Multiple polymer types were identified in both water and biota samples.
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.
Occurrence and distribution of microplastics in water, sediment, and aquatic insects of the Owena River, Osun state, Nigeria
Researchers surveyed microplastic contamination in water, sediment, and aquatic insects from the Owena River in Nigeria over a 12-month period. Microplastics were found across all sample types and river sections, with fibers and fragments being the most common forms. The study suggests that aquatic insects can serve as biological indicators of microplastic pollution in freshwater ecosystems.
