Characterization of Microplastics from Otammiri River Imo State, Nigeria
AI summary Read the abstract
Researchers characterized microplastics from Otammiri River in Imo State, Nigeria using NOAA surface water trawling protocols, finding particles ranging from 0.3 to 5 mm that were resistant to wet oxidation, floated in 5M NaCl solution, and were identified by FTIR spectroscopy.
This study characterized microplastics from Otammiri River, Imo state, Nigeria. The study was carried out according to the National Oceanic and Atmospheric Administration (NOAA) protocol for surface water trawling for microplastics. The microplastics characterized were at the range of 0.3 mm to 5mm which were resistance to wet oxidation and exhibited flotation in a 5M NaCl. Fourier-transform infrared spectroscopy (FTIR) examination was used to characterize the microplastics for identification. FTIR results revealed that polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET) polystyrene (PS), and polyurethane were the predominant polymers (microplastics) found across Otammiri river.

AI summary Read the abstract
Researchers examined microplastic contamination in surface water and two fish species (Notopterus afer and Heterobranchus bidorsalis) from Ovia River in Southern Nigeria, using SEM, FTIR, and EDX to characterize particle size distribution, polymer composition, and elemental contamination. The study provides baseline data on microplastic pollution in a West African river system and documents uptake of plastic particles by commercially important fish species.
Assessment of Microplastic Contamination in Surface Water of River Benue in Makurdi Metropolis, Benue State, Nigeria
AI summary Read the abstract
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.
