Crude oil samples from four oil wells in Nigeria were analyzed for the following seven trace elements: V, Cr, Mn, Fe, Co, Ni and Pb using Atomic Absorption Spectrometric (AAS) analytical technique. The mean concentrations of these elements on a weight to weight basis were found to range from 0.017 ± 0.005 to 1.977 ± 0.397ppm. The results also show that V was the most abundant metal with Ovia 1 Long String (OLS) Oil well containing the highest concentration of V. The V/Ni ratio from the method used shows that Ovia 1 Long String (OLS) and Ovia 1 Short String (OSS) were the most and the least matured oil wells respectively. All the samples had comparably the same V/Ni ratio (1.16—1.77) implying identical source for all the oils. Furthermore, the calculated values of American Petroleum Institute (°API) gravity determined using the measurement of specific gravity (S.G.) of the crude oil samples range from 47.80 to 55.50. This suggests that the samples fall into one category of crude oil classification which in this case is light crude.

Abstract The determination of trace elements in food and soil samples by atomic absorption spectrometry was investigated. A coprecipitation procedure with holmium hydroxide was used for separation- preconcentration of trace elements. Trace amounts of copper(II), manganese(II), cobalt(II), nickel(II), chromium(III), iron(III), cadmium(II), and lead(II) ions were coprecipitated with holmium hydroxide in 2.0 M NaOH medium. The optimum conditions for the coprecipitation process were investigated for several commonly tested experimental parameters, such as amount of coprecipitant, effect of standing time, centrifugation rate and time, and sample volume. The precision, based on replicate analysis, was lower than 10% for the analytes. In order to verify the accuracy of the method, the certified reference materials BCR 141 R calcareous loam soil and CRM 025-050 soil were analyzed. The procedure was successfully applied for separation and preconcentration of the investigated ions in various food and soil samples. An amount of the solid samples was decomposed with 15 mL concentrated hydrochloric acid–concentrated nitric acid (3 + 1). The preconcentration procedure was then applied to the final solutions. The concentration of trace elements in samples was determined by atomic absorption spectrometry.

The content of trace elements in the soils of the Vecherny Oasis (Enderby Land, East Antarctica), where the construction of the Belarusian Antarctic Station started in December 2015, is considered. The results of the research are based on data collected during four Belarusian Antarctic expeditions in the period from 2011 to 2017, and analytical testing of soil samples taken from impacted and non-impacted sites. A total of 22 soil samples were analyzed for the content of trace elements; to compare the levels of accumulation and possible migration pathways, 7 samples of bottom sediments were also analyzed. Determination of trace elements was carried out using the AAS method (Cd, Cr, Cu, Pb, Ni, Zn, Fe, Mn) and emission spectral analysis (about 40 elements). The average values and range of concentrations of trace elements in soils and bottom sediments of the oasis are presented. The possible dependence of the trace elements content on the location positions in the landscape and on the sources of impact is discussed. It is shown, that the variability of metals content in soil profile for background site is low. In comparison with other oases of Antarctica no hotspots have been revealed and no significant areas of soil contamination have been identified yet, which is largely due to the fragmentation of the soil cover and lack of significant sources of pollution.

Proton induced gamma emission (PIGE) method has been developed at the Accelerator Laboratory of Atomic Energy Center, Dhaka (AECD) for the investigation of various human health related specimens. In the present study PIGE analytical technique has been used for the determination of numerous trace elements in some commonly used fish samples which were collected from Islampur area at Savar. During the experimental work the γrays emitted from the prepared fish samples were measured using a Highpurity Germenium (HPGe) detector. The detected 18 elements were Iron, Calcium, Sodium, Magnesium, Aluminum, Potassium, Vanadium, Chromium, Manganese, Copper, Zinc, Selenium, Bromine, Rubidium, Strontium, Cadmium, Iodine, Lead etc. The objective of this study was to measure the concentrations of these trace elements in the collected fish samples and to investigate whether their concentrations are harmful for human health by comparison with limits set by WHO/FAO. The results obtained indicate that Fe, K and Ca concentrations were relatively high in all samples as compared with the other elements. The measured elemental concentration of Fe, Mn, Zn, Cu, Cr and V in all fish samples were found to be above the WHO/FAO recommended limits.
