ClearXenobiotic Microplastic Pollutants in the Silver Catfish (chrysichthys Nigrodigitatus, Lacépéde, 1803) Harvested from the Ikpoba River, Benin City, Nigeria
Researchers examined microplastic contamination in the silver catfish (Chrysichthys nigrodigitatus) harvested from the Ikpoba River in Nigeria, quantifying MP levels and characteristics in this commercially important species to assess food web contamination and potential human dietary exposure.
Detection of Microplastic Pollutants and the Wellbeing of Clarias gariepinus (African Catfish) in Jama’are River, Bauchi State, Nigeria
Researchers detected multiple types of microplastics — including polyethylene, polypropylene, and PVC — in water and fish from a Nigerian river, and found that African catfish living there showed signs of tissue damage and altered blood markers, indicating that microplastic contamination is harming freshwater fish health in the region.
Microplastics profile in fishes from selected burrow pits: a case of plastic pollution in Kano metropolis, Nigeria
Researchers detected microplastics in the gastrointestinal tracts, gills, and muscle tissues of Nile tilapia and redbelly tilapia collected from burrow pits in Kano, Nigeria, confirming that plastic pollution has penetrated freshwater fish in a landlocked urban African setting.
Abundance and Seasonal Variation Of Microplastics Detected in Edible Fish Sold in Lagos State, Nigeria
This Nigerian study examined microplastic contamination in three commercially sold fish species (catfish, red snapper, and tilapia) across different seasons in Lagos State, finding microplastics in every single fish sampled. Fiber-shaped particles were most common, with higher abundances detected during the rainy season, and polyethylene was the dominant polymer type identified. The findings raise food safety concerns for consumers of seafood in West Africa, where monitoring data on microplastic contamination in fish are scarce.
Assessment of Microplastics Found in Two Fish Species of Clarias gariepinus and Oreochromis niloticus From River Niger, Lokoja, Kogi State, Nigeria
Researchers assessed microplastic contamination in two commercially important fish species, Clarias gariepinus and Oreochromis niloticus, collected from the River Niger at Lokoja in Kogi State, Nigeria. The study found microplastics present in both species, highlighting the riverine pollution burden and potential for human dietary exposure through fish consumption.
Investigation of Microplastics Contamination in African Catfish Clarias gariepinus and Nile Tilapia Oreochromis niloticus Fish Species in Owe River Ile-Oluji, Ondo State, Nigeria
Researchers examined microplastic contamination in surface water and in the tissues of two commercially important fish species (Clarias gariepinus and Oreochromis niloticus) from Nigeria's Owe River, finding microplastics in all samples and both fish species.
Microplastics Pollution of Water, Sediment, and Selected Fish Species from Bayelsa State, Nigeria
Researchers sampled water, sediment, and multiple fish species from three communities in Sagbama, Bayelsa State, Nigeria, to characterize microplastic contamination across aquatic compartments. Microplastics were detected in all matrices, with fibers dominating, establishing baseline contamination data for this Niger Delta region where residents rely heavily on local fish for food.
Microplastics Pollution of Water, Sediment, and Selected Fish Species from Bayelsa State, Nigeria
Researchers sampled water, sediment, and multiple fish species from three communities in Sagbama, Bayelsa State, Nigeria, to characterize microplastic contamination across aquatic compartments. Microplastics were detected in all matrices, with fibers dominating, establishing baseline contamination data for this Niger Delta region where residents rely heavily on local fish for food.
Plastic pollution in fish (O. niloticus and C. gariepinus) in a Nile Canal, Delta of Egypt.
Researchers examined microplastic contamination in the gastrointestinal tracts of 127 Nile tilapia and 32 African catfish from a Nilotic canal in Egypt's Delta, finding microplastic occurrence rates of 33.9% and 59.4% respectively with fibers as the dominant morphology. The study analyzed the relationship between microplastic ingestion and fish biological parameters, feeding habits, and seasonal variation.
Characterisation of Ingested Microplastic Particles and Textile Microfibres in the Gastrointestinal Tract of Demersal Fish from a Peri-Urban Open Access Lagoon in Lagos Nigeria
Researchers characterized microplastic particles and textile microfibres in the gastrointestinal tracts of demersal fish from multiple genera caught in a peri-urban lagoon bordering Lagos, Nigeria. They found evidence of microplastic ingestion across multiple fish species, contributing to the limited but growing body of data on microplastic exposure in West African aquatic food webs.
Microplastics in carnivorous fish species, water and sediments of a coastal urban lagoon in Nigeria
Researchers investigated microplastic presence in water, sediment, and carnivorous fish species from the Lagos Lagoon in Nigeria for the first time. The study found microplastics across all environmental compartments and in three fish species, suggesting that microplastic contamination is widespread in this coastal urban lagoon ecosystem and may enter local food chains.
Assessment of fishes, sediment and water from some inland rivers across the six geopolitical zones in Nigeria for microplastics
Researchers analyzed fish, sediment, and water samples from inland rivers in Nigeria for microplastic contamination, finding particles across all matrices sampled. The study provides baseline pollution data for a region with limited prior microplastic monitoring.
Occurrence of Microplastics in the Tissues of Nile Tilapia (Orechromis niloticus) from Zobe Dam, Katsina State, Nigeria
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.
Assessment of the incidence of microplastics at Ndibe, Cross River, Nigeria
Researchers assessed microplastic occurrence in water and fish samples from Ndibe Beach on the Cross River in Nigeria, documenting widespread contamination at a popular recreational site and highlighting the threat microplastics pose to aquatic ecosystems and local communities in the Niger Delta region.
Occurrence and characterization of microplastic content in the digestive system of riverine fishes

Accumulation, tissue distribution, health hazard of microplastics in a commercially important cat fish, Silonia silondia from a tropical large-scale estuary
Researchers found microplastics in the digestive tract, gills, and edible muscle tissue of a commercially important catfish species from a major tropical estuary. The most common types were PET, polyethylene, and polypropylene fibers likely originating from fishing nets and sewage. Since these microplastics were found in the muscle tissue that people eat, the study raises direct concerns about human microplastic exposure through seafood consumption.
