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...
ABSTRACT Plastics are important for man use. It cannot be eradicated nor forbidden. Then how should we go about the debris/waste of plastics? How can we stop the single-use method of plastic? Should we ignore and look for another alternative? These above are some of the questions we ask ourselves on daily basis TABLE OF CONTENTS Title page Acknowledgments Abstracts Literature review Results Recommendations References
Lead has been recognized as a serious environmental pollutant known to cause health hazards to people exposed to. Human activities have spread lead widely throughout the environment; hence exposure to lead and lead chemicals occurred from environmental media. Few studies have captured the exposure of people to lead particularly in the indoor environment, thus, this study was designed to assess the practice and knowledge of household residents to lead exposure in indoor environment in Ibadan, ...
The study was carried out to determine the Prevalence of Cryptosporidium species in HIV Positive and Negative Patients Attending Hong General Hospital and Michika General Hospital Adamawa State, Nigeria. A total of 647 stool and blood samples were collected, 346 from Hong and 301 from Michika from both HIV positive and negative patients. The stool samples were examined for Oocysts using modified ZielhNeelson Acid Fast Stain and the blood samples for HIV confirmation test and CD4+cells count. ...
ABSTRACT The research which is entitled the roles of water resources for socio-economic development of rural communities in jere local government area of Borno state, has the sole objective of identifying the sources of water resources of the respondents in the study area, determine the household income arising from water related activities and to identify the constraints associated with water resources in the study area. Purposive sampling method was used where out of twelve wards five ward...
The global mobile industry continues to experience phenomenal growth, with mobile subscribers inching closer to 7 billion at the end of 2014 according to ITU (International Telecommunications Union), and its penetration varying across geographical spread (ITU, 2015). This literally translates to more than 90% of the world‟s population now with a mobile subscription, an increase of 30 percent within 5 years. It is estimated that an additional one billion subscribers will be added by 2020, th...
The composition and distribution of flora species in wetlands are dependent upon several environmental variables and one of such is seasonality regimes. Seasonal gradients exert profound influence on seedling establishment, regeneration and reproduction of plant species. To this end, rural and urban wetlands were studied to assess the influence of seasonality gradients on phytodiversity richness. A ten 5m×5m quadrat was used to sample the vegetation for density of species with spacing at r...
Assessment of macrophyte abundance and water quality of three impacted inlet streams along Ikpa River Basin were investigated. A 5m x 5m quadrat through systematic sampling was used to sample the vegetation for density and frequency of species. Sediment and water samples were collected and analyzed using standard methods. From the results obtained, a total of 23 macrophyte species from 17 families were encountered. Stream 1 (Ntak Inyang 1) had 7 species, stream 2 (Ntak Inyang 2) had 13 specie...
