ClearAssessment of Microplastic Pollution in Surface Water and Sediments of Otammiri River, Imo State, Nigeria

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.

The study found microplastics present in both species, highlighting the riverine pollution burden and potential for human dietary exposure through fish consumption.
Occurrence and Health Implications of Heavy Metals in Microplastics from Otuoke Surface Waters
This study investigated the occurrence of heavy metals associated with microplastics in surface waters in Otuoke, Nigeria, finding that MPs adsorb and concentrate toxic metals and may serve as vectors for metal exposure in local communities consuming fish. (Duplicate record of ID 11006.)
