ClearPresence and Abundance of Microplastics in Benthic Organisms from Some Niger Delta, Nigeria Coastal Rivers
Researchers investigated the presence and abundance of microplastics in benthic organisms collected from coastal rivers in the Niger Delta region of Nigeria, documenting contamination levels in organisms from these ecologically significant waterways.
Baseline characterisation of microplastics in surface water, sediment, and seafood from the Escravos Estuary, Nigeria
Researchers established baseline microplastic data for the Escravos Estuary in Nigeria's Niger Delta, finding contamination in water, sediment, fish, crabs, and periwinkles. Fibers and fragments were the most common types, with nylon and PET identified in seafood samples. Since local communities depend heavily on these waterways for food, the findings highlight a direct route for microplastic ingestion through the consumption of contaminated seafood.

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.
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.

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.
Macrodebris and microplastics pollution in Nigeria: first report on abundance, distribution and composition
Researchers conducted the first assessment of macrodebris and microplastics in five rivers in southeastern Nigeria, finding plastics as the dominant macrodebris type at 59% and documenting small microplastic particles as small as 11 micrometers across all sites.
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.
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.
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.
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.
Freshwater insects of different feeding guilds ingest microplastics in two Gulf of Guinea tributaries in Nigeria
Scientists collected freshwater insects from two Nigerian tributaries of the Gulf of Guinea and found microplastics ingested across different feeding guilds, providing rare baseline data on microplastic contamination of African freshwater ecosystems.
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.
Studies on the Impact of Microplastics in Freshwater Systems: Biota Could Be Vital Indicators in Delta State, Nigeria
Researchers investigated the effects of microplastics on freshwater systems in Delta State, Nigeria using aquatic plants as bioindicators, conducting bimonthly sampling from June to August to examine microplastic occurrence and pollution intensity in water bodies.
Occurrenceand characteristics of microplastics in benthic species from mangrove wetlands of Hainan, South China
