To assess the oil obtained from the shea nuts for personal, commercial, and industrial use, this study focuses on the extraction process, the optimal solvent for extraction, thermodynamics and kinetic studies, and characterization of the oil. Using different solvents as well as extraction temperatures and times, the oil was extracted using the solvent extraction method.

Groundwater in the coastal areas of Ghana: Quality and associated health risks.

Self-supply water sources, particularly groundwater sources, play key roles in the water supply ecosystem of developing countries. Recent studies indicate that groundwater sources in coastal communities in Ghana are under threat from improper waste management practices, seawater intrusion and atmospheric aerosol deposition. In this study, Water Quality Index (WQI) and Nemerow's Pollution Index (NPI) were employed to assess groundwater quality in four coastal communities of Ghana.

Seasonal variations and health risk assessment of microbial contaminations of groundwater in selected coastal communities of Ghana.

This study investigated seasonal variations in microbial contaminations of groundwater and associated health risks in four coastal communities (Essiama, Winneba, Accra, and Keta) in Ghana. Membrane filtration methods, sanitary risk inspection, and quantitative microbial risk assessment were employed, respectively, to (i) quantify bacteriological quality, (ii) identify risks to contamination, and (iii) assess health risks associated with in groundwater. Results showed 70.

Nonparametric assessment of mangrove ecosystem in the context of coastal resilience in Ghana.

Cloud cover effects make it difficult to evaluate the mangrove ecosystem in tropical locations using solely optical satellite data. Therefore, it is essential to conduct a more precise evaluation using data from several sources and appropriate models in order to manage the mangrove ecosystem as effectively as feasible. In this study, the status of the mangrove ecosystem and its potential contribution to coastal resilience were evaluated using the Google Earth Engine (GEE) and the InVEST model.

Assessing the combined effect of household cooking fuel and urbanicity on acute respiratory symptoms among under-five years in sub-Saharan Africa.

Background: This study sought to investigate the association between urbanicity (rural-urban residency), the use of solid biomass cooking fuels and the risk of Acute Respiratory Infections (ARIs) among children under the age of 5 in sub-Saharan Africa (SSA).

Methods: Cross-sectional data from the most recent surveys of the Demographic and Health Survey Program conducted in 31 sub-Saharan African countries were pooled for the analysis. The outcome variables, cough and rapid short breath were derived from questions that asked mothers if their children under the age of 5 suffered from cough and short rapid breath in the past two weeks preceding the survey.

Assessment of environmental degradation in two coastal communities of Ghana using Driver Pressure State Impact Response (DPSIR) framework.

In this study, a qualitative research method using Driver Pressure State Impact Response (DPSIR) framework was employed to assess the drivers of environmental degradation and their implications on Anlo and Sanwoma coastal communities in the Western Region of Ghana. Pollution Index (PI) and Environmental Risk Factor (ERF) were estimated in Pra and Ankobra estuaries, respectively, in Anlo and Sanwoma communities to complement the qualitative assessment in the studied coastal communities. The state and condition of the coastal ecosystems are critical to the well-being and livelihood of the residents of the two coastal communities.

Impact assessment of high-risk analytes in produced water from oil and gas industry.

This study characterizes and evaluates the constituents of produced water at production wells and dumping sites. The study examined the impact of offshore petroleum mining activities on aquatic systems for regulatory compliance and the selection of management and disposal options. The physicochemical analyses of produced water from the three study locations were within the permissible range for pH, temperature, and conductivity.

The need for alternative pest management methods to mitigate risks among cocoa farmers in the Volta region, Ghana.

The objective of this study is to assess the adoption of alternative pest management methods to reduce risks among cocoa farmers in the Volta region. Cultural control methods found to be the most practiced alternative pest management, especially in the Ho West district where majority of the farmers were more knowledgeable of alternative pest control methods. There was significant relationship between agrochemical shop services (χ = 13,028, p < 0.

Estimating global water, sanitation, and hygiene levels and related risks on human health, using global indicators data from 1990 to 2020.

Water quality improvement, sanitation, and hygiene have been demonstrated to have positive impacts on health, social, and economic development. However, global understanding of water quality, sanitation, and hygiene is limited. The study extracted data from the Joint Monitoring Programme (WHO/UNICEF) and the Demographic and Health Surveys (DHS) to estimate global water, sanitation, and hygiene (WASH) levels.

Earth System's Gatekeeping of "One Health" Approach to Manage Climate-Sensitive Infectious Diseases.

Global response to climate-sensitive infectious diseases has been uncertain and slow. The understanding of the underlying vulnerabilities which forms part of changes created by forces within the Earth system has never before been critical until the coronavirus disease 2019, "COVID-19" pandemic with the initial developmental phase linked to weather elements and climate change. Hence, the heightened interest in climate-sensitive infectious diseases and GeoHealth, evident in the renewed calls for "One Health" approach to disease management.

Groundwater pollution assessment in a coastal aquifer in Cape Coast, Ghana.

This work presents an assessment of the chemico-physical and microbial quality of water samples from hand-dug wells in the shallow aquifer of three communities neighbouring the University of Cape Coast, Ghana. Sanitary risk inspection was undertaken at each well location and the physical parameters including electrical conductivity, pH, Dissolved Oxygen (DO) and etc. were measured in situ via probes.

Quality assessment and potential health risk of heavy metals in leafy and non-leafy vegetables irrigated with groundwater and municipal-waste-dominated stream in the Western Region, Ghana.

Vegetables cultivated in soil irrigated with untreated groundwater and municipal-waste-dominated (MWD) stream can elevate the concentration of heavy metals (Cd, Fe, Zn, Hg, Cr, and Ni) in edible parts of the crop, affecting food safety and public health worldwide. This study assessed the quality, sources, and distribution of heavy metals in surface soils, MWD stream and groundwater, and edible tissues of leafy and non-leafy vegetables from a major urban farm in the Sekondi-Takoradi metropolis, Ghana. Human health risk due to exposure to the metals in frequently consumed vegetables were investigated.

Assessment of surface water quality status of the Aby Lagoon System in the Western Region of Ghana.

The pollution status of the Tendo Lagoon, the upstream section of the Aby Lagoon System, was investigated. The water temperature, pH, turbidity, dissolved oxygen (DO), electrical conductivity (EC), nitrates (NO ), and phosphate (PO ) levels were evaluated using samples taken during the wet and dry seasons to assess the variabilities in water quality in the area. The water quality data was subjected to paired t-test, One-way ANOVA, Factor Analysis, Cluster analysis (CA) as well as a Water Quality Index (WQI) evaluation using the Canadian Council of Ministers of the Environment (CCME) model.
