Assessment of fishes, sediment and water from some inland rivers across the six geopolitical zones in Nigeria for microplastics.

In Nigeria, limited research has been conducted on Microplastics (MPs) in inland rivers, necessitating a comprehensive assessment to understand the extent of contamination. This study aimed to assess the abundance, distribution, and composition of MPs in fishes, sediment, and water from inland rivers across Nigeria's six geopolitical zones. Samples were collected from selected rivers in each geopolitical zone (Rivers Yauri, Benue, Argungu, Jamare, Ogun, Ethiope and Orashi).

COVID-19 vaccines uptake: Public knowledge, awareness, perception and acceptance among adult Africans.

Introduction: The willingness of Africa's population to patronise the COVID-19 vaccines is critical to the efficiency of national immunisation programmes. This study surveys the views of adult African inhabitants toward vaccination and the possibility of participating or not participating in governments' efforts to get citizens vaccinated.

Method: A cross-sectional online survey of adult Africans was undertaken from December 2020 to March 2021.

Aerobic microbe community and necrophagous insects associated with decomposition of pig carrion poisoned with lead.

This study investigated the effects of pig feed contaminated with lead (Pb) on the decomposition rate of pig carrion, identified the aerobic microorganisms and necrophagous insects associated with decomposing pig (Sus scrofa) carrion (above ground), and explored their potential use in the determination of post-mortem interval (PMI). The study profiled the decomposition of Sus scrofa carrion over a period of 40 days to record the effects of lead during decomposition. Fungi were identified by sub-culturing on prepared solidified potato dextrose agar and microbial identification was carried out using biochemical characterization.

Biodegradation of Pollutants in Waste Water from Pharmaceutical, Textile and Local Dye Effluent in Lagos, Nigeria.

Background: Discharged effluents from industry have been responsible for the deterioration of the aquatic environment in many parts of the world, especially in developing countries. Increasing industrialization and urbanization have resulted in the discharge of large amounts of waste into the environment, resulting in high pollution loads. Utilization of microbes such as fungi and bacteria have been used for pollution degradation.

Histopathological alterations, biochemical responses and acetylcholinesterase levels in Clarias gariepinus as biomarkers of exposure to organophosphates pesticides.

Organophosphate pesticides, commonly used in large scale farming, have been found to be major contaminants in aquatic environment. Clarias gariepinus was exposed to acute and sublethal concentrations of phostoxin and DD Force to evaluate single and joint action toxicity of the organophosphates. Effects of phostoxin and DD force on antioxidant enzymes, fish organs and acetylcholinesterase levels in fingerlings and juveniles of C.
