon aquaculture, alongside monthly water and sediment sampling. Microplastics were detected in every environmental matrix and in all tissue types examined, including muscle, digestive gland, gills, and visceral mass, demonstrating persistent contamination throughout the aquaculture system.
Microplastic concentrations in two Oregon bivalve species: Spatial, temporal, and species variability
Researchers measured microplastic contamination in Pacific oysters and Pacific razor clams from 15 sites along the Oregon coast. They found microplastics in organisms from all sites, with whole oysters averaging about 11 pieces per individual, mostly fibers. This is the first study to document microplastics in Pacific razor clams and provides valuable coast-wide baseline data for comparing contamination across species, seasons, and locations.
Microplastics in four bivalve species and basis for using bivalves as bioindicators of microplastic pollution
Researchers found microplastics in 80% of shellfish samples (scallops, mussels, oysters, and clams) collected across four seasons in Qingdao, China. PVC and rayon fibers were the most common plastic types, with different shellfish species accumulating different sizes and types of particles. Since these shellfish are commonly eaten by people, the findings highlight a direct route for microplastics to enter the human diet through seafood.
