RETRACTED: Characterization of microplastic pollution in the Pasur river of the Sundarbans ecosystem (Bangladesh) with emphasis on water, sediments, and fish

AI summary · Read the abstract

This retracted study characterized microplastic pollution in the Pasur River of Bangladesh's Sundarbans, finding plastic particles in 100% of water, sediment, and fish samples analyzed. Microplastics were found in both the digestive tracts and muscle tissue of nine fish species, with some species accumulating high levels in the edible flesh. Note: this paper has been retracted, so its findings should be treated with caution.

Microplastics pollution in water and sediment matrices of the old Brahmaputra River, bangladesh: an ecological risk appraisal of an urban river

AI summary · Read the abstract

Seasonal sampling of surface water and sediment in the Old Brahmaputra River, Bangladesh found microplastic concentrations highest in winter (over 4 million items/km² in water), dominated by polypropylene fibers and fragments, with a Pollution Load Index indicating low but measurable ecological risk. The study provides baseline contamination data for an ecologically important South Asian urban river, establishing a foundation for monitoring and policy responses in a region with rapidly growing plastic use.

Microplastics in River Sediments Around the Dhaka City: A Case Study for Occurrence and Quantification

AI summary · Read the abstract

Researchers measured microplastic concentrations in river sediments around Dhaka, Bangladesh, finding widespread plastic particle pollution in one of the world's most densely populated cities — adding to evidence that heavily urbanized river systems are major reservoirs of microplastic contamination.
