Determination of Subsurface Sewage Contamination of Rocks and Water using 2-D Resistivity Imaging: A Niger delta University Teaching Hospital Case Study, Bayelsa state Southern Nigeria.

2024-02-11T08:21:22+00:00

Septic tanks as used in the management of sewage systems may result to both surface and/or subsurface (groundwater) pollution. While remediation and repairs of surface sewage spillage in septic tanks is feasible, the reverse is the case with subsurface pollution of porous media through sewage seepages. 2 D Electrical Resistivity Imaging (ERT) was used to determine the nature of sewage contamination of subsurface rocks in the premises of the Niger Delta University Teaching Hospital (NDUTH) Okolobiri in Bayelsa State, Southern Nigeria. It was observed that in the presence of contaminant fluids, geoelectrical resistivity signatures behave anomalously in most cases being more conductive than the clean rock/fluid system. Also, that contaminant fluid, in the course of time, finds its way into groundwater to alter the electrical and chemical properties of pristine rock/fluid as seen in this investigation. The observed subsurface contaminant (leachate) migrate in the direction of groundwater flow and decreases in concentration away from the source (septic tank) which in the current study is in the North South direction as represented in the 2 D resistivity contouring of the three (3) geoelectrical profiles in this report.

Effects of Some Herbal Cosmetics on Sex Hormones of Rabbits

2024-02-11T08:21:24+00:00

Heavy metals have been observed as competitor for receptor sites in hormones thereby resulting in infertility problems. Herbal cosmetics have been observed to contain heavy metals which interfere with the receptor sites of hormones. Three herbal cosmetics sold in Port-Harcourt were evaluated for heavy metals and rabbits exposed to them for 30 -90days. The aim is to determine the effect of heavy metals on the sex hormones of the rabbits. Three herbal oil namely All things natural (Emi herbal oil), Kakiva (Kakiva herbal oil) and Amal (botanical herbal oil) as well as forty –eight rabbits were purchase from a market in and animal house in Port Harcourt respectively. The rabbits were exposed to the oil for 30, 60 and 90 days and scarified for blood samples. The sex hormones of the rabbits evaluated using standard methods. Data were analyzed using statistical package for social sciences (SPSS) to compare means. There were no significant differences in the sex hormones in 30days and 60days. However, there was a significantly lowered progesterone and estrogen after exposure 90days. It is therefore pertinent to conclude that herbal cosmetics contain heavy metals which may alter the sex hormones pattern which leads to luteal phase dysfunction.

Thermal Analysis of a Serpentine tube Absorber Plate Solar Collector System using Experimental and CFD Simulation

2024-02-11T08:21:25+00:00

Solar energy is a promising renewable energy source that can be harnessed through various technologies, including solar collectors. The objective was to evaluate the system's thermal performance and understand the heat transfer mechanisms involved. Experimental analysis was carried out using locally fabricated flat plate solar collector setup, considering solar radiation data collected from the National Centre of Energy and Environment (NCEE), Benin City, Edo State, Nigeria. Using the same data set, ANSYS fluent 2018 version was employed for thermal simulation analysis to determine the flow within a serpentine tube, temperature and heat distribution across the flat plate as well as water temperature at the tube exit point. The model was developed to predict thermal behaviour of the system which in the process had considered the principles and laws of thermodynamics, while also solving the equations of continuity, momentum and energy. Water was assumed to be incompressible and flowing continuously while the flow was steady in nature and characterized by laminar. A significant correlation between the experimental and Computational Fluid Dynamics (CFD) simulated results was observed, as maximum experimental and CFD absorber plate temperatures of 368.64 and 372.98 k, serpentine tube water temperatures of 329.14 and 330.45 k and water outlet temperatures at tube exit of 330 and 329 k were obtained. The minimal temperature differential indicated an improved heat transfer absorber plate solar collector system. During the analysis, the physical and thermal properties of the absorber plate, tube and water were independent of the temperature. Heat loss from the base of the absorber plate bottom and the serpentine tube occurred via convection and depended on wind speed. Hence, adoption of ANSYS fluent is an effective CFD tool that can appropriately simulate thermally related problems in serpentine tube absorber plate solar collector system. The results obtained from both approaches were compared and analysed to validate the CFD model and gain insights into the system's performance.

Hydrogeochemistry of the Geologic Profiles of Enwan and Environs, Akoko Edo, South South Nigeria

2024-02-11T08:21:31+00:00

Hydrogeochemical investigation as well as petrographic examination of rock samples was carried out in Enwan and environs, in Akoko Edo, South South Nigeria. Ten (10) water samples and two (2) rock samples were collected from study area for analyses. All of the samples collected were subjected to geochemical and petrographic analysis respectively, Physical parameters such as pH, TDS, Electrical conductivity and temperature were measured in situ using standard equipments and the analysis for the chemical parameters was carried out with Atomic Absorption Spectrometer (AAS). The concentration of metals in the samples was determine through geochemical analysis the correlation of physical and chemical parameters. Ca2+, Mg2+, K+, Na2+, Fe2+ and Cu2+ were the cations analyzed for while the anions included HCO3, NO3 and Cl . The results were compared with the world Health Organization (WHO) and Nigerian Industrial Standard (NIS) standards to determine the quality of the groundwater. ENW4 had the relatively highest calcium and magnesium ions concentration. ENW3 and ENW4 have the relatively highest chloride ion concentration, but all the samples have extremely high chloride concentration. The anthropogenic sources from which the high concentration
of these parameters such as Chloride, Iron, Electrical conductivity and pH
were found could either be as a result of the human activit ies in this study
area or weathering of rock forming minerals such as Biotite, Quartz,
plagioclase. The source of contamination of Iron in the groundwater is from
weathering of surrounding rocks and subsequent leaching into the aquifer.
During weathering, because feldspars are not resistant to weathering unlike
quartz that are very resistant, it gives off Na + and K + which are then
washed down into the groundwater through percolation. The Piper plot
shows that the all the samples belong in the Ca 2+ Mg 2+ Cl hydrochemical
facies which results to an area of hardness because of the magnesium and
chloride ions.
