Geophysical and hydro-chemical investigation of the area around a waste dump site in Ile-Ife, southwest Nigeria

An integrated geophysical and hydro-chemical investigation was carried out in the area around the Stadium-Apollo Market waste dump located in Igboya area of Ile-Ife. It was with the aim of determining the geoelectric characteristics and groundwater chemistry which were used in delineating the subsurface sequence and evaluating the possible pollution of groundwater in the area. Eight Vertical Electrical Sounding (VES) stations were occupied along two traverse lines trending North-South and East-West directions. Dipole-Dipole profilings were also carried out along same traverses. Eight water samples were collected from hand dug wells and analyzed for some chemical elements such as total acidity, major ions (Na+, K+, Cl-, Mg2+, Ca2+), NO3- and heavy metals (Cd, Cu, Fe, Hg, and Pb). Results of the investigation indicate that a maximum of four subsurface layers- the top soil, clay/sandy clay unit, the weathered layer and the basement bedrock exist in the area. The weathered layer constitutes the main aquifer unit with thicknesses of between 7 and 38 m. From the 2-D resistivity structures, contaminant plumes characterized by relatively low resistivity values (< 150 ohm-m) were identified down to depth of about 40 m in some places. Hydro-chemical results showed that the total acidity and concentration of Na+ Cl- and heavy metals (Cd, Cu, Fe, Hg and Pb) in wells closest to and down slope of the waste dump (total acidity 5.1-10.0 mg/l; Na+ 8.92-11.07 mg/l; Cl- 127.62-297.78 mg/l; Cd, 0.006-0.009 mg/l; Cu, 0.330-1.840 mg/l; Fe, 2.300-4.600 mg/l; Hg, 1.247 mg/l and Pb, 0.260 Mg/l) are higher than concentrations in distant wells, and most of them (Cl-, Cd, Cu, Fe, Hg, and Pb) exceeded national and international drinking water quality standards. It can be concluded that the groundwater in the area had been contaminated and the plume had migrated to a significant depth.KEYWORDS: Geophysical, Hydro-chemical, Waste Dump, Groundwater Quality, Pollutio

Aspects Affecting Women's Involvement In Political Leadership: A Case Study Of The University Of Education, Winneba, Ghana

Women's involvement in political leadership is crucial to ensure gender equality and meet sustainable development and international integration requirements. Although many measures have been developed domestically and internationally to enable women to be involved in political leadership, women's involvement in this area still needs to be improved in Ghana and around the globe. However, women's participation in political leadership has increased relatively but not significantly. The study investigates the aspects that affect women's participation in political leadership. The study assesses the influence of demographic, economic, cultural and gender-based electoral perception on women's participation in political leadership.Economic aspects such as mobility, income, and resources were examined as cultural aspects such as women's priorities and if the cultural aspect supports women's entry into politics. The study was conducted through a descriptive survey with a quantitative approach. Data was collected using online questionnaires and responses from 70 University of Education, Winneba participants. Data were analysed using percentage and frequency distribution techniques using the JASP 6.0 version. Data collected was presented in tables in frequencies and percentages. Results showed a significant association between women's involvement in political leadership and demographic and cultural aspects. The research has theoretical and practical implications for future studies on women and politics in the country

Assessment of Surface and Groundwater Quality of the Akure Metropolis, Southwestern Nigeria.

Hydrochemical analysis was carried out on surface and groundwater samples collected from Akure metropolis with a view to determining their quality. Hydrochemical data on groundwater samples from fifty six (56) boreholes were sourced from the Ondo State Water Corporation. Twenty five (25) surface water samples from streams and rivers in the study area were collected and analyzed using standard analytical techniques. The analyzed physical parameters include colour, odour, turbidity, conductivity and chemical properties such as pH, dissolved solid, hardness, cations, anions and heavy metals. All the groundwater samples were colourless, odourless and tasteless. Some surface water samples were coloured and turbid in appearance while some had objectionable odour. Although the NO3- concentration levels in both surface and groundwater samples were generally below the WHO threshold value of 10 mgl-1, relatively high concentration range (2.5-6.0 mgl-1) was recorded within the city centre indicating some level of pollution from cumulative anthropogenetic activities. Only few surface water samples contain Pb while Mn was identified in some surface and groundwater samples. The elevated Pb concentration levels (0.41-3.41 mgl-1) and relatively high Mn concentration levels (up to 2.18 mgl-1) (both much higher than the WHO and NIS thresholds) in some surface water samples was an indication of heavy metal pollution. Conductivity values of the groundwater samples generally ranged from 42.0 – 1400.0 µScm-1.  Only surface water sample 17 was moderately saline while other surface water samples were of freshwater type. Based on TDS values, all the groundwater and surface water samples were of freshwater type (TDS &lt; 1000 mgl-1). Keywords: Physico-chemical Analysis, Surface/Groundwater, Quality, Akure Metropolis

Velocity-Porosity relationship in clastic formations – a case study from some parts of Niger Delta, Nigeria

Velocity-Porosity relationship in some parts of Niger Delta was studiesd with a view to establish the velocity-porosity relationship and the generalized equation(s) that best describe this relationship in clastic formations. Five wireline logs were acquired for the study. Neutron porosity log data was converted to synthetic velocity (VTA) using time-average equation of Wyllie (1956), and the sonic porosity log was converted to sonic velocity (Vsonic). The results were presented as velocity-porosity crossplots with the trend line equations and the coefficient of correlation. The results give a distinct inverse velocity-porosity relationship; i.e. velocity decreasing with increasing porosity. The velocity-porosity relationships established from both sonic log (Vsonic) and time-average formulation are best described by polynomial fitting of 2nd order. Two generalized equations of high coefficient of correlation, which can be used to calculate compressional velocity (Vp) from porosity values in clastic formations, were established from these relationship.
