Peculiarities of Microplastic Accumulation in Fish and Crustaceans of the Mekong Delta (Vietnam)
Summary
Researchers identified microplastic particles in the tissues of 11 out of 12 fish species and 6 crustacean species sampled from the Mekong Delta in Vietnam using hydrogen peroxide tissue digestion. Blue-violet fibers were the dominant plastic type found across both fish and crustacean taxa, adding to evidence of widespread microplastic contamination in Southeast Asian riverine biodiversity.
Plastic pollution of Asian rivers is one of the global problems of the region. Work was carried out to identify microplastic particles in the tissues of some species of hydrobionts from the Mekong Delta, one of the largest rivers in Southeast Asia. The method of tissue decomposition with 30% hydrogen peroxide was used. The presence of microplastic particles was revealed in 11 out of 12 fish species and in 6 crustaceans species. The dominant type of plastic in both fish and crustaceans was blue-violet fibers.

Peculiarities of Microplastic Accumulation in Fish and Crustaceans of the Mekong Delta (Vietnam)
Researchers found microplastic particles in nearly all fish and crustacean species sampled from the Mekong Delta in Vietnam, with blue-violet fibers being the most common type. The widespread contamination across 11 of 12 fish species and all 6 crustacean species tested highlights how deeply microplastics have penetrated even the food species of one of Southeast Asia's largest river systems, raising concerns for both ecosystem health and food safety for the millions of people who depend on the Mekong for protein.
Microplastic contamination in freshwater fish: first insights from the Mekong River in Nakhon Phanom Province, Thailand
Researchers found microplastics in 100% of 89 fish gastrointestinal tracts sampled from the Mekong River in Thailand, averaging 23.76 items per individual, with fragments being the dominant shape (83%), particles under 100 µm the most common size, and 17 polymer types identified across species.
Ingestion and accumulation of microplastics in small marine fish and potential human exposure: case study of Binh Dinh, Vietnam
Researchers investigated microplastic accumulation in five small marine fish species commonly consumed by coastal communities in Binh Dinh, Vietnam. They found microplastics present in fish from all sampling sites, with seasonal and species-level variation in contamination levels. The study estimates potential human dietary exposure to microplastics through fish consumption and raises food safety concerns for coastal populations relying on local seafood.
Occurrence and characterization of microplastic content in the digestive system of riverine fishes
Researchers found microplastics in 93.8% of riverine fish examined, with polystyrene, polyethylene, and nylon being the most common polymer types concentrated near urban and industrial areas, and small particles (0.025-1 mm) predominating across species.
Preliminary assessment of microplastic pollution in commercial freshwater fish species collected from four districts in Bac Ninh province
This study documented microplastic contamination in the gastrointestinal tracts of four commercially farmed freshwater fish species in Bac Ninh Province, Vietnam, finding microplastics in 100% of fish examined. Fibres were the dominant form and concentrations varied between fish species and collection sites. The results provide an early baseline for microplastic monitoring in Vietnamese freshwater aquaculture and highlight a potential route of human exposure through consumption of farmed fish.
