This study found microplastics in the tissues of Nile tilapia cultured in freshwater, with particles identified in gills, intestines, and muscle tissue. The results highlight the potential for microplastic transfer from farmed fish to human consumers.
The Presence of Microplastics in the Genus Oreochromis: A Review
This review summarizes evidence of microplastic contamination in Oreochromis tilapia species across multiple geographic regions, examining abundance, polymer types, and potential pathways of MP ingestion, with implications for seafood safety and aquaculture management.
Identificação de polímeros de microplásticos encontrados no trato digestivo de peixes do Lago de Amatitlán, Guatemala
Using FTIR-ATR spectroscopy, 68 microplastics from the gastrointestinal tracts of 36 fish from Lake Amatitlán, Guatemala were identified and characterized, representing 10% of the total extracted particles. The Portuguese-language study determined the predominant polymer types and likely contamination origins in fish from this Central American lake ecosystem.
Evaluation of Toxicological Risks and Effects of Microplastics on Nile Tilapia (Oreochromisniloticus) under in Vitro Laboratory Conditions
This laboratory study evaluated the toxicological effects of microplastics on Nile tilapia (Oreochromis niloticus) under controlled conditions, finding measurable harm at the concentrations tested. The results have implications for managing fish health in aquaculture operations with microplastic-contaminated water.
Microplastics pollution in tropical lakes: water, zooplankton, and fish in Central Mexico
Researchers analyzed microplastic presence in water, zooplankton, and fish across two tropical lakes in central Mexico. The study found microplastics in all compartments including rotifers, microcrustaceans, and fish of the genus Chirostoma, providing evidence of microplastic transfer through freshwater food chains in tropical ecosystems.
Identifikasi Cemaran Mikroplastik pada Ikan Nila (Oreochromis niloticus) dan Ikan Puyau (Osteochilus vittatus) di Perairan Waduk Benanga, Samarinda
Researchers examined tilapia and puyau fish from the Benanga Reservoir in Samarinda, Indonesia, and found microplastic contamination in all 12 fish samples. A total of 155 microplastic particles were detected across the gills and digestive tracts, with fiber-type particles dominating in both species. The study highlights that plastic waste mismanagement around the reservoir is leading to microplastic accumulation in locally consumed fish.
