Microplastics analysis in the gills and gastrointestinal tract of fishermen’s catch at Belawan River North Sumatera, Indonesia
AI summary Read the abstract
Researchers analyzed microplastics in the gills and gastrointestinal tracts of 93 fish specimens across five species collected from Belawan River, North Sumatra, finding 134 total microplastic particles dominated by fibers, fragments, and films in colors including black, green, blue, orange, brown, and red, with Plotosus canius showing the highest abundance at 12 particles per individual.
Abstract Microplastics produce from macro sized plastics which are degraded into particles size 0.1 – 5 mm. Fish ingest microplastics because their mistake for food, with microplastics sizes as the size of category plankton species which are the food supply for fish microplastics ingest to the digestive organ and the gills. The research was catching a total of 93 specimens of the fish Oreochromis mossambicus, Channa striata, Plotosus canius, Scatophagus argus and Lutjanus indicus in February 2023 at Belawan River. Microplastics isolation analysed in animals’ laboratory, faculty of mathematics and natural sciences, Universitas Sumatera Utara Indonesia. According to the results, there was three shapes of microplastics, fiber, fragments, and films. A total of 134 microplastics particles were 5 species of sample, O. mossambicus were 9.7 abundance of microplastics, C. striata were 3.6 abundance of microplastics, P. canius were 12 abundance of microplastics, S. argus were 6.0 abundance of microplastics and L. indicus were 4.3 abundance of microplastics . The colour of microplastics was found in 46 black, 32 green, 24 blue, 23 orange, 7 brown and 2 red.

AI summary Read the abstract
Researchers examined microplastic contamination in the gills and digestive tracts of fish collected from seagrass ecosystems around Bintan Island, Indonesia, using optical microscopy on ten samples per species. They found five morphological forms of microplastics at abundances ranging from 49.67 to 122.38 particles per gram dry weight, with transparent particles predominating in the digestive tract and black particles in the gills.

AI summary Read the abstract
Researchers identified and characterized microplastic pollutants in the gastrointestinal tracts of four commercially important fish species (Johnius borneensis, J. macropterus, Osteomugil engeli, and Sardinella fimbriata) collected from the east coast of North Sumatra Province, Indonesia between May and December 2022. The study quantified microplastic types, shapes, and colors across multiple sampling sites and species to assess contamination levels in these economically significant fisheries.
