ClearDistribution of microplastics in surface water from Saigon River to Can Gio Sea
Researchers found widespread microplastic contamination in surface water samples from the Saigon River and Can Gio Sea in Vietnam, with concentrations and particle types shifting from river to coastal environments, reflecting the transport of land-based plastic pollution into marine systems.
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.

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.
Microplastic abundance and characteristics in seawater and inter-tidal sediments of the Tokin Bay Coast (North Vietnam)
This study characterized microplastic abundance and properties in seawater and intertidal sediments along the northern coast of Vietnam, providing some of the first systematic microplastic data for this developing country.

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 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.
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.
Current Plastic Waste Status and Its Leakage at Tam Giang–Cau Hai Lagoon System in Central Vietnam
Researchers quantified the annual leakage of plastic waste into the Tam Giang-Cau Hai lagoon system in central Vietnam by surveying surrounding urban and rural areas and applying a waste flow diagram model, estimating substantial annual plastic input to this coastal lagoon. The findings highlight the link between inadequate solid waste management and plastic contamination of aquatic ecosystems.
The combination of detection and simulation for the distribution and sourcing of microplastics in Shing Mun River estuary, Hong Kong
Researchers combined field sampling with hydrodynamic computer modelling to trace the sources and movement of microplastics in a Hong Kong river estuary, finding polyethylene was the dominant polymer type and that tidal conditions strongly influenced where plastics accumulated in water, sediment, and oysters. The combined detection-simulation approach offers a more complete picture of microplastic sources and transport than sampling alone, which is important for managing contamination in estuaries used for aquaculture.
Modeling the fate of microplastics in the Sengkarang Estuary, Pekalongan City, Central Java, Indonesia
Researchers measured microplastic concentrations in water and sediment at the mouth of the Sengkarang River in Indonesia and built a hydrodynamic model to track how tidal currents, wind, and river flow distribute the particles. Microplastics were highest in coastal waters and mangrove sediments, with tides and currents driving horizontal transport and concentrating particles in biologically sensitive habitats. The modeling approach offers a practical framework for predicting where microplastics accumulate and informing pollution management in river-to-sea systems.
Comparison of Microplastic Pollution in Beach Sediment and Seawater at UNESCO Can Gio Mangrove Biosphere Reserve
Microplastic concentrations in beach sand and seawater were compared across sites in the UNESCO Can Gio Mangrove Biosphere Reserve in Vietnam, with higher concentrations in sediments near boat traffic corridors and tourist areas, confirming that even protected biosphere reserves are contaminated and that local human activity drives spatial distribution patterns.
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.
Time-series of shoreline marine debris highlights impact of urbanization on coastal pollution pathways, Nha Trang, Vietnam.
A time-series analysis of shoreline marine debris in Nha Trang, Vietnam, revealed that urbanization drives increased coastal plastic pollution by altering land-based discharge pathways. The study documented how shoreline debris levels fluctuated seasonally and with rainfall events, providing insights for pollution management in developing coastal cities.

The study provides a modeling framework for understanding microplastic distribution in Indonesian coastal waters, which receive high plastic inputs from land.
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.
