ClearDistribution of microplastics in surface water of tropical urban lakes: A case study in Ha Noi, Vietnam
Surface water surveys across three urban lakes in Hanoi found microplastics in all locations, with abundance highest in West Lake, which is surrounded by dense population, restaurants, and aquaculture activity. The findings confirm that urban lakes in developing Southeast Asian cities are significant microplastic repositories, with direct implications for the people who use these waters for recreation, fishing, and drinking water supply.
Microplastics in sediments from urban and suburban rivers: Influence of sediment properties
Researchers measured microplastic concentrations in sediments from 12 sites across three Vietnamese rivers in the Red River Delta during dry and rainy seasons, finding concentrations ranging from 1,600 to 94,300 items per kg dry weight. Fiber-dominated microplastic contamination was strongly influenced by sediment properties including grain size and organic carbon content.
Abundances and characteristics of sedimentary microplastics in the three main Vietnamese Rivers

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.

Characteristics and risks of microplastic contamination in aquaculture ponds near the Yangtze Estuary, China
Researchers measured microplastic contamination in aquaculture ponds near the Yangtze River in China, finding an average of 36 particles per liter in water and 272 particles per kilogram in sediment. Polyethylene was the most common plastic type, and crab and prawn ponds had higher contamination than fish ponds. Since farmed seafood is a major food source, this contamination could be a pathway for microplastics to reach human diets.
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.
Characteristics of Microplastics in Sediment at Danang Beaches - Vietnam
Researchers characterised microplastics in beach sediments at Danang, Vietnam, determining their abundance, morphology, colour, and polymer composition. The study found microplastic contamination at all sampled sites, identifying fibres and fragments as dominant forms and linking plastic sources to local tourism, fishing, and urban runoff.
Microplastics in fish culture ponds: abundance, characterization, and contamination risk assessment
Researchers surveyed five types of fish farming ponds in Bangladesh and found microplastics in all sediment and water samples, with higher contamination near industrial areas. The most common microplastics were small fragments and fibers made of polyethylene and polypropylene, likely originating from packaging waste and fishing gear. The findings raise concerns about microplastic contamination in farmed fish that are destined for human consumption.
Vertical distribution and sediment accumulation of microplastics in coastal aquaculture ponds of Kalanganyar Sidoarjo, East Java, Indonesia
Researchers evaluated the vertical distribution and sediment accumulation of microplastics in aquaculture ponds in Kalanganyar Sidoarjo, East Java, Indonesia, sampling water and sediment across inlet channels, pond interiors, and a nearby river. The study found microplastics throughout the water column and in sediments, with distribution patterns reflecting both hydrodynamic transport and local contamination sources.
Characteristics and ecological risks of microplastic contamination from aquaculture ponds located on South Yellow Sea Mudflat
Researchers characterized microplastic contamination across aquaculture ponds on the South Yellow Sea mudflat, finding concentrations of 32 items/L in water and 253 items/kg in sediment, with higher levels in crab and shrimp ponds compared to fish ponds. Ecological risk assessment revealed pollution load indices exceeding 1 and a polymer risk index corresponding to risk level III, driven primarily by the high hazard score of polyvinyl chloride.
Risk Assessment of Microplastic Exposure in the Marine Sediment of Southern Central Waters of Vietnam
Researchers collected sediment samples from 14 sites in southern central Vietnamese coastal waters and detected microplastics at all locations (100–1,350 MPs/kg), identifying fibers and fragments as the dominant forms and nine polymer types, providing the first microplastic baseline for this region.

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.
Preliminary Investigation of Microplastic Pollution in Agricultural Soil in Dong Anh District, Hanoi City
Agricultural soil samples from five sites in suburban Hanoi, Vietnam contained 494 to 1031 microplastic particles per kilogram of dry soil, with PET as the dominant polymer (38%) and fragments as the most common shape. The study provides baseline contamination data for a rapidly urbanizing agricultural region of Southeast Asia where plastic use and waste mismanagement are both growing. Documenting microplastic levels in food-producing soils is a critical first step for assessing dietary exposure risks for local populations.

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.
