Microplastics Pollution Assessment in the Surface Water and Sediment of River Niger, Lokoja, Nigeria

Pollution from microplastics (MP) is now considered to be a major global environmental concern, and Nigeria is not an exception. In Nigeria, the River Niger is an essential resource that is used for agriculture, transportation, and fishing. The purpose of this study was to evaluate MPs contamination in Nigeria's Niger River, Lokoja, Kogi State: The sampling was carried out in 2024 between March and June. Following digestion with 10% KOH, density flotation with NaCl, and filtration, the water and sediment were examined.

Concentrations, Ecological and Health Risk Assessment of Heavy Metals in Surface Water and Sediments of Ogun River in Owode Onirin,

Industrial processes, including scrap yards, can contaminate surface waters with heavy metals, posing a risk to aquatic habitat and human health. Thus, the concentrations, ecological and health risks of heavy metals in surface water and sediment of the Ogun River in Lagos was investigated. Surface water and sediments collected from the Ogun River were analyzed for some physicochemical parameters and heavy metals using standard procedures.

Polycyclic aromatic hydrocarbon (PAHs) and polychlorinated biphenyl (PCBs) profiles of sediments from Falcorp mangrove swamp, Warri, Delta State

The Falcorp mangrove swamp has and is still been exposed to various forms of anthropogenic polluting activities which include; Vandalization of oil pipelines which transverse sections of the swamp. The PAHs and PCBs profile of swamp sediments was investigated. The sediments were subjected to routine PAH and PCB analyses which included; extraction, use of sonicator, GC-ECD and GC-FID analysis. The data were subjected to statistical and multivariate analysis using Microsoft Excel, SPSS version 16.0 and PAST respectively.
