ABSTRACT Cropping systems productivity in the Volta Delta is dependent on complex interconnecting biophysical and socioeconomic determinants. The study analysed the determinants of cropping systems yield and developed an integrated model for managing desired sustainable crop production scenarios. The analysis was conducted on change in yield over time, rainfall, temperature, Land use/land cover (LULC) and soil characteristics. District level crop yield was regressed on the biophysical vari...
ABSTRACT Cases of food contamination and poisoning in boarding schools have been reported in Nigeria. Although researches have been carried out on food safety in Nigerian schools, not many studies were conducted in boarding schools despite the health implications of consuming unsafe food. This study was designed to assess the food safety and hygiene conditions in selected Public Secondary Schools with Boarding Facilities(PSSBF) in Ibadan, Nigeria. Stratified random sampling technique was use...
ABSTRACT Land use/cover alteration within lake basins is occurring at accelerated rate most importantly in developing countries like Ghana. Anthropogenic activities (livelihood change, population growth, agricultural intensification and practices) and natural factors like seasonal variations are in most situations the major cause. To examine the effects of land use/cover on the physico-chemical and biological properties of Lake Bosomtwi, satellite images of the Lake’s watershed covering the...
ABSTRACT Virtually all countries, especially the developing nations, are being confronted with the twin problems of waste management and energy deficit. This development has led to the search for renewable energy sources. Although pig dung, water hyacinth and maize cob have been identified as good feedstocks for biogas production, studies utilising their mixtures have not been fully explored. This study was therefore designed to evaluate the biogas yield and microbial species from mixtures o...
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 Background: Mental illness is a very common mental disorder affecting women, especially in the low and middle-income countries (LMICs). Pregnancy is an increased vulnerability to depression. Most researchers have concentrated on postnatal depression with very little on antenatal depression. This is a major public health concern and needs further investigation. Objective: The main aim of the current research is to assess depression status and its predictors among pregnant women seekin...
ABSTRACT Background: Young adults transitioning from late adolescence to early adulthood (18-24 yrs) experience a growth spurt that imposes an increased need for both macronutrients and micronutrients. Adequate vitamin D levels mainly from sun exposure and diet improves bone function, especially attaining maximum bone strength and density in young adults. Also, the extra-skeletal functions of vitamin D which includes muscle strengthening and improved cognitive performance are all essential fo...
ABSTRACT Microbial contamination of indoor air of operating theatres is one of the risk factors for the development of Surgical Site Infections (SSI). Operating theatre environment, including personnel, can become contaminated with microorganisms capable of causing SSI, morbidity, prolong hospitalization of patients or even death. Studies on indoor air quality particularly the air-borne microbes that are associated with SSI have not been adequately investigated. This study was therefore desi...
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 This study assessed dry season farming profitability and examines farming practices and their influence on the environment. Dry season farming practices identified from the literature were irrigation practices, land preparation, tillage practices and use of agrochemicals. A cross sectional design was adopted as quantitative data was collected from respondents. Five (5) communities along the White Volta River in the Bawku West District were purposively selected based on their proximit...
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 Solid wastemanagement is an established environmental health challenge in most societies. The heterogeneousnature of municipal solid wastemakes its management particularly complex. Waste segregation which is key to proper solid waste management has not been adopted in the Nigerian society. Improper waste segregation could result in diarrheal diseases. The study was designed to assess solid waste segregation as a strategy for improved waste management in Okaka Community, Bayelsa Stat...
ABSTRACT In developing countries, hospital wastewater management is an issue of major concern. The purpose of the study was to evaluate the performance of the waste stabilization pond at the Cape Coast Teaching Hospital in Ghana. Wastewater samples were taken from the raw sewage (anaerobic pond) after screening. The process was repeated in both the facultative and maturation ponds, sequentially. Fifty four samples representing 18 samples each from the three stages of the waste stabilization t...
ABSTRACT In Nigeria, use of urine for fertigation has been limited because of its liquid form, odour and the unsanitary disposal methods. This poses great hazard to man and the environment. Converting urine into dry fertilizer product (struvite) helps extract nutrients contained in urine and also eliminates handling problems. The study was aimed at converting urine to struvite and comparing its effectiveness on plant growth with inorganic fertilizer (NPK). The study involved the extraction ...
ABSTRACT Water-borne diseases, caused largely by lack of potable water, are among the leading causes of morbidity and mortality. Several indigenous water treatment methods have been developed to enhance the quality of drinking water. In Illah, a combination of dried fruits of Xylopia aethiopica and Tetrapleura tetraptera are used for household treatment of water without information on its potency in water purification. There is no documented information on the effectiveness of this treatment...
