ClearAbundance of Microplastics in Two Venus Clams (Meretrix lyrata and Paratapes undulatus) from Estuaries in Central Vietnam
Microplastics were found at 2.17-5.36 items per gram in two edible bivalve species from Da Nang estuaries in Vietnam, with fibres dominant at 300-1500 microns, and estimated consumer intake from clam consumption of approximately 2489 microplastic items per person per year.
Assessment of Microplastics Contamination in Commericial Clams in the Coastal Zone of Vietnam
Microplastic contamination was assessed in commercially harvested clams from aquaculture farms in coastal Vietnam, a country where microplastic impacts on aquaculture are poorly understood. Both vertebrates and invertebrates in coastal areas were found to ingest microplastics, raising concerns about food safety in Vietnamese seafood.
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.
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.
Microplastic contamination in Bivalves: An assessment of potential health risks to humans and bivalves in the Tam Giang Lagoon
Researchers analysed microplastic contamination in three bivalve species from Tam Giang Lagoon in Vietnam, finding 291 MP particles across 36 specimens, with clams showing the highest burden (67% of total MPs). The findings indicate significant human dietary MP exposure from lagoon bivalves and call for monitoring of this food source.
Potential risks of accumulated microplastics in shells and soft tissues of cultured hard clams (Meretrix taiwanica) and associated metals
Researchers found microplastics in both the shells and soft tissues of farmed hard clams in Taiwan, with small fibers being the most common type. The soft tissues showed higher potential ecological risk from microplastics than the shells, and the health risk from eating contaminated clams was greater for children than adults. While metal levels in the clams were within safe limits, the study highlights shellfish as another source of human microplastic exposure.
First report on microplastics in a freshwater clam, Corbicula baudoni, in Vietnam
Researchers conducted the first study of microplastic contamination in the freshwater clam Corbicula baudoni from the Mekong River Delta in Vietnam. They monitored both small and large clams monthly and found microplastics present in the organisms. The findings raise concerns about microplastic transfer through freshwater food chains and potential human exposure through shellfish consumption in the region.
Diversity and characteristics of microplastics in bivalves from Tam Giang Lagoon
This study found microplastics in all three bivalve species sampled from Vietnam's Tam Giang Lagoon—one of Southeast Asia's largest lagoon systems—with clams carrying the highest total proportion and green mussels showing the highest concentration per gram of tissue. Because bivalves are widely consumed in the region, their contamination represents a direct pathway for human microplastic ingestion.
Microplastics in mangroves with special reference to Asia: Occurrence, distribution, bioaccumulation and remediation options
This review examines microplastic contamination in Asian mangrove ecosystems, finding higher pollution levels near fishing, tourism, and industrial areas. Organisms throughout the mangrove food web, from shellfish to fish, accumulate microplastics based on their feeding habits and habitat. While mangrove plants can trap some microplastics in their roots, the widespread contamination of these coastal ecosystems raises concerns about the safety of seafood harvested from mangrove areas for human consumption.
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.
Preliminary determination of microplastics in bivalves collected from Phu Yen, central Viet Nam
Researchers conducted a preliminary determination of microplastics in four bivalve species from Phu Yen, central Vietnam, detecting MPs in clams, ark clams, oysters, and green mussels commonly consumed by local populations.
Microplastic in mangrove horn snail Telescopium telescopium (Linnaeus, 1758) at mangrove ecosystem, Rambut Island, Jakarta Bay, Indonesia
Researchers found high concentrations of microplastics inside horn snails from an Indonesian mangrove ecosystem, with film-type plastic dominating in both the animals and surrounding sediment. Mangrove-associated shellfish are important food sources for local communities, making microplastic contamination in these animals a potential human health concern.
Prevalence of microplastics in Peruvian mangrove sediments and edible mangrove species
Scientists found microplastics in sediment and two popular seafood species (black ark clams and mangrove crabs) from mangrove ecosystems in Peru. Both species contained microplastics, with crabs having slightly more than clams, and fibers were the most common type found. Since these are commonly eaten foods, the findings raise concerns about microplastic exposure through seafood in South American coastal communities.
Contamination of microplastics in mangrove sediment cores from Lach Huyen area, Hai Phong city, Vietnam
Microplastic concentrations in sediment cores from mangrove forests near a major Vietnamese port averaged over 1,300 particles per kilogram — substantially higher than comparable regions globally — with fibres comprising 80% of particles and concentrations decreasing with sediment depth, suggesting recent intensification of pollution. Mangrove sediments act as long-term plastic sinks, and the high fibre burden raises concern for the benthic organisms and communities that depend on these critical coastal ecosystems.
Assessment of microplastic presence in coastal environments and organisms of Da Nang, Vietnam
Researchers assessed microplastic contamination in seawater, sediments, and marine organisms along the coast of Da Nang, Vietnam. The study found microplastics in all sampled environments, with fibers being the most common shape and nylon the most prevalent polymer type. Benthic organisms like oysters and mussels contained significantly higher microplastic concentrations than fish, suggesting that habitat and feeding behavior influence uptake.
Microplastics in natural seafood of Vietnam and their potential exposure to consumers: A mini review
Researchers reviewed studies on microplastic contamination in seafood from Vietnam, finding plastic particles in 21 marine species including fish, shrimp, and shellfish, with fish carrying the highest loads. The findings highlight that consumers eating Vietnamese seafood regularly are ingesting microplastics, raising public health concerns about exposure through a major food source.
Microplastics contamination in molluscs from mangrove forest of Situbondo, Indonesia
Microplastics were found in all but one of 40 bivalve and gastropod molluscs sampled from a mangrove forest in Indonesia, with fibers being the dominant type and larger animals containing more particles. Mangrove ecosystems sit at the boundary between land and sea and are heavily used as nursery habitats, so microplastic contamination of molluscs there points to both direct harm to these organisms and potential risk to people who consume them.
Microplastic contamination in filter-feeding bivalves inhabiting the natural ecosystem of Da Nang Bay: An investigation of oysters (Ostrea rivularis) and green mussels (Perna viridis)
Researchers found microplastics in 100% of examined oysters and green mussels from Da Nang Bay, Vietnam, with average densities of 3.5 items per gram of tissue, exceeding average contamination levels seen in seafood across Asia. Mussels showed considerably higher MP accumulation than oysters, with black plastic particles under 0.5 mm in fibrous form being the dominant type found.
Depth Profiles of Microplastics in Sediment Cores from Two Mangrove Forests in Northern Vietnam
Microplastic contamination in sediment cores from two mangrove forests in northern Vietnam was analyzed by depth, finding concentrations ranging from 0 to 49 items per kg and providing a historical record of plastic pollution accumulation in these ecologically important coastal wetlands.
Charting the microplastic menace: A bibliometric analysis of pollution in Malaysian mangroves and polypropylene bioaccumulation assessment in Anadara granosa
Researchers surveyed microplastic contamination in Malaysian mangrove ecosystems and tested how a common shellfish species accumulates polypropylene particles. They found microplastics in all sediment and water samples, with the shellfish readily taking up fiber-shaped particles. The estimated dietary intake suggests that consumers of these shellfish could ingest hundreds of microplastic particles per year, highlighting food safety concerns.
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.
Spatial Distribution of Microplastic Contamination in Blood Clams (anadara Granosa) on the Jeneponto Coast, South Sulawesi
Researchers mapped the distribution of microplastic contamination inside blood clams (Anadara granosa) harvested along the Jeneponto coast of South Sulawesi, Indonesia. The highest microplastic levels were found in clams from mangrove ecosystems and residential waterways, while river areas showed the lowest contamination. Because blood clams are widely eaten as a daily food source, these findings raise direct concerns about microplastic ingestion by local populations.
Evaluation of the microplastics in bivalves and water column at Pantai Teluk Likas, North Borneo, Malaysia
Researchers found microplastics in all three species of shellfish and in the surrounding water at a popular beach in Sabah, Malaysia. One clam species contained over 113 microplastic particles per gram, primarily fibers made of common plastics like nylon and polypropylene. Since these shellfish are eaten by local communities, the contamination raises concerns about human exposure to microplastics through seafood consumption.
Microplastic contamination in edible clams from popular recreational clam-digging sites in Hong Kong and implications for human health
Researchers examined 249 wild clams from recreational digging sites in Hong Kong and found that over 56% contained microplastics, averaging about one particle per individual. Based on consumption patterns, they estimated that Hong Kong residents may ingest over 14,000 microplastic particles annually from wild clam consumption alone. A risk assessment using a polymer hazard index indicated a medium level of concern for human health.
