Abstract The study compared ambient air quality between trees and ornamental plants in Calabar Metropolis, Cross River State Nigeria. Data were gathered using primary sources (collection of air quality data: CO, PM2.5, PM10, SO2, and NO2) using Aeroqual series 200 gas samplers. Data obtained were analyzed using tables, simple percentages, and the Independent Samples Test. […]
SPATIAL ANALYSIS OF ENVIRONMENTAL SANITATION PRACTICES IN ILORIN METROPOLIS, NIGERIA
Abstract The study examined the socio-economic characteristics of residents in the different residential zones of Ilorin, identified the existing environmental sanitation facilities, and investigated residents’ sanitation practices. This was with a view to enhancing people’s environmental sanitation practice. Data were collected from primary and secondary sources. A total of 151 questionnaires were administered. Data were […]
COMMUNITY PERCEPTION OF WATERBORNE HEALTH RISKS IN ROCKY-HILL SETTLEMENTS OF NIGERIA: IMPLICATIONS FOR ENVIRONMENTAL JUSTICE AND RURAL HEALTH POLICY IN SUB-SAHARAN AFRICA
Abstract Access to safe drinking water remains a critical concern in many low-resource communities across Sub-Saharan Africa. In Southwestern Nigeria, granite-dominated hill settlements face unique water quality challenges influenced by geological formations and infrastructural limitations. This study assessed community perceptions of water quality and associated health risks in two upland settlements — Ilawe-Ekiti and Aramoko-Ekiti. […]
SOCIO-ENVIRONMENTAL EFFECTS OF COMMERCIAL EXPLOSIVES IN GHANA
Abstract The commercial explosives industry, along with its transport routes, poses a unique multifaceted occupational, public health, and environmental risk in Ghana. The study assessed the health of workers, community impacts and ecosystem susceptibilities to the use of commercial explosives. A pragmatic exploratory-experimental mixed-methods design was used, consisting of 298 respondents randomly sampled from 13 […]
HEAVY METAL CONTAMINATION IN BUSHMEAT: THE IMPLICATIONS FOR WILDLIFE CONSERVATION AND ECOSYSTEM HEALTH
Abstract Bushmeat remains a critical protein source in sub-Saharan Africa but poses risks when contaminated with toxic heavy metals. This study investigated concentrations of mercury (Hg), lead (Pb), arsenic (As), cadmium (Cd), and chromium (Cr) in smoked bushmeat samples from three major markets (Brewery, Ishara, and Ajura) in Ogun State, Nigeria, using atomic absorption spectrometry. […]
GROUNDWATER ARSENIC HEALTH RISK IN CHANDRAPUR DISTRICT, CENTRAL INDIA
Abstract Purposive random sampling at 36 sampling locations was carried out in the post-monsoon season, including 34 (94.44%) from hand pumps and two (5.56%) from dug wells, in order to determine the health risk of groundwater arsenic in Chandrapur district, India. The acid digestion method by using Inductively Coupled Plasma-Optical Emission Spectroscopy was adopted to […]
HYDROMETALLURGICAL EXTRACTION OF ZINC FROM SPHALERITE USING SALTED-OUT ALKALINE (AMMONIA–AMMONIUM SULPHATE): INSIGHTS INTO KINETIC MECHANISMS
Abstract This research explores the hydrometallurgical extraction of zinc from sphalerite (ZnS) using a salted-out alkaline leaching system composed of ammonia and ammonium sulphate, with particular focus on the kinetic mechanisms controlling dissolution. Conventional routes for zinc recovery, including pyrometallurgical and acidic hydrometallurgical processes, remain limited by their high energy requirements, elevated operating temperatures, and […]
INDIGENOUS KNOWLEDGE ON DROUGHT PATTERN AND COPING STRATEGY AMONG THE MAASAI PASTORALISTS IN KAJIADO COUNTY, KENYA
Abstract Maasai pastoralists have used indigenous weather forecasting as tool for decision making, a knowledge passed down through generation. For instance, local knowledge indicators are used to determine onset of rainfall, predict drought and dry spells. It is important to understand the use of traditional weather forecasting among the Maasai pastoralist for effective climate change […]
INTELLECTUAL CAPITAL, OWNERSHIP STRUCTURE AND PERFORMANCE OF LISTED NON-FINANCIAL FIRMS (INDUSTRIAL GOODS COMPANIES) IN NIGERIA
Abstract The study examined impact of intellectual capital and ownership structure on performance of listed non-financial firms (industrial goods companies) in Nigeria. In particular, this work examined the contribution made by relational capital in determining the performance of non-financial firms (industrial goods companies) in Nigeria; tested the moderating effect of human capital on the performance […]
ECO-PHYSIOLOGICAL PERFORMANCE OF Picralima nitida IN FRAGILE ECOSYSTEM
Abstract This study evaluated the eco-physiological responses of Picralima nitida seedlings grown in soils contaminated with different concentrations of spent lubricating oil (SLO). Morphological, physiological, and biochemical parameters were assessed across five treatments (T1-T5) vis 0L/ha, 3736.67L/ha, 7473.33 L/ha, 11210L/ha, 14946.67L/ha of spent lubricating oil in soil (uncontaminated, low, average, high and very high contamination) […]
