Abstract/Overview Factors that mostly affected household garbage management were; inadequate garbage disposal facilities in town and residential areas whereby 87% agreed and 13% disagreed (M=3.41, SD, 0.965), lack of enough damp sites whereby 86% agreed while only 14% disagreed (M=3.27, SD, 0.965), unsustainable collection, transportation and disposal systems whereby 83% agreed and 17% disagreed(M=3.07, SD,0.873), and recycling of domestic waste whereby 81% of the respondents agreed and 1...
Abstract/Overview Malaria transmission in arid and semi-arid regions of Kenya such as Baringo County, is seasonal and often influenced by climatic factors. Unravelling the relationship between climate variables and malaria transmission dynamics is therefore instrumental in developing effective malaria control strategies. The main aim of this study was to describe the effects of variability of rainfall, maximum temperature and vegetation indices on seasonal trends of malaria in selected he...
Abstract: Discoveries of huge uranium deposits along the Letlhakane and Serule area in Botswana, led and motivated various researchers to investigate the long term effects of these discov eries. In addition to economic benefits, the possibility of environmental pollution is also high. This study assesses the indoor radon concentration levels in Serule area. Radon ( 222Rn) is of interest because, it is a daughter radionuclide of Radium-226 (226Ra) from the Uranium-238 (238U) decay series and ...
Abstract: Waterborne diseases, especially infectious diarrhoea, remain a public health concern particularly in developing countries where many lack access to safe clean water. The quality of water is assessed using bacterial indicators. However, they may not fully imitate the threat from other non-bacterial pathogens like enteric viruses. The aim of the study was to ascertain and establish the viral load, the seasonal and spatial distribution of rotavirus and norovirus (GI and GII) in sewage...
Abstract: The increasing population growth, depletion of natural recourses from mining and similar activities, and consequent insistent climate change have triggered diverse environmental challenges. It is well known that acid mine drainage (AMD) from mining operations in South Africa constitutes a serious environmental problem which requires heightened and crucial attention. The contamination threats from AMD presents a severe risk requiring prevention and mitigation measures for curbing co...
Abstract: Waste stabilisation pond system has been used more especially in developing countries for sewage treatment. The objective of this study was to investigate the hydraulic and performance efficiency of Palapye waste stabilisation ponds. The hydraulic efficiency was evaluated through drogue, pond geometry and sludge accumulation assessment. The performance efficiency was evaluated through periodic sampling and analysis of physiochemical and bacteriological parameters of individual unit...
Abstract: Shortage of water for agriculture has resulted in the need to explore the use of wastewater for irrigation, however this can pose a health problem to the people emanating from the produced food as a result of the accumulation of pollutants. The purpose of this research was to investigate the accumulation of some heavy metals and bacteriological indicators in the different parts of spinach vegetable irrigated with secondary wastewater effluent treated through a pilot filtration syst...
Abstract The prevalence of diverse factors affecting maintenance management determines the impact of such factors on the maintenance of prison facilities. This study investigates factors that affect the maintenance management of prison facilities in South-West, Nigeria. Questionnaires were used to collect data from the prison staff in the maintenance unit of all prisons situated in South-west, Nigeria. The statistical tools employed for the study were percentage, mean scores, kendall's coeff...
SUMMARY We present a joint analysis of newly acquired gravity and teleseismic data in the North Tanzanian Divergence, where the lithospheric break-up is at its earliest stage. The impact of a mantle upwelling in more mature branches of the East African Rift has been extensively studied at a lithospheric scale. However, few studies have been completed that relate the deep-seated mantle anomaly detected in broad regional seismic tomography with the surface deformation observed in the thick Arc...
ABSTRACT A mathematical model describing the dynamics of Nitrogen transformation and removal in a maturation Waste Stabilization Pond (MWSP) system receiving industrial wastewater was developed. Simulation of the processes was done using STELLA 8_1®, based on the principle of conservation of mass. Besides, measurement of different parameters input to the model was made. Model simulation and mass balance analysis results show that nitrification was responsible for the majority of nitrogen tr...
ABSTRACT A study was undertaken to determine the total hydrocarbon (THC) and heavy metal contents of water (surface: 0-15 cm and bottom: 2-13 m), sediments (intertidal and waterbed) in coastal areas of Cross River and Akwa Ibom States of Nigeria affected by a major oil spill in 1998.
ABSTRACT Urban environmental noise pollution has impact on the quality of life and it is a serious health and social problem. The aim of this study was to assess the sources and noise levels, and possible impacts in selected residential neighbourhoods of Ibadan metropolis. Structured questionnaire was used to elicit information from respondents on demographic and neighbourhood characteristics, sources of noise and perceived effects of noise pollution. Noise level meter was used to determine ...
ABSTRACT The concentration levels of selected heavy metals, (Cu, Cd, Zn, As and Cr) were determined in the soil (µg/g) and water (ppm) samples collected at Ikogosi Warm Spring, Ekiti State, Nigeria. After digestion, Atomic Absorption Spectrophotometer (AAS) was employed for the determination. The study area was at Latitude of 7o 35' 38.9'' , Longitude of 4o 58' 52.6'' and at average elevation of 479m above mean sea level (msl). The average concentrations (µg/g) of the heavy metals in the so...
Abstract The interconnection between weather and climate and the performance, well-being, and human health cannot be overemphasized. The relationship between them is of both local and global significance. Information about weather, climate, and thermal environment is very important to human health and medical practitioners. The most crucial environmental information needed by medical practitioners and for maintaining human health, performance, and well- being are thermal conditions. The study...
Since the late 90s, the Niger Delta of the Federal Republic of Nigeria has been faced with many ecological threats. These include cholera outbreak, Lassa fever, oil spillage, black soot and flooding, among others. However, this essay focuses on black soot, oil spillage and flooding in three communities in Rivers State, one of the six states in the Niger Delta. These communities are most affected among the state's total of over one hundred. Their names are Aluu, Rumuolumeni, and K-Dere communi...
