ClearEvaluation of microplastic bioaccumulation capacity of mussel (Perna viridis) and surrounding environment in the North coast of Vietnam
Researchers measured microplastic contamination in green mussels, seawater, and beach sediment along the northern coast of Vietnam. Mussels contained an average of about 25 microplastic pieces per individual, while beach sediments had concentrations around 4,800 pieces per kilogram. PET was the most common polymer type, and the study shows that Vietnamese coastal waters and seafood carry meaningful levels of microplastic contamination.
Contamination of microplastic in bivalve: first evaluation in 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 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.
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.
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.
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.
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.
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.
Assessment of microplastic contamination in some marine species collected in Ba Ria – Vung Tau province
This study documented microplastic contamination in four commercially important marine species — oysters, green mussels, mullet, and tonguefish — from aquaculture and fishing areas in Ba Ria-Vung Tau Province, Vietnam. Microplastics were found in 100% of samples, with oysters having the highest concentrations. Because these species are widely consumed, the findings highlight a direct pathway for microplastic ingestion by humans via seafood and underscore the need for monitoring in Vietnamese coastal waters.
