Fish accumulated microplastics in their digestive tracts and body tissues, raising concerns about human exposure through seafood consumption in the region.
Microplastic load and distribution in the respiratory and digestive systems of some commercial fish species in the southwestern coast of Bangladesh
Researchers assessed the distribution of microplastics in both the digestive and respiratory systems of three commercial fish species from Bangladesh's southwestern coast, finding contamination in all sampled fish. Digestive tract accumulation was higher than in gill tissue, and polypropylene and polyethylene fibers were the most common plastic types identified.
Unveiling Microplastics in Commercial Brackish Water Fishes from the Lower Meghna River Estuary of Bangladesh
Researchers found microplastics in the digestive tracts of three commonly eaten fish species from the Meghna River estuary in Bangladesh, with one species averaging nearly 23 particles per fish. Fibers were the dominant shape, and several of the plastic types identified scored high on a polymer hazard index. Since these fish are a dietary staple for local populations, the study highlights a direct route of microplastic exposure for millions of people in Bangladesh.
Bioaccumulation of microplastics in the edible tissues of fish collected from urban lakes of Bangladesh: a potential exposure to public health
Researchers analyzed fish from urban lakes in Bangladesh and found microplastics present in the edible tissues of all species examined, with fibers being the most common type. The level of contamination varied by fish species and lake location, reflecting differences in local pollution levels. The findings raise public health concerns about microplastic exposure through freshwater fish consumption in densely populated urban areas.
Quantification, characterization and risk assessment of microplastics and mesoplastics in aquafarms of a leading fish-producing nation
Researchers assessed plastic contamination — including both microplastics and the often-overlooked mesoplastic size range — in water, sediments, and fish from aquaculture farms in northern Bangladesh. Concentrations in fish gut tissue were four to five times higher than in muscle, and over 80% of particles were fibers, with polyamide and polyethylene most common. The study argues that current regulations systematically underestimate plastic contamination in farmed fish by ignoring mesoplastics, posing an unrecognized food safety concern.
The pervasiveness of microplastic contamination in the gastrointestinal tract of fish from the western coast of Bangladesh
Researchers found microplastics in every individual fish examined from the western coast of Bangladesh, with an average of 7.1 particles per specimen, and demersal species accumulating more microplastics than pelagic species near the world's largest mangrove ecosystem.
Microplastics in fish culture ponds: abundance, characterization, and contamination risk assessment
Researchers surveyed five types of fish farming ponds in Bangladesh and found microplastics in all sediment and water samples, with higher contamination near industrial areas. The most common microplastics were small fragments and fibers made of polyethylene and polypropylene, likely originating from packaging waste and fishing gear. The findings raise concerns about microplastic contamination in farmed fish that are destined for human consumption.
Microplastic Contamination of Wild and Captive Flathead Grey Mullet (Mugil cephalus)
Researchers compared microplastic ingestion in wild and captive flathead grey mullet (Mugil cephalus) in Hong Kong, finding contamination in 60% of wild fish versus only 16.7% of farmed fish, with wild individuals averaging 4.3 plastic items each. Polypropylene fibres under 2 mm were the dominant type, and microplastic abundance correlated positively with body size in wild fish.
Microplastic abundance in commercially important brackish water fin-fish from the Bay of Bengal
Researchers analyzed the gastrointestinal tracts of seven commercially important fish species from the Bay of Bengal, confirming widespread microplastic contamination dominated by fibers and fragments, with implications for seafood safety.
Microplastics in pelagic and demersal fishes from the Meghna River estuary, Bangladesh
Scientists examined 80 fish from the Meghna River estuary in Bangladesh and found microplastics in over 81% of them, with an average of about 7 particles per fish. Polyethylene, polypropylene, and nylon fibers were the most common types found in the fish digestive tracts. Since these are species commonly eaten by local communities, the findings raise concerns about microplastic exposure through the food chain.
Prevalence of microplastics in commonly consumed fish species of the river Old Brahmaputra, Bangladesh
Researchers found microplastics in nearly 59% of edible fish from Bangladesh's Old Brahmaputra river, with polyethylene fibers and pellets dominating, and ingestion rates linked to fish size, feeding behavior, and downstream location.
Microplastic load and distribution in the respiratory and digestive systems of some commercial fish species in the southwestern coast of Bangladesh
This Bangladeshi study investigated microplastic occurrence in the respiratory and digestive systems of three commercially important fish species from the southwestern coast.

Researchers measured microplastic contamination in two commonly eaten fish species from the Bay of Bengal, examining both gills and digestive tracts. Microplastics were found in all fish studied, with differences in accumulation based on the species' feeding habits and where they live in the water column. Since these fish are widely consumed by local populations, the findings raise concerns about human microplastic intake through seafood.
Occurrence of microplastics in fish gastrointestinal tracts belongs to different feeding habits from the Bangladesh coast of the Bay of Bengal
Researchers examined the gastrointestinal tracts of six commercial fish species from the Bangladesh coast of the Bay of Bengal and found microplastics in all species studied. A total of 696 microplastic particles were identified, ranging from 0.3 to 5 millimeters in size, with varying contamination levels across different feeding habits. The study highlights that microplastic pollution is widespread in commercially important fish from this region.
Microplastics occurrence in water, sediment and edible small indigenous fish species in seasonal freshwater wetland ecosystems of Bangladesh
Researchers found microplastics in the guts, gills, and muscle tissue of three commonly eaten fish species from seasonal wetlands in Bangladesh. Dried fish contained more microplastics than fresh fish, suggesting that the drying process concentrates plastic particles. Since these small fish are a dietary staple for local communities and are often eaten whole, this represents a direct pathway for microplastic exposure in human diets.
