Occurrence and Characteristics of Microplastics in the Surface Water and Sediment of Lagos Lagoon, Nigeria
AI summary Read the abstract
Researchers characterized the occurrence, abundance, and physical properties of microplastics in the surface water and sediments of Lagos Lagoon, Nigeria, identifying key polymer types and potential local sources. This study fills an important data gap for West African urban water bodies, demonstrating that rapidly developing coastal megacities face acute microplastic contamination threatening both local fisheries and public health.
The increase in microplastic pollution has raised concerns about environmental safety in recent years. These tiny, ubiquitous, and potentially toxic plastic particles can be discharged into the environment via weathering of plastic debris and microbeads. While...

Abundance and Ecological Risk Assessment of Microplastics in Touristic Beaches along the Atlantic Coast of Lagos, Nigeria
AI summary Read the abstract
Researchers measured microplastic abundance and ecological risk across five Atlantic-coast beaches in Lagos, Nigeria, finding concentrations of 1,278 to 5,688 particles per kilogram in sand, dominated by single-use polymer types, with risk assessments indicating pollution and toxicity at all sampling points.
Sources and Environmental Distribution of Microplastics in Nigeria
AI summary Read the abstract
Researchers reviewed the sources and distribution of microplastics throughout Nigeria's environment, finding that poor plastic waste infrastructure and rapid urbanization are major contributors. The study highlights how microplastics are accumulating in soils, waterways, and food sources in regions with limited regulatory capacity to address the problem.
Abundance, distribution and characterization of microplastics in Tropical River Estuary, South East Coast of India
AI summary Read the abstract
Researchers sampled water and sediment across seven sites along the Palar River estuary in southeast India, finding that fiber-shaped high-density polyethylene microplastics dominate, likely originating from fishing gear and industrial discharge. The study establishes a contamination baseline for a multi-source river system, highlighting how riverine environments serve as highways transporting plastic pollution from inland industrial and agricultural sources into coastal marine ecosystems.
Distribution of Microplastics in the Sediment Profiles of River Benue, North Central Nigeria
AI summary Read the abstract
The first microplastic survey of River Benue sediments in Nigeria found pollution at levels qualifying as contaminated, with higher concentrations on the southern bank near population centers, and polystyrene and PET as the dominant identified polymers. The study fills a critical data gap in African freshwater monitoring and shows that microplastic pollution is not confined to wealthier or more industrialized regions.
Microplastics in Indian Brackish Water Lagoon: Occurrence and Distribution in the Chilika Lake
AI summary Read the abstract
Researchers surveyed microplastic pollution in Chilika Lake, one of the world's largest brackish water lagoons in India, finding microplastics present in both water and sediment samples across the lake — raising concerns about contamination of a critical ecological and fisheries habitat that millions of people depend on.
