Assessment of microplastic abundance and characteristics in the coastal water of Hai Phong, Vietnam
Summary
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.
Microplastics (MPs) in marine environments are currently a source of concern worldwide because they are pollutants to marine organisms and ecosystems. Research on the distribution and characteristics of microplastics can help identify pollution levels or their effects on marine species. In this study, we collected samples from the coastal water of Hai Phong, one of northern Vietnam's most densely populated areas with several industrial, tourism, and aquaculture zones. The concentration of microplastics in the net was 11.1 ± 7.5 items/m3, and in the bucket was 1,515.4 ± 1,406.4 items/m3; of the 2,659 microplastics (items), 1,041 were fragments, and 1,618 were fibers, accounting for more than 60% of the total. Microplastics are primarily disseminated type fibers with a size of 2 mm, and most of which are made of polyethylene, polypropylene, and polystyrene. The results will serve as a basis for future research into microplastic features and their effects on the sedimentary environment and species in coastal areas of Hai Phong, Vietnam.

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.
Characteristics of microplastics in shoreline sediments from a tropical and urbanized beach (Da Nang, Vietnam)
Microplastic characterization of shoreline sediments at Da Nang beach, Vietnam found an average of 9,238 ± 2,097 items/kg, with synthetic fibers accounting for 99.2% of particles — predominantly blue and white — concentrated in the 0–5 cm surface layer and smaller than 500 µm.
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.
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.
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.
