Ingestion and accumulation of microplastics in small marine fish and potential human exposure: case study of Binh Dinh, Vietnam
Researchers investigated microplastic accumulation in five small marine fish species commonly consumed by coastal communities in Binh Dinh, Vietnam. They found microplastics present in fish from all sampling sites, with seasonal and species-level variation in contamination levels. The study estimates potential human dietary exposure to microplastics through fish consumption and raises food safety concerns for coastal populations relying on local seafood.
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.
Baseline assessment of microplastic concentrations in marine and freshwater environments of a developing Southeast Asian country, Viet Nam
Researchers conducted the first baseline assessment of microplastic concentrations across marine and freshwater environments in Viet Nam, adapting sampling methods for developing-country conditions. They found microplastics present in all sampled water bodies, with concentrations comparable to those reported in more industrialized nations. The study establishes important reference data for tracking future pollution trends in Southeast Asian waterways.
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.
Risk of aquaculture-derived microplastics in aquaculture areas: An overlooked issue or a non-issue?
This review examines aquaculture-derived microplastics from degrading fishing nets and foam buoys, finding they represent a significant but overlooked source of marine microplastic pollution with distinct environmental consequences compared to other sources.
Abundances and characteristics of sedimentary microplastics in the three main Vietnamese Rivers
Researchers characterized the abundance, types, and distribution of microplastics in sediments of Vietnam's three major rivers, contextualizing findings within Vietnam's status as one of the world's top plastic waste-polluting countries with approximately 3.1 million metric tons of mismanaged plastic waste annually.
A preliminary assessment of microplastic occurrence and their potential risk as pollutant transport vectors: A case study in Phu Ly, Ha Nam, Vietnam
Researchers conducted a preliminary assessment of microplastic occurrence in Vietnam, identifying microplastics in environmental samples and raising concern about their role as vectors for co-transported pollutants in an undersampled region of Southeast Asia.
Identification and Quantification of Microplastics in Aquaculture Environment
This review covers high-efficiency analytical methods for identifying and quantifying microplastics in aquaculture environments, addressing the growing concern that plastic products widely used in aquaculture operations are an underreported source of microplastic contamination.
Riverine Microplastic Pollution in Vietnam: A Review of Current Scientific Knowledge and Legal Policies
This review summarizes current scientific knowledge and legal policies regarding microplastic pollution in Vietnam's rivers. Evidence indicates that microplastics are present in riverine surface water, sediments, and biota across Vietnam's canal and estuarine systems, with potential implications for human health through seafood consumption and drinking water.
Initial assessment of the presence of plastic waste in some coastal mangrove forests in Vietnam
A survey of coastal mangrove forests in Vietnam found significant plastic waste accumulation, raising concerns for marine biodiversity and the coastal communities that depend on healthy mangrove ecosystems.
Ecological risk assessment of microplastics and heavy metals in Northern Vietnam's estuarine sediments: A case study of Ba Lat and Bach Dang
Researchers assessed microplastic abundance and ecological risk alongside ten heavy metals in estuarine sediments from the Ba Lat and Bach Dang estuaries of northern Vietnam's Red-Thai Binh River system, finding co-contamination patterns that pose compounded ecological risks to these biodiverse 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.
A Review of Microplastics Pollution in the River Basin of Vietnam in Comparison with the World Context
This review examines microplastic pollution across Vietnam's river basins in the context of global patterns, finding significant contamination in surface water, sediments, aquatic organisms, and mangrove ecosystems — particularly in coastal urban areas — with concentrations in some urban rivers reaching 519,000 pieces/m³.
Plastic waste in sandy beaches and surface water in Thanh Hoa, Vietnam: abundance, characterization, and sources
Plastic waste surveys on three major beaches in Thanh Hoa, Vietnam documented abundant marine debris including microplastics, with quantities reflecting nearby anthropogenic activities and waste management gaps. The findings provide a baseline for coastal management and pollution control in the region.
Occurrence and Characteristics of Microplastics in Wild and Farmed Shrimps Collected from Cau Hai Lagoon, Central Vietnam
Researchers measured microplastic occurrence in the gastrointestinal tracts and tissues of four shrimp species (two wild, two farmed) from a Vietnamese lagoon, finding microplastics in all species and providing baseline data on seafood plastic contamination for this region.

Preliminary assessment of microplastic pollution in commercial freshwater fish species collected from four districts in Bac Ninh province
This study documented microplastic contamination in the gastrointestinal tracts of four commercially farmed freshwater fish species in Bac Ninh Province, Vietnam, finding microplastics in 100% of fish examined. Fibres were the dominant form and concentrations varied between fish species and collection sites. The results provide an early baseline for microplastic monitoring in Vietnamese freshwater aquaculture and highlight a potential route of human exposure through consumption of farmed fish.
Emergence of microplastics in the aquatic ecosystem and their potential effects on health risks: The insights into Vietnam
This review examines the growing microplastic contamination in Vietnam's waterways, where concentrations in surface water vary enormously depending on location.
