ABSTRACT The present study was conducted to characterised and assess heavy metal contamination in food through milling process and their health implications. Grinding plate made from Ghana, India and Nigeria purchased from the Ghanaian open market were used for this work. Maize from the same farm was milled into flour using the three grinding plates inserted into three different corn milling machines operating on commercial bases. The first grinding was done immediately after the insertion o...
ABSTRACT The study is on the characterization and depositional environment of upper Cretaceous sediments exposed at the Ihube-Ikpankwu Axis, Okigwe. The results of field and laboratory studies on selected samples of the study area show that the sediments in the study area are fine to medium grained, with an average mean size of 1.808Φ. The standard deviation (dispersion sorting) values range from 1.38 – 2.48 i.e. poorly to moderately sorted with an average value of 1.805Φ. The studied s...
ABSTRACT Environmental degradation and the unsustainable exploitation of non-renewable resources continue to increase to satisfy socio-economic demands which call on a National Development Agenda to make use of Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) as sustainability tools imperative. The use of these tools is to balance environmental and economic sustainability with institutional capacity building, and social cohesion to direct the sustainable man...
ABSTRACT Groundwater resource development in Ghana contributes substantially to the socioeconomic development of Ghana. Utilization of water for domestic, irrigation and industrial purposes for about 80% of the rural – urban population in the Kwabenya Community within the Ga East Municipality are primarily dependent on existing groundwater resources. However, groundwater potential is under serious threat and run a high risk of pollution by agrochemicals, municipal, industrial, and domestic ...
ABSTRACT Hospitals effluent often contain chemical compounds which may have negative impact on the environment and human health if not properly treated. Investigations were conducted to determine the bacteriological and physico-chemical qualities of effluent discharged from University of Ghana hospital into the environment and its effects on agricultural soils and vegetables. Water and soil quality analyses of some physico-chemical and bacteriological variables were carried out on effluent sa...
ABSTRACT “Burkina”, a popular fermented milk beverage containing fermented millet agglomerates, is consumed in West Africa. Consumer behaviour towards “Burkina”, perceptions on its safety and potential for causing food borne illness, affects the distribution and sales of the product. Tiger nut, an underutilized crop in West Africa, with a rich nutty taste and unique mouthfeel has been incorporated into formulations for fermented milk products such as yoghurt, but not “Burkina”. Th...
Abstract The present study is an attempt to elucidate the effect of biodiesel emission particles (BEP) on some antioxidant enzymes of selected tissues of rats. Rats were exposed to emission particles (EP) of biodiesel blended with fuel diesel at 100BD, 75BD, 50BD and 25BD as well as fuel diesel (FD) over a period of ten days. Enzyme assays were conducted for superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX) and reduced glutathione (GSH) in the liver, lungs, ...
ABSTRACT This research work was aimed at assessing the quality management system and radiation protection of patients of four mammography facilities in Ethiopia. A questionnaire was designed to collect data to assess the status of the quality management systems at the facilities. Quality control measurements were done to verify whether the mammography machines were performing self- consistently compatible with National and International standards. The status of patient protection was evaluate...
ABSTRACT The two-spotted spider mite Tetranychus urticae is a pest of several plants including vegetables, fruits, ornamentals and field crops. Damage done to the host plant can cause leaf and fruit loss, complete defoliation and death of the host plant. They are mostly managed by the use of acaricides. Acaricides resistance has been reported in several countries, this is due to the fact that T. urticae fully becomes resistant to an insecticide after two to four years of use. The present stud...
ABSTRACT As a result of the increasing demand for the use of mosquito coils in Ghana, as a means of personal protection against Anopheles gambiae sensu lato, it was important to evaluate the effectiveness of three selected mosquito coils under field conditions and also determine the resistance status of Anopheles gambiae sensu stricto against pyrethroid-based mosquito coils. Three bands of pyrethroid-based mosquito coils; Angel Jumbo coil®, Lord Insecticide antimosquito coils® and Heaven J...
ABSTRACT The purpose of this study was to investigate the apprenticeship system of fifty seamstresses and fifty apprentices from Achimota, Legon and Madina neighbourhoods of Accra. A stratified sampling technique was used to select the respondents from these neighbourhoods. The respondents were interviewed by the researcher, using two separate structured questionnaires: One for the seamstresses and the other for the apprentices. A non-obtrusive observational guide was also used to evaluate te...
ABSTRACT The research was conducted to assess the levels of contamination of heavy metal in topsoil at auto-workshops in Accra, to determine the anthropogenic and crustal contributions and the human health risk associated with them. Soil samples collected from four selected auto-workshops were analysed using Atomic Absorption Spectrometer. Eleven (11) elements: Co, Fe, Cu, Mn, Cr, As, Hg, Zn, Pb, Ni and Cd were identified in each sample collected from the auto-workshops. Pollution indices; co...
ABSTRACT Indiscriminate use of insecticides in controlling insect pests of agricultural crops has been implicated in the development of resistance in disease vectors such as the Anopheles gambiae s.l Giles (Diptera: Culicidae) populations that breed within farming areas. Since vector control strategies are insecticide based, it is important to study insecticide resistance in farming areas such as irrigation sites where vectors are breeding. The aim of the study was to investigate insecticide ...
ABSTRACT Developmental and Educational psychologists continually set research-based quality standards in Early Childhood Education. However, not much is known on the level of quality and the practices in the early childhood centers in Ghana. This research explored the concepts of quality and best practices, internationally known as Developmentally Appropriate Practices (DAP), in four (4) early childhood settings in Haatso, a cosmopolitan suburb in the Ga-East District of Greater Accra, Ghana...
ABSTRACT This study assessed the impact of charcoal production on soil properties, vegetation and the perception of charcoal producers on the environmental impacts of their activities in the Central Gonja District of the Northern Region, Ghana. Data acquired suggest significant differences in the proportions (or fractions) of clay and sand in soils sampled within 0-30 cm depth at sites of charcoal production referred to simply (as burnt sites) and sites with no observable indications of char...
