Preliminary assessment of microplastic pollution in commercial freshwater fish species collected from four districts in Bac Ninh province
Summary
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.
Microplastics (MPs) are of emerging widespread concern, but amount of research done in freshwater environments and organisms is scarce compared to that in marine environments. Thus, the MPs identification in four freshwater fish at four districts of Bac Ninh province were documented, including common carp (Cyprynus carpio), grass carp (Ctenopharyngodon idella), tilapia (Oreochromis niloticus), and red-tilapia (Oreochromis sp.). MPs were found in the gastrointestinal tracts (GIT) of 100% of examined fish. MPs abundances have significant differences between all freshwater fish collected from ponds and local markets (except for red-tilapia), while no difference by individual of each species neither in pond nor in local markets. The median sizes of microplastics ranged from 1410 µm to 2706 µm. The MPs were dominated by purple in color (in pond with average 38%; in local market with average 33%). µ-FTIR analysis showed that polymers found in fish GIT mainly were polyethylene terephthalate, polyethylene, polypropylene and nylon. These results showed that the microplastics was widely ingested by freshwater fish and help to aware people which fish are more contaminated with MPs to human consumption in Bac Ninh province.

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.
Microplastics in commercial fish digestive tracts from freshwater habitats in Northern Thailand
Researchers examined the digestive tracts of commercial freshwater fish species from Northern Thailand and found microplastics present in all species studied. Fibers were the most common type of microplastic detected, followed by fragments, with varying abundances depending on the fish species and habitat. The findings raise awareness about microplastic contamination in Thai freshwater fish and the potential for human dietary exposure.

Microplastics were found in two economically important freshwater fish species sampled across Guangdong Province, China, with fibers being the most common type and polypropylene and polyester the dominant polymers. The widespread contamination of commercial freshwater fish in China indicates a significant pathway for human exposure through fish consumption.

Microplastics in natural seafood of Vietnam and their potential exposure to consumers: A mini review
Researchers reviewed studies on microplastic contamination in seafood from Vietnam, finding plastic particles in 21 marine species including fish, shrimp, and shellfish, with fish carrying the highest loads. The findings highlight that consumers eating Vietnamese seafood regularly are ingesting microplastics, raising public health concerns about exposure through a major food source.
