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.

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.

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.

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.

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.

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.

Microplastic pollution in the gastrointestinal tract of giant river catfish Sperata seenghala (Sykes, 1839) from the Meghna River, Bangladesh

Researchers examined the digestive tracts of giant river catfish from the Meghna River in Bangladesh and found microplastics in 90 percent of the fish sampled. The most common particles were polypropylene-polyethylene fragments smaller than 100 micrometers, with the highest contamination near densely populated areas. The findings add to growing evidence that freshwater fish in South Asian rivers are widely contaminated with microplastics.

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.

Microplastic Occurrences in Freshwater Fish of Bangladesh

This review synthesizes research on microplastic contamination found in freshwater fish across Bangladesh, where rapid population growth and urbanization have led to significant plastic pollution. Researchers found that fibers are the most commonly detected microplastic type in fish tissues, raising concerns about impacts on gut health and immune function. The study highlights the need for more comprehensive monitoring given Bangladesh's heavy reliance on freshwater fish as a dietary staple.

Researchers characterized microplastic contamination in fish and sediment from the Brahmaputra River in Bangladesh, the country's longest river. They found microplastics in all fish and sediment samples, with fibers being the most common type, and bottom-dwelling fish species containing more particles than those living near the surface. The study provides important baseline data on freshwater microplastic pollution in a major South Asian river system.
