Abstract:

Heavy metal levels in Elemi and Ogbese Rivers surpass WHO standards, endangering community health. Limited awareness, linked to education gaps, increases exposure risks. Urgent action is needed to improve water safety and public health awareness. Hence, this study investigated water usage trends and heavy metal contamination in Elemi and Ogbese Rivers in Ado-Ekiti, Nigeria. Data on demographic characteristics were collected through a guided questionnaire administered to 150 adults each, aged 18-55, from the two communities. Metals (Hg, Cr, Pb, Zn, Co, Cd) analyses in the water samples were car

Abstract:

The movement of sediment such as sand, silt or gravel by flowing water is of interest to a wide range of engineering disciplines. This study is aimed at developing models, which can be used to predict the magnitude and levels of sediment concentration in Ogbese and Owena Rivers in Ondo State S.W. Nigeria for engineering design purposes. Data were collected from field investigations conducted at the respective sampling stations on the two rivers. The live bed concept used was derived from Liu – Hwang (1954) resistance equations and that of Einstein-Brown (1981) sediment transport concept. The p

Abstract:

Microbial contamination of food is the main obstacle of ensuring food safety. For this, it’s paramount to ascertain the safety of fish caught in the major waters in Ado Ekiti( Water works and Ogbese river). 22 (11 each)fish sample was randomly caught from both rivers in Ado Ekiti Metropolis.The research was conducted in May,2021. After standard microbiological and biochemical Test. The total bacteria count (TBC) for all the fish samples ranged between 0.46 x 104 and 0.95 x 104 cfu/g . Out of the 22 fish samples analyses for TBC, a sample from Water works dam had the highest number of bacteria

Abstract:

Increased rainfall amounts are projected in the humid southern parts of Nigeria due to climate change. The consequence of higher rainfall in future years would result to higher peak runoffs and flood stages in streams in these parts. The focus of this study is to simulate peak runoff at the outlet of Ogbese river watershed for future years of 2030, 2040, 2050 and 2060. Local twenty years (2000-2019) historical rainfall depths were used to statically downscale General Circulation Model outputs in the future for RCP 4.5 climate scenario. Downscaled rainfall depths were inputted in HEC-HMS model

Abstract:

A study on the transmission of visible light (400 nm-800 nm) in some selected natural water bodies of Southwest Nigeria was carried out via spectroscopy, and their salinity, total dissolved solids, and electrical conductivity were obtained. Samples of ten selected water bodies comprising rivers, lagoons, and the Atlantic Ocean were taken namely: River Ala, River Ogbese, River Kinira, River Apake, River Odo-Oru, River Odo-Eran, Epe Lagoon, Lagos Lagoon (Lekki Phase 1), Lagos Lagoon (Victoria Island) and the Atlantic Ocean. The absorption of light in them was measured using a spectrophotometer.

Abstract:

The increase in multidrug resistance pathogenic bacteria and decrease in efficiency of existing antibiotics is a serious global health concern which call for development of new alternative medicine and continuous research for new classes of antimicrobial agents that can be effective in destroying these multidrug resistant pathogens without or with minimal side effect and at an affordable cost. N. lotus has been reported to possess some amount of phytochemicals such as phenols, tannins, saponins, steroids, proanthocyanidins and flavanols which may serve as an effective antimicrobial agent.

The silver catfish Chrysichthys nigrodigitatus is of economic importance in sub-sahara Africa. In Ogbese town, and its environs, it constitutes a means of income and food for fisherfolks and community members. Hence, this study was undertaken to assess health status of Chrysichthys nigrodigitatus using haematology and histological assessment of the fish specie due to the anthropogenic activities that takes place around the river body. A total 120 live juvenile fish samples of C. nigrodigitatus were collected around shallow habitats of Ogbese River by the assistance of fisherfolks using fish ca

Abstract:

Investigations on the accumulation of heavy metals in water and sediments of river Ogbese were carried out between December 2010 and February 2011 using Atomic Absorption Spectrophotometer. Etheria elliptica a sessile organism was also used to determine the concentration of heavy metal in the aquatic environmental. In water, Cu had the highest concentration (0.55 – 0.13 mg/l ±0.1) while in sediments, the highest value obtained was in Fe (1.46-3.89mg/l±0.27). The minimum concentrations recorded were in Pb; which was below detectable level. The result also revealed that the shell accumulate more

Abstract:

Floodplains are very important for agriculture, since it allows planting of arable crops throughout the year. In order to asses pollution levels of the floodplains due to contamination from flooding,soil samples were collected from six locations across each of the floodplain of Owena river, Ogbese river and Ala river in Ondo State. The study investigated the chemical speciation of Cd, Cu, Ni and Zn in the alluvial soil matrix due to deposition of metals as result of inundation of the floodplains. The heavy metals were quantified using Atomic Absorbtion Spectrophotometer. The concentration of h

Floodplains are agro zone for most vegetables worldwide and incidentally they are sinks for pollutants especially heavy metals. The total concentration of metals is not a good indicator of mobility/bioavailability or potential risk assessment hence more preferred elemental geochemical environment. This study is therefore aimed at investigating the geochemical environment of some potentially harmful elements in the agro zone flood plains of some rivers in Ekiti State, Southwest Nigeria.
