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 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.
Assessment and Analysis of Microplastics in Commercially Sold Bivalves from Los Baños, Laguna, and Lipa, Batangas, Philippines
Researchers extracted and characterized microplastics from three commercially sold bivalve species (green mussel, Manila clam, and freshwater clam) purchased at Philippine markets, finding contamination ranging from 0.52 to 2.94 microplastic particles per gram fresh weight with fibers being the most common type.
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.
Microplastic contamination in marine mussels from the Atlantic coast of North Portugal and human risk of microplastic intake through mussel consumption
Researchers analyzed wild mussels from Portugal's Atlantic coast and found microplastics in all samples, with an average of about 1.6 particles per gram of mussel tissue. Based on typical Portuguese seafood consumption patterns, the estimated annual human intake of microplastics from mussels alone was calculated, highlighting that regular shellfish consumers face meaningful microplastic exposure through their diet.
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.
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.
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.
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.
Preliminary survey on the occurrence of microplastics in bivalve mollusks marketed in Apulian fish markets
Researchers surveyed mussels and oysters sold at fish markets in the Apulia region of Italy and found microplastics present in all samples tested. Mussels contained nearly three times more plastic debris than oysters, with small fragments under 500 micrometers being the most common. The findings raise food safety concerns because these shellfish are typically consumed whole, meaning all ingested microplastics are passed directly to the consumer.
Risk assessments of microplastic exposure in bivalves living in the coral reefs of Vietnam
Scientists measured microplastic contamination in shellfish living in coral reefs off the coast of Vietnam, finding an average of about 5.6 microplastic particles per individual. Polyethylene and polyamide fragments smaller than 100 micrometers were the most common types found. Since bivalves are filter feeders that people eat whole, these findings mean that consuming shellfish from these reefs involves direct ingestion of microplastics.
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.
Microplastic accumulation in bivalves collected from different coastal areas of Vietnam and an assessment of potential risks
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.
The occurrence and exposure of microplastics in bivalves from Qingdao, China
Researchers surveyed microplastic contamination in bivalves such as clams and mussels from the coast of Qingdao, China, and assessed human dietary exposure from eating them. They found an average of about one microplastic particle per individual shellfish, with fibers and rayon being the most common types. The study suggests that regular bivalve consumption in the region contributes to ongoing human microplastic exposure.
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.
Investigation on microplastics in some bivalves at Binh Dien Market in Hochiminh City, Vietnam
Microplastic fibers were found in all three bivalve species (blood cockles, clams, and razor clams) sold at a major wholesale seafood market in Ho Chi Minh City, Vietnam. Because these shellfish are consumed whole without processing that would remove gut contents, Vietnamese consumers are likely ingesting microplastics regularly through this food source — an understudied exposure pathway in Southeast Asia.
Microplastic on our plate, also in our shops…
Belgian researchers investigated whether microplastics are actually present in wild and farmed bivalves under field conditions, rather than only at the unrealistically high concentrations used in lab studies. They found microplastics in both wild and cultured mussels and oysters, providing the first direct evidence that these seafood species accumulate microplastics at environmentally relevant levels.
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.
