ClearAbundance, 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.
Integrated analysis of microplastics origins and impact on prominent aquaculture ecosystems in Bangladesh
Researchers surveyed microplastic contamination in aquaculture ponds in Bangladesh, finding widespread particles in both the water and farmed fish including tilapia and pangas.
