Investigation of microplastic ingestion in commercial fish from Surabaya river, Indonesia
Summary
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.
Microplastics (MPs) were recognized as emerging environmental contaminants and ubiquitously distributed in aquatic environments, including in commercial biota. Fish are estimated as one of the most susceptible aquatic biota to ingesting microplastic (MP). Commercial fish cultivation is commonly developed in urban rivers. This situation may lead to food web safety and human health risks because most fish products are commercially available for consumption. Surabaya River, one of the main rivers in Indonesia, has been polluted by MPs. This river takes essential parts for providing clean water for Surabaya City and fishery. This study aimed to investigate: (1) MP ingestion, abundance, characteristics in commercial fish species in Surabaya River, and (2) potential influencing factors to MP ingestion in the fish. The MP ingestion was found in gills and gastrointestinal tracts (GITs) of seven commercial fish species from the Surabaya River. The highest MP abundance was found in the gill of Trichopodus trichopterus (280.73 ± 162.25 particles/g WW), in the GIT of Rasbora argyrotaenia (358.75 ± 121.98 particles/g WW), and in Notopterus notopterus (186 ± 130.81 particles/individual). The MP abundance was positively correlated to fish body size. The predominant MP polymer in both fish organs was cellophane. These MPs were mostly fiber-shaped, large-sized, and black-colored. The MP ingestion in the fish might be influenced by active/passive uptake routes, specific feeding habits, preference habitats, fish size, and MP characteristics. This investigation reveals the occurrence of MP ingestion in commercial fish, which is closely associated with human health risks via trophic transfer by accidental consumption.

The Occurrence of Microplastic in Suckermouth Armored Catfish in Krukut River, Jakarta, Indonesia
Microplastics were found in the digestive tracts of suckermouth armored catfish from the Krukut River in Jakarta, Indonesia, with prevalence varying by river segment. The findings indicate that even urban river fish used as a water supply source are contaminated with microplastics, raising food safety concerns.
First Evidence of Microplastic Ingestion by Riverine Fish From the Freshwater of Northwest Peninsular Malaysia
Researchers found microplastics in the guts of multiple fish species from two rivers in northwest Malaysia, with some species averaging nearly 50 microplastic particles per gram of body weight. The dominant particles were fibers and fragments of polyethylene and polypropylene — findings that signal widespread contamination of freshwater food sources and raise concerns about human exposure through fish consumption.
The concentration of microplastic in water and fish (Gambusia affinis) collected from Brantas River
Researchers measured microplastic concentrations in water and in the bodies of mosquitofish (Gambusia affinis) from the Brantas River in Malang, Indonesia, finding contamination in both. The study confirms that freshwater fish in Indonesian urban rivers are ingesting microplastics, raising concerns about human exposure through fish consumption.
