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.
