ABSTRACT Maize is consumed by over 95% of the Ghanaian populace and the practice of using atrazine, lindane and other organochlorine pesticides in its production has raised concerns about potential adverse effects on human health and the environment. A field survey was conducted in this study to assess farmers‟ knowledge of safe handling and use of these chemicals as well as toxicity awareness and symptoms among farmers and traders. Residues of the pesticides in maize samples as well as th...
ABSTRACT Sandcrete is widely used as building material. Its properties greatly depend on the properties and proportions of its constituents. The main binder material to produce sandcrete is the Portland cement. The uncertainty about future availability of commonly used Portland materials concomitantly with the environmental problems such as greenhouse gases emissions and high cost of clinker consumption are highlighting the need of identifying other materials for the construction industry, w...
ABSTRACT Non-destructive testing (NDT) is a group of inspection techniques used to detect, locate and assess flaws in materials without affecting, in any way, their continued usefulness or serviceability. NDT has the ability to inspect castings, weldments and measure wall thicknesses in an accurate and comprehensive manner. In this study, NDT techniques were used to inspect large diameter pipes that are used for transporting substance in the form of liquids and gases in industries. The aim o...
Abstract The nature of socio-economic transactions taking place in Lagos Island every day makes solid waste management challenges more acute. These transactions generate large volume of waste which has become an environmental challenge because of poor refuse management strategies which do not match the rate of refuse generation. This study examines the underlying factors militating against efficient control of solid waste collection in Lagos Island by applying geographic information systems a...
ABSTRACT Though the Persons of Disability Act 715 calls for the provision of an accessible environment, attention on the mobility needs of commuters with disability has focused on persons with disability access to public buildings like library without paying attention to the walking environment connecting the homes of commuters to these public facilities. This study was carried out to examine the road transport infrastructure and mobility needs of students with physical disability in UCC. Sp...
ABSTRACT Ethnobotanical and ecological studies were carried out to take inventory of the species used by the inhabitants surrounding the Subri River Forest Reserve for reproductive health care and to assess the ecological status ofwoody plant species ofthis reserve. The study was carried out between November 2005 and December 2006. Medical ethnobotanical knowledge was gathered from 80 inhabitants in 25 , , communities using questionnaires. Reproductive health conditions were categorized into...
ABSTRACT This research was carried out to investigate the species variability within Afrotropical stingless bees of the genus Hypotrigona (Cockerell) in three districts in the Central Region of Ghana. Hypotrigona species are common visitors to flowering plants in the tropics and subtropics. Structurally, the three known Afrotropical Hypotrigona species are very similar and pose difficulty in accurately identifying existing species. In view of this taxonomic impediment, this present study aime...
ABSTRACT Ghana is in the process of converting its fuel from Highly Enriched Uranium (HEU) to Lowly Enriched Uranium (LEU) even though the HEU fuel is not fully spent, thus the handling of the irradiated fuel is in the offing. Irradiated fuel consists of radioactive fission and activation products generated in the nuclear fuel which are hazardous to personnel, environment and the public. As a result, the knowledge of the dose rate will aid in safe guarding the process of core conversion. Two ...
ABSTRACT Shales from the Paleoproterozoic Birimian Supergroup in parts of the WaLawra Belt, Northwestern Ghana, were analyzed for their major and trace element contents using ICP-MS and ICP-AES with the main aim of establishing the geochemical characteristics of the shales and inferring their provenance. On the whole twenty-two (22) samples of the shale was collected for analysis. The studied shales were compared to Early Proterozoic crust (EPC) and Post Archean Australian Shales (PAAS), and ...
ABSTRACT Livestock are vital to subsistence and economic development, providing food, income, employment, manure and savings for Sub-Saharan African farmers. Diseases and arthropod ectoparasite infestations often impact negatively on livestock production and productivity. This study assessed the effects of arthropod ectoparasite infestations on the productivity of three ruminant (cattle, sheep and goats) livestock species in three Districts of Southern Ghana around the Volta River. A total of...

ABSTRACT This research was carried out to investigate the origin of salinity in the unsaturated soil zone with emphasis on chloride profile and stale isotopes in the Ekumfi Akwakrom and Ekumfi Asokwa in Mankessim Municipality of the Central Region of Ghana, which has been reported to have high saline groundwaters. A total of 159 samples were analysed, which comprises: fifty – six (56) rainwater samples, fifty – three (53) soil from the unsaturated zone, two (2) groundwaters, forty – two...
Municipal solid waste landfill is an important part of the urban infrastructure that ensures the protection of environment and human health. Landfill selection problem for municipal solid waste involves many factors, criteria and regulations. The aim of this study is to access suitable site for an engineered solid waste landfill, ·with specific objectives of site determination based on UNEP criteria and carrying out both geophysical and geotechnical evaluation of the site. The study are...
ABSTRACT Malawi became an IAEA member state in 2006 and developed the Atomic Energy Act and Regulations in 2011 and 2012 respectively. However, regulatory authority and personnel monitoring services have not yet been established. As such, hospitals operating radiological services in Malawi do not have personnel monitoring programme. This study aimed at developing the personnel radiation monitoring program for three hospitals in Malawi namely; Kamuzu Central Hospital, Bwaila Hospital, and Mten...
ABSTRACT The production of cassava (Manihot esculenta Crantz) under rain-fed conditions at the Kwabenya-Atomic area in the coastal savannah environment is constrained by low and erratic rainfall events. Improving cassava production in the area requires the use of cassava varieties which are efficient in the use of limited soil moisture. The objective of the study was to evaluate the response of two early maturing cassava varieties to three (3) planting densities to TDM, RY, and WUE. The actua...
