ABSTRACT Melia volkensii (Melia) is an indigenous tree species belonging to the plant family Meliaceae. In Kenya, the tree is commonly known as “Mukau”. Melia grows naturally in the arid and semi-arid zone of Tanzania, Ethiopia, Somalia, and Kenya. It’s highly valued for its timber which is termite resistant and so imperatively durable. Despite its popularity, its domestication efforts have been minimal, as a result of poor access to quality planting material and lack of a comprehensive...
ABSTRACT Rift Valley Fever (RVF) is an emerging viral disease which causes among other problems severe hemorrhagic syndrome, retinitis and meningo-encephalitis in humans. The disease was previously thought to be a disease of animals but it is increasingly developing to be a human health problem. Two human RVF epidemics have previously occurred in Kenya (1997-1997; 2006-2007) each resulting to human deaths. Most RVF outbreaks occur in rural locations where keeping of livestock is the main liv...
ABSTRACT The study was conducted in Gadamoji Division of the hilly Marsabit district, an Arid and Semi-arid area. The aim was to determine the relationship between levels of indoor air pollutants from lighting fuels and respiratory disease incidence. To obtain comparative data, an experimental phase was conducted off the study area. The main objectives were to quantify levels of particulate matter due to lighting fuel emissions, compare results with World Health Organization (WHO) air quality...
ABSTRACT Ground water contamination has become one of the main environmental issues and a challenge to the world population especially in arid and semi-arid areas. The levels of physico-chemical parameters of ground water exceeding the Kenya Bureau of Standards permissible guidelines have resulted to health problems among the water users especially in rural areas of developing countries, where a significant number of serious human health problems have been reported. Kenya being a water scarce...
ABSTRACT Petroleum hydrocarbons (PHCs) are common site contaminants, but they are not generally regulated as hazardous wastes. TPH refers not only to analytical results, but also to environmental and health properties of PHCs. Biodegradation by natural populations of microorganisms represents one of the primary mechanisms by which petroleum and other hydrocarbon pollutants can be removed from the environment and is cheaper than other remediation technologies. The environmental implication as...
ABSTRACT The effect of drilling waste on soil quality was studied at Opukushi Oil field dumpsite in Delta state. The period of sampling and analysis was between June and September 2010. Soil samples from the dump sites and the control site were physicochemical analyzed using Gas Chromatography, Atomic Absorption Spectrophotometer (AAS). Laboratory analysis were conducted according to standard methods. Descriptive statistical analysis was used to obtain range, means, standard errors, as well ...
ABSTRACT Groundwater constitutes a major source of potable water supply foragricultural, industrial and domestic applications. This has led to the increase in the demand for ground water exploitation. Borehole water being an ideal source of portable water supply has been employed to meet this teeming demand. For the purpose of this research, borehole water was adopted as a sample model for the experiment to determine the extent of heavy metal contamination in the ground water of the study ar...
ABSTRACT The supply of food, water, and agricultural resources is fast becoming a difficult issue. This is because the resources are heavily polluted as a result of intensive crude oil spill, and oil related activities in the state. This study focused on the assessment of soil samples from Ogoni, (k- Dere) community. To ascertain the level of pollution that may have occurred. Different parameters were analyzed, namely pH, total petroleum hydrocarbons, nitrate, phosphate, sulphate, zinc, iron...
ABSTRACT A field study was conducted on the Assessment of Ground Water Quality around Abandoned Quarry Ponds near Lower Benue Trough, Nigeria. Water samples were collected using 1liter amber glass bottles each fitted with a screw cap and lined with foil from the four abandoned quarry pits measured fifty meters (50m) (165ft) deep. These were labeled ABP1, ABP2, ABP3, ABP4, while the wells were labeled HDW (hand dug wells) measured eighty meters (80m) (264ft) deep and BH (borehole), measured t...
ABSTRACT The unsanitary condition in which solid waste is temporarily dumped and disposed off has generated environmental concern through pollutions and health hazards. This calls for a need to map out suitable collection points and disposal point for effective and efficient management of solid waste to promote hygienic environment. This study is limited to the new Owerri inside Owerri municipal, Imo State. It focuses on site selection for solid waste collection having considered the existen...
ABSTRACT Information on impacts of subdivision of ranches on land cover is important as it forms vital baseline among others for the detection of impacts of degradation of rangeland and economic resources in the area. This study was conducted between May and November, 2012. The broad objective for the study was to assess the impacts of subdivision of ranches and subsequent land use change on land cover and rangeland resources in the study area. The research employed various data collection me...
ABSTRACT The purpose of this study was to determine the differences in blood pressure, cardiovascular disease bio-chemical risk markers, physical activity and nutrition, between an Urban (US) and Pastoral (PS) sample, in the context of the global epidemiological transition taking place globally causing a shift in mortality and morbidity from communicable diseases to non-communicable diseases. A total of 133 adults from both samples meeting the inclusion criteria, were randomly recruited from...
ABSTRACT As the international community continues to embrace sustainability thinking in decisionmaking, the sugarcane industry too has to adopt and operate within principles of sustainable entrepreneurship. A key input in this evolving paradigm is application of Life Cycle Management approach, whose focus is to determine sustainability concerns at all stages of a product’s life cycle so as to attune business to economic viability, social responsibility and environmental soundness. This stu...
ABSTRACT Soils and cassava tubers in Okigwe auto-mechanic village of Imo state were investigated for presence of Polycyclic Aromatic Hydrocarbons (PAHs) and heavy metals. Six soil samples of 0 - 15 cm and 15 - 30 cm in depth were collected each, at 3 sites, in close proximity to selected automobile workshops. A distant location was used as the control site. Physicochemical properties of soils from this study area were investigated using standard methods, PAHs in the soil and cassava tubers w...
Abstract This study was carried out to examine and determine the impacts of increased human population and the sedentarization of pastoral communities on the land cover and resources of Mt. Marsabit Forest and the immediate surrounding lands. The first objective of this study was to determine the impacts of increased human population and the subsequent land fragmentation and human sedentarization on the resources of Mt. Marsabit Forest and the immediate surrounding lands. The second objective...
