ClearMicroplastics 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.

Multiple polymer types were identified in both water and biota samples.
Characterization of Microplastics in the Sediment of Azuabie and Eagle Island Creeks, Rivers State, Niger Delta
Researchers characterized microplastics in sediment samples from Azuabie and Eagle Island Creeks in Rivers State, Nigeria (Niger Delta), identifying microplastic abundance, morphology, color, and polymer types in a region where these particles can accumulate in fish tissues, transport pathogens, and concentrate toxic pollutants in the marine environment.
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.
Microplastic particles in river sediments and water of southwestern Nigeria: insights on the occurrence, seasonal distribution, composition, and source apportionment
Researchers surveyed microplastic contamination in river water and sediments across southwestern Nigeria, providing some of the first baseline data for the region. They found microplastics at every sampling site, with fibers and fragments being the most common forms, and concentrations varying by season and location. The study points to urban runoff, agricultural activities, and inadequate waste management as the primary sources of this pollution.
Prevalence and risk assessment of microplastics in the Nile Delta estuaries: “The Plastic Nile” revisited
Researchers assessed microplastic prevalence and health risks in estuaries of the Nile Delta in Egypt, finding MPs in water, sediment, and seafood samples across multiple sites. Risk assessment indicated potential exposure concern for communities relying on these estuaries for food and water.
Microplastics Pollution in Nigerian Aquatic Ecosystems: Sources, Pathways, Impacts, and Mitigation Strategies. A Review
This review synthesized evidence on microplastic contamination across Nigerian aquatic ecosystems, including rivers, lagoons, seafood, and drinking water. The authors describe complex pollution pathways and impacts on organisms across trophic levels, while highlighting the need for Nigeria-specific research and stronger waste management policies.
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.

Eco-toxic Risk Assessment of microplastics in water and sediment across Nigeria Offshore, Gulf of Guinea
Researchers assessed microplastic distribution and ecological risk in water and sediment across Nigeria's offshore waters in the Gulf of Guinea. They found microplastic concentrations of 48 particles per liter in water and 73 particles per kilogram in sediment, with the Eastern Zone showing the highest contamination levels. The ecological risk assessment revealed high polymer risk index values across all zones, indicating potential environmental concern for these marine ecosystems.
