Microplastic composition in water, sediment, and fish in the Middle Section of the Kahayan River: Implications for the sustainability of floating net cage aquaculture
AI summary Read the abstract
Researchers sampled water, sediment, and fish across five stations along Indonesia's Kahayan River, detecting microplastics in all compartments at mean abundances of 3.14 particles/L in water and 3.63 particles per fish — with concentrations highest near intensive aquaculture zones, suggesting active transfer from abiotic to biotic components and risks to food safety.
Microplastics are emerging pollutants widely detected in freshwater ecosystems, including rivers that act as major pathways for plastic waste transport to the ocean. This study aimed to analyze the abundance and characteristics of microplastics in water, sediment, and fish from the middle section of the Kahayan River and to assess their implications for the sustainability of floating net cage aquaculture. Sampling was conducted at five stations representing different levels of anthropogenic activity. Water, sediment, and fish samples were processed using the wet peroxide oxidation (WPO) and NaCl density separation methods, followed by microscopic identification. The results revealed that microplastics were widely distributed across all environmental compartments, with mean abundances of 3,14 particles/L in water, 7,31 particles/kg-dw in sediment, and 3,63 particles/individual in fish. The highest concentrations were found in stations with intensive aquaculture, dense settlements, and active trading areas. The dominant types were fibers and fragments, mainly white, blue, and black/gray in color. Particles <300 µm predominated in water and fish, whereas those >1000 µm were more abundant in sediment. These findings indicate the transfer of microplastics from abiotic to biotic components, suggesting potential bioaccumulation within the aquatic food chain. The presence of microplastics in aquaculture environments may degrade water and fish quality, posing threats to aquaculture sustainability and food safety for local communities along the Kahayan River.

AI summary Read the abstract
Researchers sampled water, sediment, and fish across four stations in the downstream Kahayan River and found microplastics present at every site — averaging 3.22 particles/L in water and 2.12 particles per fish — with fiber shapes and HDPE/LDPE polymers dominating, pointing to domestic and fishery waste as the primary sources.
Investigation of microplastic ingestion in commercial fish from Surabaya river, Indonesia
AI summary Read the abstract
Researchers examined microplastic contamination in commercial fish species from the Surabaya River in Indonesia, a major urban waterway used for both clean water supply and fisheries. They found microplastics present in all fish studied, with variations in abundance linked to feeding behavior and habitat. The findings raise concerns about food safety for communities that rely on river fish as a dietary staple.
Microplastic contamination in water, sediment, and fish from the Kahayan River, Indonesia

Researchers assessed microplastic contamination in water, sediment, and fish from the Kahayan River in Central Kalimantan, Indonesia. They found microplastics present across all sample types, with fibers and fragments being the most common forms, and identified polyethylene and polypropylene as the dominant polymer types. The study provides the first baseline data on microplastic pollution in this region and highlights the widespread nature of contamination in Indonesian freshwater systems.
Influence of fish length and weight on microplastic accumulation in freshwater fish from the Kahayan river, Indonesia
AI summary Read the abstract
Scientists found tiny plastic bits (mostly plastic fibers) inside most fish—65%—caught in an Indonesian river, with bigger fish tending to carry larger plastic fragments. This matters because these fish are eaten by local communities, meaning microplastics could be making their way into people's diets, though more research is needed to know exactly how much and how risky this is for our health.
