Assessment of potential ecological risk for microplastics in freshwater ecosystems
Researchers assessed the ecological risk of microplastics across freshwater ecosystems worldwide, including rivers and lakes in China, Vietnam, Europe, and South America. While one risk method showed negligible danger, more comprehensive assessment approaches revealed extreme ecological threats at every location studied, suggesting that microplastic pollution in freshwater may be more serious than previously thought.

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.
Microplastic Pollution in Surface Waters and Sediments of Urban Lake
This book chapter reviews microplastic pollution in urban lake surface waters and sediments, describing sources, distribution patterns, and the ecological consequences of MP accumulation in these widely used but understudied freshwater habitats.
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.
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.
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.
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.
Microplastic in Corbicula sp. collected from Ba Be Reservoir
Researchers sampled freshwater clams (Corbicula sp.) from Ba Be Reservoir in Vietnam, finding microplastics in all individuals at densities of 5–11 particles per animal, with fibers, polypropylene, and PET as the dominant types, establishing a baseline for this understudied region.
Distribution 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.
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.
Distribution, Sources, and Ecological Risk Assessment of Microplastics in the Lower Minjiang River

[Occurrence Characteristics of Microplastics in Baiyangdian Lake Water and Sediments].
This study measured microplastic abundance and characteristics in both the water and bottom sediments of Baiyangdian Lake in China, finding average concentrations of about 6,255 particles per cubic meter in surface water and 11,088 particles per kilogram in sediments. The dominant polymer in water was PET, while sediments were dominated by chlorinated polyethylene, and larger particles settled faster according to Stokes' law calculations. The results suggest textile washing wastewater and wear from boats and buildings are key local pollution sources, with important implications for understanding contamination of this important freshwater ecosystem.
