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.
Assessment of current water quality status in clam areas in Thai Binh Province and proposal for measures to improve efficiency
This study assessed water quality in clam farming areas in Thai Binh Province, Vietnam, monitoring multiple parameters to evaluate farming conditions. Water quality in shellfish farming areas is relevant to microplastic research, as clams accumulate microplastics and other contaminants from their surrounding water.
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.
Influences of anthropogenic activities on water quality in the Saigon River, Ho Chi Minh City
Researchers assessed water quality across agricultural, industrial, residential, and less-impacted zones of the Saigon River in Ho Chi Minh City, measuring physicochemical parameters, nutrients, heavy metals, and antibiotic residues across rainy and dry seasons. Higher turbidity and BOD5 levels were observed in the rainy season, highlighting the influence of land use and seasonal variation on river water quality.
Assessment of stream quality and health risks in Indonesian river systems: A social analysis and water quality index approach
Researchers assessed water quality in three Indonesian rivers used by local communities, finding microplastics — primarily polyethylene and polypropylene — alongside elevated levels of iron, lead, and manganese, with residents reporting rising rates of skin disease and diarrhea linked to polluted water use.
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.
Combined risks of microplastics, trace metals, and antimicrobial resistance in the Nhue–Day River Basin, Vietnam
Researchers investigated the Nhue-Day River basin in Vietnam — a heavily industrialized and agricultural watershed — and found microplastics across all sampled sites acting as carriers for trace metals like lead, chromium, and arsenic, with fishponds showing 6.5 times higher microplastic levels than rivers. Antibiotic resistance genes were also detected near industrial discharge points, though a direct link to microplastics was less clear. The study provides an important baseline for a region where contaminated water is used directly for irrigation and fish farming, raising food safety concerns.
Microplastics in the surface water of urban lakes in central Vietnam: Pollution level, characteristics, and ecological risk assessment
Researchers surveyed seven urban lakes in central Vietnam and found moderate levels of microplastic contamination, with concentrations varying between dry and wet seasons. Fibers were the most common type of microplastic found, primarily made of polypropylene and PET, and ecological risk assessments indicated low to moderate risk levels for the lake ecosystems.
Distribution, Characteristics, and Ecological Risk Assessment of Microplastics and Heavy Metals in Surface Water at Hoa Binh Reservoir
Researchers sampled surface water in Hoa Binh Reservoir, Vietnam, during rainy and dry seasons, finding microplastics at all sites with fiber-dominated assemblages, and documenting co-occurrence with heavy metals including chromium, manganese, and lead.
Risk levels of microplastic pollution in surface water and sediments at Ba Be Lake
Researchers assessed microplastic pollution in surface water and sediments of Ba Be Lake, Vietnam, documenting MP concentrations, polymer types, and spatial distribution to characterize contamination levels and ecological risk in this protected freshwater lake ecosystem.
Integrated assessment of the surface source of water supply according to environmental-risk indicators
Researchers assessed surface water quality and environmental health risks in the Dnipro Reservoir watershed using a four-stage risk assessment framework, identifying wastewater discharge, uncontrolled runoff, and bank erosion as major pollution sources. The study quantified health risks from multiple contaminants to support water supply management.
Characterization of Microplastics in Household Tap Water in Vietnam's Rural Areas: A Preliminary Study in the Red River Delta Region
Researchers conducted the first survey of microplastic contamination in household tap water in rural areas of Vietnam's Red River Delta. The study found an average of 6.8 microplastic particles per liter, mostly fragments and fibers smaller than 200 micrometers, with a polymer hazard index indicating high pollution risk levels across the sampled tap water.
Ecological risk assessment of microplastics and heavy metals in Northern Vietnam's estuarine sediments: A case study of Ba Lat and Bach Dang
Researchers assessed microplastic abundance and ecological risk alongside ten heavy metals in estuarine sediments from the Ba Lat and Bach Dang estuaries of northern Vietnam's Red-Thai Binh River system, finding co-contamination patterns that pose compounded ecological risks to these biodiverse coastal ecosystems.
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.
Water Pollution Index and Microplastic Ecological Risk in The North Coastal Area of Situbondo
Researchers assessed water quality and microplastic ecological risk across 15 locations along the northern coast of Situbondo, Indonesia, and found mild water pollution throughout the study area. Microplastics were found at all sampling sites, with industrial-adjacent areas and estuaries showing higher ecological risk than natural river locations. The study provides baseline data on the extent of microplastic contamination in an Indonesian coastal region and highlights the need for monitoring near industrial zones.
