Researchers investigated the distribution and characteristics of microplastics in surface sediments across the Gulf of Thailand, finding an average abundance of 150.4 pieces/kg dry weight with fragment shapes dominating, and observed a correlation between sediment grain size and microplastic content. The results establish baseline contamination data for this Southeast Asian coastal region.
Assessment of microplastic abundance and characteristics in the coastal water of Hai Phong, Vietnam
Researchers assessed microplastic abundance and characteristics in coastal waters of Hai Phong, Vietnam, finding concentrations of 11.1 items per cubic meter in net samples and 1,515.4 items per cubic meter in bucket samples, with fibers accounting for more than 60% of the 2,659 particles identified.
The Distribution of Microplastics in Beach Sand in Tien Giang Province and Vung Tau City, Vietnam
Microplastics were found in beach sand samples from four sites in Tien Giang Province and Vung Tau City, Vietnam, with fragments being the most common type near estuaries. The study reveals that popular bathing beaches are hotspots for microplastic contamination, raising concerns for swimmers and seafood consumers.
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.
Assessment of microplastic presence in coastal environments and organisms of Da Nang, Vietnam
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.
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.
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 pollution in coastal surface seawater of Southern Vietnam

Abundance and variation of microplastics between seasons in a tropical estuary: The case of Can Gio estuary, Vietnam
Researchers assessed seasonal variation in microplastic abundance and characteristics in the Can Gio estuary, Vietnam, across wet and dry seasons. Microplastic concentrations were higher during the wet season, with seasonal plastic transport linked to river discharge and rainfall-driven inputs from upstream urban sources.
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.
