The pollution status of Sakumo II and Muni Lagoons and Mamahuma and Gbagbla Ankonufeeder streams, which feed Sakumo II along the coast of Ghana, were assessed and compared.As expected of saline waters, pH values of both lagoons fell within a slightly neutral to salinerange whilst, the feeder streams were moderately saline. Conductivity distribution also showedsaline (.5.0mScm21) characteristics of the lagoons, while, the feeder streams are brackish(1.5–5.0mScm21). DO concentrations in both ...
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous organic pollutants in urban environmentsincluding urban soils. Elevated concentrations of PAHs in urban soils are caused by incomplete combustion of petroleum and coal. This study assesses 16 individual PAH compounds in a total of 112 surficial soil samples. The objective was to assess and compare the levels of contamination as well as examine the main sources of PAHs in four urban agricultural soils using molecular ratios of some specifi...
The most relevant controls on groundwater quality within the Lower Pra Basin in Ghana were assessedusing Q-mode hierarchical cluster analysis (HCA). The objective was to determine the chemical characteristics of the various water groups and subgroups responsible for the groundwater evolution and identify the groundwater recharge and discharge zones within the basin. The Q-mode HCA have characterized hydrochemical data from a total of sixty-eight (68) boreholes and two (2) streams within the b...
Hydrochemical and stable isotopes (18O and 2H) analyses of groundwater samples were employed toestablish the origin of major dissolved ions in groundwater within the Lower Pra Basin. Results showed that, the major processes responsible for chemical evolution of groundwater include: silicate (SiO4)4- dissolutions, ion exchange reactions, sea aerosol spray and pyrite (FeS2) and arsenopyrite (FeAsS) oxidations. The groundwater is strongly acidic to neutral, with pH generally range from 3.5 to 7....
Calcite (CaCO3), dolomite [CaMg(CO3)2], silicatedissolution, ion-exchange and reverse ion-exchangereactions are the predominant processes influencinggroundwater quality in the Savelugu–Nanton District. Themain objective of this study is to characterize groundwaterand delineate water–rock interactions responsible for thechemical evolution of groundwater in the District. Eighty-one (81) boreholes were sampled for quality assessment.Results showed that, the pH of the boreholes are slightly a...
Abstract Several researches have shown that the accumulation of heavy metals in green-leafy vegetables is of increasing concern due to food safety threat and potential health risks. Therefore, the aim of this research was to analyze the amount of heavy metals accumulated in three green-leafy vegetables consumed in Dutse metropolis, Jigawa state, Nigeria. Three (3) samples of each of the vegetables were collected randomly from two (2) different markets in Dutse Metropolis. The sample coll...
This paper demonstrates that interdisciplinary alliances on environmental education projects can effectively address the gap between complex environmental problems in the real world and disciplinary curricula in a university. We describe an alliance between an advanced communication course and a general science course wherein we addressed interconnections of energy efficiency, economics, and global climate change with respect to their impact on individuals, local businesses, and society. This...
This paper explores an application of Catholic theology to mitigate the current destruction of God's creation underway due to global climate destabilization. Specifically it describes the possibility of the U.S. Catholic Church adopting a systematic plan to catalyze the world energy market to shift to solar photovoltaic energy, a non-polluting renewable energy source. The science behind the ecological crisis and climate change in the context of the Catholic basis for environmental stewardship...
As the economic costs of energy and the negative externalities associated with the combustion of fossil fuels threaten the economic viability of greenhouses in northern climates there is a renewed interest in the use of waste heat. This paper presents a technical and economic methodology to determine the viability of establishing waste heat greenhouses using the waste heat from industrial processes in northern climates. A case study is presented of an exchange between a tomato greenhouse and ...
Solar photovoltaic (PV) technology represents a promising method to prevent dangerous global climate change, however full solar penetration demands substantial surface areas, possibly encroaching on arable land. To avoid repeating the mistakes of previous attempts to convert agricultural land to energy, arable land currently used for crops with known health hazards can be considered for conversion. Tobacco is the leading cause of avoidable death globally, and despite increasingly stringent co...

Biostimulation of bacteria degradation of crude oil polluted soil using plantain peels were studied in University of Abuja permanent site. Top soil was collected randomly from different points, sieved and weighed out 3kg into each plastic bucket, and were polluted with 300ml, 250ml and 200ml on each. The plastic buckets were labeled in single form with cotton wool plugged at the base to retain the water. (A,B,C,D,E,F,G,H,I,J) with the control as J without crude oil. After 30 days, the sun-dri...
Cobalt is one of the natural elements that happens to be found throughout the natural environment. This natural element is present in trace amounts in sols, plants, water and our diet. When cobalt is in its pure form it is a steel-grey to black shinny hard metal. Cobalt can also exit as cobalt II and cobalt III which forms a number of both organic and inorganic salts. Cobalt in small proportion is essential to good health. Cobalt is only found in the environment in chemically bonded form...
ABSTRACTBackgroundHand washing is the process of decontaminating the hands, a cheap and effective method of limiting the spread of nosocomial infections. Good hand hygiene involves cleansing hands in between patients or between examining an infected site and a clean body site on the same patient. Proper hand washing practice involves following the WHO accepted guidelines for hand washing. Hand washing is an effective and inexpensive way to prevent diarrhea and acute respiratory infections. Th...
In the study, health risk assessment on heavy metals ingestion was presented through the groundwater drinking pathway for residents in an oil and gas producing area of Rivers State, Nigeria. The level of the ground water pollutionwas examined, the quality of the borehole and the well water was assessedand the quality of the ground water pathway for the resident in the oil and gas producing area was determined and compared with the national and international standards for the drinking water. T...
