ClearMicroplastic pollution in edible marine fish from the northwestern Bay of Bengal, Bangladesh: A comprehensive assessment of occurrence, characteristics and associated ecological risks
Scientists found tiny plastic pieces in the stomachs of all fish species they tested from waters near Bangladesh, with each fish containing about 7 plastic particles on average. Since people eat these fish, this means microplastics are likely getting into our food chain, though more research is needed to understand what health risks this might pose. The study shows that plastic pollution has spread throughout marine ecosystems and is now a common part of seafood we consume.

The study highlights that microplastic pollution is widespread in commercially important fish from this region.
Abundance, characteristics and variation of microplastics in different freshwater fish species from Bangladesh
Researchers examined 48 freshwater fish from 18 species in Bangladesh and found microplastics in the digestive tracts of over 73% of the fish studied. Fibers were the most common shape, and the plastics were primarily polyethylene and polypropylene-based polymers. Bottom-dwelling fish contained more microplastics than those living higher in the water column, suggesting that contaminated sediments are a significant source of exposure for freshwater species.
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.
Tracing microplastics in marine fish: Ecological threats and human exposure in the Bay of Bengal
Researchers analyzed microplastics in nine fish species from the Bay of Bengal, finding an average of about 33 microplastic items per fish, mostly fibers. Bottom-dwelling and meat-eating fish had higher contamination levels, and the pollution was linked to untreated industrial and municipal waste. The study raises concerns about human health exposure through seafood consumption in a region where millions of people depend on fishing for food and livelihood.
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.
Baseline survey of micro and mesoplastics in the gastro-intestinal tract of commercial fish from Southeast coast of the Bay of Bengal
Researchers conducted a baseline survey of microplastics and mesoplastics in the gastrointestinal tracts of commercially important fish from the southeast coast of the Bay of Bengal, India, documenting contamination rates and particle characteristics to establish reference data for this undersampled region.
Microplastics in fishes from the Meghna River estuary, Bangladesh
Researchers found microplastics in over 80% of fish sampled from the Meghna River estuary in Bangladesh, with fibres being the most common type and polyethylene and polypropylene the dominant polymers. The contamination of these commercially important fish species signals a risk of microplastic exposure for people who eat them, particularly in communities where fish is a dietary staple.
Microplastics in fishes from the Northern Bay of Bengal
Researchers examined microplastic contamination in three fish species collected from the Northern Bay of Bengal in Bangladesh. They found an average of 3 to 9 microplastic items per fish, with fibers and irregular fragments being the most common types. The study highlights the prevalence of microplastic pollution in this important fishery region and the potential for human dietary exposure through consumption of these commonly eaten fish species.
Microplastics in freshwater wild and farmed fish species of Bangladesh
Researchers evaluated microplastic contamination in freshwater wild and farmed fish species across multiple rivers and farms in Bangladesh, comparing contamination levels between wild-caught and aquaculture-raised fish of the same species.
Microplastics (MPs) accumulation in two edible marine fish species sourced from the Bay of Bengal: Contamination level and risk assessment
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.
Prevalence of microplastic contamination in the digestive tract of fishes from mangrove ecosystem in Cispata, Colombian Caribbean
Scientists examined the digestive tracts of fish from mangrove ecosystems in Cispata, Colombian Caribbean, finding microplastics in multiple species and suggesting that mangrove habitats concentrate microplastic pollution in ways that expose fish inhabiting these nursery areas.
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.
Pervasiveness of microplastics in the gastrointestinal tract of some selected fish species from Turag River alongside the capital city of Bangladesh
Researchers found microplastics in all three species of fish collected from the Turag River near Dhaka, Bangladesh, with fiber being the dominant type at 89-93% of all particles found. The most common plastics identified were polypropylene, polystyrene, and low-density polyethylene, with the majority of particles smaller than 0.5 mm. Since these freshwater fish are a major protein source for local communities, the contamination raises concerns about microplastic exposure through the food supply in urban areas of developing countries.
