Preliminary investigation of the spatio-seasonal distribution of microplastics in the surface water of River Benue, North Central Nigeria

This study provides the first comprehensive assessment of microplastic pollution in Nigeria's River Benue, collecting surface water samples during both rainy and dry seasons and analyzing them with FTIR spectroscopy. Microplastic abundance was higher during the dry season, with particle sizes of 1.5–3 mm most common — a range that raises particular concern because fish can easily ingest them. Risk indices indicated moderate to severe pollution at multiple sites, correlating with commerce, transportation, and waste disposal activities along the riverbanks. These baseline findings are crucial for developing water management strategies in an understudied African river system.

Assessment of Microplastic Contamination in Surface Water of River Benue in Makurdi Metropolis, Benue State, Nigeria

Researchers sampled surface water at five sites along the Benue River in Makurdi, Nigeria, and found microplastic contamination at all locations, with concentrations varying depending on proximity to urban and industrial activities such as markets, rice mills, and bridges. FTIR analysis identified the polymer types present, and the work provides baseline contamination data for a major West African river that has received little prior attention. The findings highlight that microplastic pollution in African freshwater systems is real and measurable, and calls for expanded monitoring across the continent.

Assessment of Microplastic Pollution in Selected Water Bodies in Rivers State, Nigeria

Researchers assessed microplastic pollution in water, sediment, and fish samples from two water bodies in Rivers State, Nigeria — the freshwater New Calabar River and the estuarine Bonny River — detecting polyethylene, PET, polystyrene, and polypropylene along with plasticizers including dioctyl terephthalates and polybrominated diphenyl ether in all sample types. FTIR analysis confirmed polystyrene-type polymers, and the authors called for greater public awareness and measures to prevent macroplastic dumping in these waterways.
