Ingestion of Microplastics by Commercial Fish in Skudai River, Malaysia
AI summary Read the abstract
Microplastics were found in the gastrointestinal tracts of commercial fish in a Malaysian river, adding to growing evidence of widespread contamination in freshwater fish. The findings raise concerns about the potential transfer of microplastics to humans who consume these fish.
Microplastics are plastic particles less than 5 mm and have been classified as contaminants of emerging concern. In recent years, the ubiquity of microplastics has caused a serious threat to aquatic animals worldwide. Over the past decade, the ingestion of microplastics has been extensively reported in various marine animals. However, studies on ingested microplastics in the aquatic animal in freshwater ecosystems are still scarce. Therefore, the presence of microplastics in the gastrointestinal (GI) tract of freshwater fish in Skudai River was investigated. Sixty fish were caught belonging to 6 species and 3 feeding habits. The analysis shows all species ingested microplastics. By individual, only 40% of the fish ingested microplastics. Microplastics with size between 1 to 5 mm were the most dominant particles found in the GI tract. There was a significant difference in number of microplastics among different species. A positive correlation was observed between the number of microplastics and Fulton’s condition, body weight and weight of the GI tract. This investigation represents the first study on the interaction between microplastics and aquatic animals in fishing and urban area of this country, where fish are consumed by local people.

First Evidence of Microplastic Ingestion by Riverine Fish From the Freshwater of Northwest Peninsular Malaysia
AI summary Read the abstract
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.
Occurrence, distribution and characteristics of microplastics in gastrointestinal tract and gills of commercial marine fish from Malaysia
AI summary Read the abstract
Researchers examined 158 commercial marine fish from 16 species in Malaysia and found microplastics in the gastrointestinal tracts and gills of all species studied. Fibers were the most common microplastic type, and the contamination levels varied between sampling locations. The findings add to growing evidence that microplastics are widespread in commercially important fish species, raising questions about the potential for human exposure through seafood consumption.
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.
