ClearIngestion and accumulation of microplastics in small marine fish and potential human exposure: case study of Binh Dinh, Vietnam
Researchers investigated microplastic accumulation in five small marine fish species commonly consumed by coastal communities in Binh Dinh, Vietnam. They found microplastics present in fish from all sampling sites, with seasonal and species-level variation in contamination levels. The study estimates potential human dietary exposure to microplastics through fish consumption and raises food safety concerns for coastal populations relying on local seafood.

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 accumulation of microplastics in fish freshwater in the Mun river, Thailand
Researchers examined microplastic accumulation in freshwater fish from the Mun River in Thailand, finding plastic particles in the gastrointestinal tracts of multiple fish species. Fiber-shaped microplastics were the most commonly ingested type, likely originating from textile and domestic waste sources. The findings highlight the potential for human dietary exposure to microplastics through consumption of freshwater fish that are widely eaten throughout Southeast Asia.

Researchers characterized microplastic contamination in commercially consumed marine fish landed in Bali, Indonesia, examining microplastic presence, type, and polymer composition across multiple fish species. The study found widespread microplastic ingestion in food fish, raising concerns about human dietary exposure through seafood consumption in the region.
Contamination of stream fish by plastic waste in the Brazilian Amazon
Researchers evaluated plastic contamination in small fish from Amazonian headwater streams in Brazil, finding widespread plastic pollution in these understudied tropical freshwater ecosystems and characterizing the shapes, sizes, and abundance of plastic items ingested.
Assessing microplastic abundances in freshwater fishes in a subtropical African reservoir
Scientists examined freshwater fish from a reservoir in South Africa and found microplastics in nearly 87% of the fish across eight species. Fibers were the most common type of microplastic, found in both the gills and digestive tracts of the fish. Since these fish are consumed by local communities, the widespread contamination raises concerns about human exposure to microplastics through freshwater fish, an understudied area compared to marine seafood.
Microplastics in siluriform fish sold in Itacoatiara (AM), Brazil
Researchers in Brazil found that more than 83% of two commercially sold catfish species (Pterygoplichthys pardalis and Hoplosternum littorale) collected from Amazonian floodplains were contaminated with microplastics, averaging about 2.7 particles per fish. The dominant particle types were fibers and fragments, pointing to textile and packaging waste as key sources. Because these fish are widely consumed locally, this study highlights a direct route through which microplastics enter the human diet in the Amazon region.
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.
Investigation of microplastic ingestion in commercial fish from Surabaya river, Indonesia
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.
Diet composition of a native fish species in a neotropical lentic environment
This study characterized the diet and feeding habits of Hoplosternum littorale, a native South American armored catfish, in neotropical lentic environments. Understanding the trophic ecology of native fish species helps establish ecological baselines for monitoring how pollution, including microplastics, may affect food web dynamics.
Literature Review: Identification of Microplastics In Tropical Marine Fish
This literature review examined studies on microplastic identification in tropical marine fish, covering ingestion rates, particle types, and detection methods. The review found widespread microplastic occurrence in tropical fish species and highlighted the need for standardized methods to enable cross-regional comparisons in fish contamination research.

Abundance, characteristics, and risk assessment of microplastics in indigenous freshwater fishes of India
Researchers examined microplastic contamination in five widely consumed freshwater fish species from India and found plastic particles in all specimens, with fibers being the most dominant type. Evidence of microplastics in edible fish tissue indicates translocation from the gut, suggesting a pathway for human exposure through consumption. Risk assessment showed that while microplastic abundance posed a low quantitative risk, the polymer types identified indicated a high hazard potential for the fish species studied.
