ClearOccurrence 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.
Spatial and seasonal abundance and characteristics of microplastics along the Red River to the Gulf of Tonkin, Vietnam
Researchers surveyed microplastic contamination along the entire Red River from Hanoi to the Ba Lat estuary in Vietnam, sampling during both dry and rainy seasons. They found microplastics in all water and sediment samples, with fibers being the dominant shape and polyethylene, polypropylene, and PET the most common polymers. Microplastic levels were generally higher in sediment during the dry season, suggesting seasonal hydrology plays an important role in how plastics accumulate in river systems.

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
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.
Distribution 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.
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.
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.
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.
Microplastics pollution in selected rivers from Southeast Asia
Researchers surveyed microplastic pollution in rivers across Southeast Asia, a region with high plastic waste discharge but limited monitoring data, documenting the distribution and characteristics of microplastics in these understudied waterways.
Macroplastic and microplastic contamination assessment of a tropical river (Saigon River, Vietnam) transversed by a developing megacity
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.
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. The results document significant contamination in abiotic marine compartments of a rapidly industrializing coastal region.
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.

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.
Presence of Microplastic in Bottom Sediments of the Bach Hac River in Phu Tho Province, Vietnam
Microplastic contamination was documented in bottom sediments of the Bach Hac River in Phu Tho Province, Vietnam, with rivers identified as primary pathways transporting land-based MPs to the ocean. The study found that river sediments act as significant reservoirs for MP accumulation in upstream freshwater systems.

Classification of microplastic characteristics in surface water and sediments in the lower Mekong river (Vietnam) in the dry season
Researchers analyzed microplastic distribution and polymer composition at 17 locations along the Mekong River in Vietnam during the April 2024 dry season, collecting samples from both surface water and riverbed sediments and characterizing them by optical microscopy and FTIR spectroscopy. They found that microplastic densities were higher in more urbanized areas and were influenced by geographical location, transportation activities, population density, and local hydrological characteristics.
The occurrence and abundance of microplastics in surface water and sediment of the West River downstream, in the south of China
Researchers surveyed microplastic contamination in surface water and sediment of the West River downstream in southern China. They found microplastics in all samples, with concentrations ranging widely and fibers being the dominant shape. The study suggests that the downstream section of the West River serves as both a conduit and accumulation zone for microplastic pollution heading toward coastal waters.
Baseline concentration of microplastics in surface water and sediment of the northern branches of the Mekong River Delta, Vietnam
Researchers measured baseline microplastic concentrations in surface water and sediment along the Tien River and its distributaries in Vietnam's Mekong River Delta.
