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.
Incidence of Watershed Land Use on the Consumption of Meso and Microplastics by Fish Communities in Uruguayan Lowland Streams
Researchers found that fish in urbanized Uruguayan lowland streams ingested significantly more meso- and microplastics than fish in streams draining extensive ranching land, with 309 individuals from 29 species analyzed. The results link watershed land use intensity to plastic contamination levels in freshwater fish communities.
Occurrence of microplastics in the gastrointestinal tract of Amazonian fish species with different feeding habits
Microplastics were found in the gastrointestinal tracts of multiple Amazonian fish species with different feeding habits from Lake Janauacá and the Anavilhanas Archipelago, with feeding strategy influencing ingestion rates—underscoring widespread microplastic contamination even in remote Amazon basin aquatic ecosystems.
Urbanization is a major influence on microplastic ingestion by sunfish in the Brazos River Basin, Central Texas, USA
Researchers documented microplastic ingestion by bluegill and longear sunfish in the Brazos River Basin, Central Texas. The study found that urbanization was a major factor influencing microplastic ingestion rates, with fish from more urbanized watersheds containing higher quantities of microplastics, highlighting the connection between land use and freshwater contamination.
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.
Ingestion of plastic debris by commercially important marine fish in southeast-south Brazil
Scientists visually examined 965 specimens of eight commercially exploited fish species off the southeast-south coast of Brazil for plastic debris ingestion, finding plastic in multiple species across different marine habitats.
First record of plastic ingestion by an important commercial native fish (Prochilodus lineatus) in the middle Tietê River basin, Southeast Brazil
