Concentration, characterization, and risk assessment of microplastics in two main rivers in Birnin Kebbi, Nigeria
Researchers assessed microplastic contamination in two major rivers in Birnin Kebbi, Nigeria, that serve as sources for drinking water, fishing, and farming.

Seasonal dynamics of micro- and nanoplastics and associated pollutants in Aarin River: Insights into abundance and digestion impact
Researchers measured micro- and nanoplastics in Nigeria's Aarin River across two seasons, finding higher particle counts during the rainy season (up to 130 particles per liter in water) alongside elevated levels of polycyclic aromatic hydrocarbons and heavy metals. The data highlight how seasonal rainfall flushes plastics and co-contaminants into West African freshwater systems that communities rely on, yet which remain severely understudied.
A Comprehensive Review on Microplastics Pollution in Nigerian Aquatic Environments
This comprehensive review examined microplastic pollution across Nigerian aquatic environments, including rivers, lagoons, estuaries, and sediments. Researchers found that microplastics are widespread in Nigerian waters due to poor waste management, wastewater discharges, and industrial activities, with contamination also detected in food and drinking water consumed by the population.

Researchers characterized macro litter and microplastic abundance across five sites on the Ogunpa River in Ibadan, Nigeria during the wet season, finding high plastic contamination driven by inadequate waste management and recommending targeted environmental policy responses.
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.

Researchers assessed microplastic pollution in the surface water and sediments of Otammiri River, characterizing the abundance, morphology, polymer types, and spatial distribution of microplastics to evaluate contamination levels and ecological risks in this Nigerian freshwater system.
Assessment of Determinant Sources of Plastics and Microplastics Pollution in Inland Waterways Navigation in Lower River Niger
Researchers assessed plastic and microplastic pollution in Nigerian inland waterways, providing a baseline evaluation of contamination sources from navigation activities and identifying hotspots along the lower Niger River.
Investigation of microplastics and potentially toxic elements (PTEs) in sediments of two rivers in Southwestern Nigeria
Researchers investigated microplastic and toxic element contamination in sediments of two rivers in southwestern Nigeria. They found microplastic abundances ranging from 67 to 433 particles per kilogram, with polyethylene being the most common polymer type, along with elevated levels of chromium and lead. The study highlights how indiscriminate waste dumping is contaminating Nigerian river ecosystems and calls for stricter enforcement of environmental regulations.
Microplastic Presence in Sediment and Water of a Lagoon Bordering the Urban Agglomeration of Lagos, Southwest Nigeria
This study investigated microplastic contamination in water and sediment from a lagoon bordering Lagos, Nigeria, finding plastics present at all sites. The study is the first of its kind in the area and raises concerns about how microplastic exposure affects aquatic organisms and the communities that depend on this water body for food and livelihoods.
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 the environment in Nigeria: A rapid systematic review of the sources, distribution, research gaps and policy needs
Researchers conducted a systematic review of plastic pollution research in Nigeria and found critical data gaps — covering only 15 of 36 states — with microplastics detected in fish, insects, and water, highlighting the need for stronger policies, better monitoring, and expanded research to address the growing plastic crisis in West Africa.
Abundance, characterization, and health risk evaluation of microplastics in borehole water in Birnin Kebbi, Nigeria
Researchers analyzed borehole water samples from multiple locations in Birnin Kebbi, Nigeria, and found microplastics present in all samples tested.
