ClearA 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.
Occurrence and characteristics of microplastics in water and sediment samples along the red river to the gulf of tonkin, vietnam
Researchers surveyed microplastics in water and sediment along Vietnam's Red River from inland areas to the Gulf of Tonkin, documenting the types, sizes, and polymer compositions present. The findings show how a major river system acts as a pathway delivering plastic pollution from a densely populated landscape into coastal marine waters.

Researchers assessed macroplastic and microplastic contamination in a tropical river in Vietnam, finding elevated pollution levels linked to urban and agricultural land use along the waterway.
Distribution and Characteristics of Microplastics in Nhue - Day River Basin, Vietnam
Researchers investigated the distribution and characteristics of microplastics in the Nhue-Day River Basin in Vietnam, finding that microplastic abundance varies with seasonal changes and anthropogenic activities, posing threats to the ecosystem and the roughly 12 million people who depend on this river.
Occurrence and characteristics of microplastics in water and sediment samples along the red river to the gulf of tonkin, vietnam
This study characterized the occurrence and properties of microplastics in water and sediment samples along the Red River from inland Vietnam to the Gulf of Tonkin, mapping contamination levels across a major river system draining into the South China Sea. The findings help establish the scale of plastic inputs from Southeast Asian river systems, which are among the world's largest contributors to ocean plastic pollution.
Nghiên cứu mức độ ô nhiễm vi nhựa trong nước và trầm tích sông Sài Gòn–Đồng Nai
This Vietnamese-language study investigated microplastic pollution levels in water and sediments of the Saigon-Dong Nai River system. River systems like these are major transport pathways for microplastics from land-based sources into the ocean.
Sources of microplastic pollution in the Saigon-Dong Nai rivers, potential risks affecting human health and recommendations for mitigation solutions
Sampling of the Saigon-Dong Nai river system in Vietnam detected microplastic fragments, films, and fibres at concentrations of up to 715,000 particles per cubic metre, primarily sourced from urban runoff, wastewater, and industrial discharge. Because these rivers supply drinking water and support subsistence fishing for millions of people, the findings highlight a significant and largely unquantified human exposure pathway to microplastics in a rapidly urbanising region.
Distribution and characteristics of microplastics in surface water at some beaches in Thanh Hoa province, Viet Nam
Researchers characterized microplastic density, shape, size, and color in surface water at three beaches in Thanh Hoa province, Vietnam, finding high microplastic concentrations in this coastal marine environment. The study assessed microplastic exposure risks in a region where contamination can enter the food chain through aquatic organisms.
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. Highly populated cities like Hanoi and Ho Chi Minh City show the highest levels, with plastics entering water through agricultural runoff, textile production, and consumer products. The contamination poses health risks to millions of people through drinking water and seafood consumption.
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.
Characteristics of Microplastics and Their Affiliated PAHs in Surface Water in Ho Chi Minh City, Vietnam
Researchers characterized microplastics and associated polycyclic aromatic hydrocarbons (PAHs) in surface water across canals, the Saigon River, and coastal waters in Ho Chi Minh City, Vietnam, finding microplastics at all sites with the highest concentrations in urban canals and detecting co-occurring PAH 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.
Abundance and variation of microplastics between seasons in a tropical estuary: The case of Can Gio estuary, Vietnam
Researchers assessed seasonal variation in microplastic abundance and characteristics in the Can Gio estuary, Vietnam, across wet and dry seasons. Microplastic concentrations were higher during the wet season, with seasonal plastic transport linked to river discharge and rainfall-driven inputs from upstream urban sources.
Distribution of Microplastics in Beach Sand on the Can Gio Coast, Ho Chi Minh City, Vietnam
Researchers conducted the first survey of microplastic distribution in beach sands along the Can Gio Coast in Ho Chi Minh City, Vietnam, finding plastics at all five sites with abundance and composition varying by proximity to urban activity and depth within the sand profile.
Distribution of Microplastics in the Beach Indicating Anthropogenic Sediments: Case Study in Can Gio HCM City, Vietnam
Researchers characterised microplastics in coastal sediments of Can Gio, Ho Chi Minh City, Vietnam across dry and rainy seasons, examining characteristics, composition, size, shape, and distribution through boreholes and excavations at identified cross-sections.
Anthropogenic particle abundance and characteristics in seawater and intertidal sediments of the Tonkin Bay Coast (North Vietnam)
Researchers measured microplastic contamination in seawater and intertidal sediments at four sites along the northern Vietnam coast, finding fiber particles as the dominant type in both compartments. Higher microplastic levels were recorded during the rainy season, suggesting rivers are a primary transport route carrying plastic from inland sources to the sea. The study provides rare baseline data for a developing-country coastal zone and emphasizes that even smaller polymer fragments below the measured size range likely represent a significant unquantified hazard.
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.
