ClearMicroplastic 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 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 the Effect of Anthropogenic Activities on Aquatic Life in Ugbo-Aiyetoro Water-way, Southwestern Nigeria
This study investigated the effects of eutrophication from human activities on phytoplankton and zooplankton biodiversity in a coastal Nigerian community, finding reduced biodiversity in heavily impacted areas. While focused on nutrient pollution rather than microplastics, it documents the ecological consequences of inadequate waste management in coastal communities.

Researchers examined microplastic contamination in sediments from four sites along Lagos Lagoon, Nigeria, finding MP abundance of 9–12 particles/kg with PET fibers dominating, and identifying potentially toxic polymers that pose long-term ecological risks to this West African coastal ecosystem.
Heavy Metals and their Effects on Macroinvertebrates Present in the Ojo River, Lagos, Nigeria
Researchers investigated heavy metal concentrations in the tissues of crab, prawn, and crayfish from the Ojo River in Lagos, Nigeria, assessing contamination levels in commercially harvested crustaceans and their implications for human health and aquatic ecosystem integrity.
Seasonal variations of water physico-chemistry, heavy metal concentrations and ecological abundance and biodiversity of fish from two Lagoon streams
Researchers monitored water chemistry, heavy metal concentrations, and fish biodiversity across seasons in two Nigerian lagoon streams. Heavy metals often adsorb to microplastics in aquatic environments, and documenting baseline contamination levels is important for understanding cumulative pollution impacts on freshwater fish communities.
Pertubation of Road Construction and Inorganic Sedimentation on the Macroinvetebrate Fauna in the Midstream Segment of Qua Iboe River, Nigeria
Researchers investigated the effects of road construction and inorganic sedimentation on macroinvertebrate communities in the Qua Iboe River in Nigeria, finding that elevated physico-chemical pollution parameters in perturbed river segments significantly disrupted benthic fauna. The study demonstrated that construction-driven sedimentation poses a measurable ecological threat to freshwater invertebrate biodiversity.
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.
Anthropogenic drivers of pollutant presence and composition in first-order streams of the Ona River System, Ibadan, Nigeria
Researchers assessed physicochemical parameters, heavy metals, and microplastic contamination across eight urban rivers in southwestern Nigeria, examining how rapid urbanization drives pollutant loading and shapes contaminant composition in first-order streams of the Ona River system.
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.
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.
Characterization of Microplastics Residue in Water and Biota of Majidun Estuarines, Lagos Nigeria
Researchers characterized microplastics in surface water and commercially harvested aquatic species from the Majidun River estuary in Lagos, Nigeria, providing the first documented assessment of microplastic pollution in this location. Multiple polymer types were identified in both water and biota samples.
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.
Presence and Abundance of Microplastics in Benthic Organisms from Some Niger Delta, Nigeria Coastal Rivers
Researchers examined benthic organisms—crabs, oysters, shrimps, lobsters, and others—from seven rivers in Nigeria's Niger Delta, finding 100% microplastic presence across all species and all sampling sites.
Water pollution and its impact on human health in Nigeria Authors
This study examined the causes and health effects of water pollution in Nigeria, where millions of people are affected by contaminated water sources from industrial waste, oil spills, and agricultural runoff. Researchers found that heavy metals, pathogens, and microplastics significantly degrade water quality, leading to waterborne diseases and long-term health problems. The study emphasizes the urgent need for improved sanitation infrastructure, stronger environmental regulations, and community-based clean water initiatives.
