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 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.

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.

Occurrence of Microplastics in the Gastrointestinal Tracts of Edible Fishes from South Indian Rivers

Researchers isolated and characterized microplastics from the gastrointestinal tracts of five edible fish species collected from the Kollidam and Vellar rivers in Tamil Nadu, Southern India. They found 315 microplastic particles across 23 fish, dominated by fibers (85.7%) in Kollidam river fish and fragments (14.3%) in Vellar river fish, with particle sizes ranging from 109 to 284 µm, indicating widespread dietary exposure to microplastics in commercially harvested freshwater fish.
