Microplastic Pollution in Indigenous Fish From the Padma River, Bangladesh: A Case Study
Researchers examined indigenous fish species from the Padma River in Bangladesh and found microplastics in the gastrointestinal tracts of all species studied, with fibers being the dominant type. The abundance and types of microplastics varied across species, reflecting differences in feeding habits and habitat. The findings highlight the widespread presence of microplastic contamination in an important inland waterway and its potential impact on food security in the region.
Characteristics of Microplastics in Water and Fish and Their Relationship with Migration from the East Coast of Surabaya, Indonesia
Researchers characterized microplastic contamination in water and fish from the East Coast of Surabaya, Indonesia, finding approximately 0.46 particles/L in water with fragments (79.9%) and black-colored particles (20-40 µm) dominant, and detecting MPs in gills and digestive tracts of eight fish species.
Ingestion of Microplastics by Commercial Fish in Skudai River, Malaysia
Microplastics were found in the gastrointestinal tracts of commercial fish in a Malaysian river, adding to growing evidence of widespread contamination in freshwater fish. The findings raise concerns about the potential transfer of microplastics to humans who consume these fish.
Characterization of microplastics in commercially valued Gangetic fishes and its exposure assessment on humans
Researchers characterized microplastics in commercially sold fish from the Ganges River in India, finding plastic contamination across multiple species and providing an initial exposure assessment for human consumers who rely on freshwater fish as a primary protein source.
Ecological and health risks of microplastic contamination in edible fish from the Musi River Palembang, Indonesia
Researchers found microplastics in all ten fish species sampled from Indonesia's Musi River, with fragment-shaped PET, PE, and PVC particles being most common, though current consumption levels still put fish-eating locals in a low health-risk category. The findings underscore the need for ongoing monitoring and better plastic waste management to prevent risk from increasing over time.
Abundance, distribution and composition of microplastics in sediment and fish species from an Urban River of Bangladesh
Researchers examined microplastic contamination in both river sediment and fish from the Turag River in Bangladesh, which separates an industrial city from the capital Dhaka. They found microplastics in all sediment and fish gut samples, with fragment-type particles dominating in sediment and fibers most common in fish. The study highlights that urban rivers in densely populated areas can serve as significant conduits of microplastic exposure for both aquatic life and the people who consume river fish.
THE ABUNDANCE OF MICROPLASTICS IN THE DIGESTIVE SYSTEM OF SILVER BARB (Barbonymus gonionotus) FROM THE WATERS OF THE KARANG MUMUS RIVER, SAMARINDA CITY, INDONESIA
Microplastics were found in all 20 silver barb fish examined from the Karang Mumus River in Samarinda, Indonesia, with an average of 22 particles per fish — mostly fiber-shaped and predominantly polyethylene. This is the first report of microplastic ingestion by fish in this river system, indicating that microplastic contamination has reached even rivers in less-studied parts of Southeast Asia. The results raise food safety concerns since silver barb is eaten by local communities, and suggest broader environmental contamination of the river ecosystem.
