Assessment of Microplastic Pollution in Surface Water and Sediments of Otammiri River, Imo State, Nigeria
AI summary Read the abstract
Researchers assessed microplastic pollution in the surface water and sediments of Otammiri River, characterizing the abundance, morphology, polymer types, and spatial distribution of microplastics to evaluate contamination levels and ecological risks in this Nigerian freshwater system.
This study analyzed the physicochemical and heavy metal status and also quantified microplastics from Otammiri River, Imo state, Nigeria. The physicochemical and heavy metal analysis were carried out using procedures of Federal Environmental Protection Agency. The quantification of the microplastics from Otammiri River was carried out according to the National Oceanic and Atmospheric Administration (NOAA) protocol for surface water trawling for microplastics. The microplastics quantified in this study were at the range of 0.3 mm to 5mm that were resistance to wet oxidation and exhibited flotation in a 5M NaCl. The result of the physicochemical parameters showed that the parameters were within the Federal Ministry of Environment (FMEV) permissible limits with exception to lead and mercury. The microplastics concentrations at the surface water of Otammiri River was between 0.12 g to 2.50 g and in sediments samples, between 0.01 g to 1.37 g.

Microplastic particles in river sediments and water of southwestern Nigeria: insights on the occurrence, seasonal distribution, composition, and source apportionment
AI summary Read the abstract
Researchers surveyed microplastic contamination in river water and sediments across southwestern Nigeria, providing some of the first baseline data for the region. They found microplastics at every sampling site, with fibers and fragments being the most common forms, and concentrations varying by season and location. The study points to urban runoff, agricultural activities, and inadequate waste management as the primary sources of this pollution.
