This study investigated the relationship between per capita income and environmental degradation in Africa, using longitudinal data on suspended particulate matter and organic water pollutants. The specific objective was to estimate environmental Kuznets curves for two indicators of environmental quality and to establish whether the estimated relationships conform to the inverted U-shape hypothesis. The results of the empirical investigation generally suggest the existence of an environmental Kuznets curve for suspended particulate matter. In the case of organic water pollutants, the evidence weighs more in favor of rising pollution as per capita income increases. The turning point levels of income established for the two indicators of environmental quality were however generally low, when compared to evidence from existing studies. On the face value, this suggests that African countries may be turning the corner of the environmental Kuznets curve, much faster, and at lower levels of income, much in line with the emerging idea of a "revised environmental Kuznets curve". The results also suggest that economic growth and rising incomes may matter in African countries in order to curb pollution from these pollutants, but more stringent policy measures, particularly at the industrial level would be required to curb environmental degradation from organic water pollutants. © 2011 Elsevier Ltd.

The concentrations of metals (Cd, Pb, Ni, Cr, Cu, Co, Fe, Mn, and Zn) were determined in selected brands of canned mackerel, sardine, and tuna in Nigeria with a view to providing information on the dietary intakes of metals and lifelong health hazards associated with the consumption of these products. The concentrations of metals were determined by using atomic absorption spectrometry after acid digestion. The mean concentrations of metals in canned mackerel, sardine, and tuna were found as 0.04-0.58, 0.06-0.44, 0.32-0.83 μg/g for Cd; 0.05-2.82, 0.70-2.98, 0.23-2.56 μg/g for Pb, 1.33-11.33, <0.20-17.53, nd-34.2 μg/g for Ni, 0.49-3.79, 0.22-1.89, 0.66-14.39 μg/g for Cr, 0.33-0.92, 0.03-1.51, <0.08-1.31 μg/g for Cu, 0.11-2.17, nd-0.75, 0.14-0.50 μg/g for Co, 6.45-26.90, 6.06-53.54, 3.06-95.78 μg/g for Fe, 2.30-3.84, 0.95-21.78, 1.65-2.33 μg/g for Mn, 1.15-7.19, 3.60-17.88, 1.21-5.35 μg/g for Zn, respectively. The mean concentrations of Cd, Pb, and Fe in some of these brands of canned fish were above their permissible limits while other metals occurred at levels below their permissible limits. The estimated daily intakes of metals from consumption of 20.8 g fish per day by a 60 kg body weight adult were below the provisional tolerable daily intakes for Cd, Pb, Ni, Cr, and Cu and recommended daily intakes for Co, Fe, Mn, and Zn. The estimated target hazard quotients of the examined metals were less than 1 in the majority of the samples indicating no long-term health hazard at the present circumstance.

Greenhouse gas emission and its effect on the environment have gained the attention of researchers, environmentalists and policy makers in recent times. This is as a result of its devastating impact both on the climate and the environment. Records of natural gas produced and natural gas flared in Nigeria from 1999 to 2009 were collected and subjected to descriptive analysis as well as the Reference Approach method of greenhouse gas determination. Result showed that the total gas produced in Nigeria from 1999 to 2009 was 502 million cubic meters while 237 million cubic meters, representing 47% was flared. Result also showed that the total gas flared reduced from 23 million cubic meters in 1999 to 14 million cubic meters in 2009. Result indicates that the total quantity of carbon dioxide emitted between 1999 and 2009 was found to be 457 million metric tons which is 23.1 percent when compared with the global value of 1979 million metric tons. Result further indicates that an estimated sum of 11 billion dollars is lost annually to gas flaring in Nigeria. It is recommended that the government should put in place appropriate and implementable policies to end gas flaring in Nigeria. © 2012 Elsevier Ltd.

The concentrations of metals (Cd, Pb, Ni, Cr, Cu, Co, Fe, Mn, Zn and Al) were determined in thirty brands of popular of underarm cosmetics in Nigeria with a view to providing information on the levels of metals and the risk of exposure to metals by humans through long time usage of these products. The concentrations of metals in these samples of underarm cosmetics were measured by using atomic absorption spectrometry after acid digestion. The concentrations of metals in these types of underarm cosmetics studied ranged from <0.15 to 1.2μgg-1Cd, <0.02 to 11.2μgg-1Pb, <0.03 to 4.9μgg-1Ni, <0.1 to 25.0μgg-1, <0.02 to 2.8μgg-1Co, 2.0 to 6.4μgg-1Cu, 4.7 to 91.2μgg-1Fe, <0.05 to 14.1μgg-1Mn, 77.9 to 132μgg-1 and 69.2 to 83,500μgg-1Al. The results of this study indicate that Cd, Pb, Ni, Cr and Co were presents in these types of underarm cosmetics at concentrations below the regulatory control limits for metal impurities in color additives for cosmetics and suggested limits following good manufacturing practice. The estimated margin of safety (MoS) indicated that the concentrations of the examined metals in these underarm cosmetic products present no potential risk to the users. The continuous use of these brands of underarm cosmetics represents a potential source of human exposure to metals such as aluminum in the local area of the breast, particularly to the upper outer quadrant. © 2015 Elsevier Inc.

Human identification is a major task undertaken in forensic sciences. Palato-rugoscopy is based on the principle that no two palates are the same. The study of palatine rugae and the study of fingerprints are sometimes complementary as they operate in similar methods based on same scientific basis. The study intends to describe the shape and gender distribution of the palatine rugae and their prevalence in the studied population. The study sample consisted of 84 subjects, 42 males and 42 females of Urhobo ethnic and cultural background, between 17 and 30 years old, with full complement of maxillary teeth, drawn purposively from Abraka. The prevalence of palatal rugae shapes was: line (27.2%), sinuous (21.1%), angle (18.1%), polymorphhic (15.5%), point (7.5%), curve (6.2%), circle (4.2%). The total number of palatal rugae shape in the overall sample was 520, with females being slightly higher (51.5%) having mean of 6.38 (SD 1.45) than males (48.5%) having mean of 6 (SD 1.72). However, the difference between male and female was not statistically significant. The individualized pattern of palatal rugae makes it a reliable guiding tool in forensic identification.

Sequential chemical extractions were performed in order to determine the forms of metal contaminants such as cadmium (Cd), cobalt (Co), copper (Cu), chromium (Cr), iron (Fe), manganese (Mn), lead (Pb), nickel (Ni), and zinc (Zn) in the soils around the asphalt plants in Delta State, Nigeria. The results indicated that the reducible phase (consisting of Fe(III) and Mn(IV) oxides, and hydroxides) is the major host of Cd at the surface horizon, while at the sub-surface horizons, cadmium existed mainly in the residual form. Cobalt was predominant in the residual and Fe-Mn oxides fractions. Copper existed mainly in the residual, Fe-Mn oxides and organic bound fractions. Iron and manganese were predominantly in the residual, Fe-Mn oxides and exchangeable fractions. Higher amounts of Mn were extracted in the hydroxylamine hydrochloride extraction than Fe because of specific reduction of Mn oxide by hydroxylamine and specificity of dissolution with respect to ferric oxides. Fe-Mn oxides and residual fractions formed the major host of Pb in these soil profiles while the residual fraction formed the major host of nickel with significant amounts in the exchangeable fraction. Zinc was found predominantly in the Fe-Mn oxides fraction at the topsoils and the residual fractions at the sub-surface soils with significant amounts of zinc occurring in the organic matter bound fraction. The average mobility index of metals in the topsoils follow the order Ni > Cd > Co > Mn ≈ Zn > Fe > Cu > Pb > Cr. The results of the present study revealed that Fe-Mn oxides formed the major scavenging mechanism for metals in these soils. On average the amounts of these metals in the readily available form never exceeded 23% at all depths and sites, implying that these metals are not readily available at the prevailing soil physicochemical conditions. However, significant amounts of these metals existed in the Fe-Mn oxides fraction and may be available if the pH and redox conditions of the soil change, which could be induced by flooding. The results obtained provided information on the speciation, bioavailibity, and mobility of metals in soils in the vicinity of asphalt plants, which are useful in environmental quality management and environmental forensics. © 2013 Taylor and Francis Group, LLC.

A geophysical investigation was carried out in Oleh, Nigeria to determine the groundwater potential and the geological structure of the area. The method employed in this study was the Vertical Electrical Sounding (VES) using the Schlumberger configuration. The data obtained were interpreted by computer iteration process and results when compared with lithologic log from existing borehole indicate a four layered formation. The first aquifer identified in this study is located along the second layer with resistivity ranging from 347.4 to 1137 Ωm and depth ranging between 2.0 and 3.7 m. Analysis of this layer shows that this aquifer is unconfined and prone to pollution since it underlay's a loose and clayey sand formation that is very thin. The second aquifer is a viable potable water formation with resistivity range of 416.7 to 1459.2 Ωm and a thickness range of 12.0 to 14.9 m. The depth of the aquifer ranges from 21.8 to 29.7 m. Boreholes for potable groundwater are therefore recommended within the forth layer because of its quality and viability. © 2011 Academic Journals.

The quality of life (QL) of retired academics reengaged in some Nigerian Universities was studied using physical health, subjective happiness, life satisfaction and psychological well-being domains and a measure based on control, autonomy, self-realization and pleasure (CASP) as indicators. Satisfactory QL was indicated all respondents (>50% maximum points), but physical health was poor (<30%). Compared to the preretirement period, respondents indicated satisfactory present condition. Significant differences (t test) due to gender, age, living with/without spouse, mandatory/voluntary retirement, and rank occurred in some QL indicators. Except for physical health, the QL indicators were positively associated (r =.31-0.69, p <.05-0.01). Satisfactory location was indicated and was positively related to subjective happiness (r =.52-.76). Thus, the QL of reengaged retired academics did not deteriorate because of continued activity. © 2012 Copyright Taylor and Francis Group, LLC.
