  Trace elements in the kerogen fraction of hydrocarbon source rock samples from two wells obtained from the Cretaceous units of the Orange Basin, South Africa were determined using X-ray fluorescence spectrometry, in order to determine their distribution and geochemical significances. The concentrations of the elements (As, Ce, Co, Cu, Fe, Mo, Ni, Pb and V) determined ranged from 0.64 to 47,300 ppm for the samples analysed. The total organic carbon (TOC) values indicate that the samples are organic rich but did not show any trend with the distribution of the trace metals except Ce, Mo and Pb. Dendrogram cluster analysis discriminated the samples into three groups on the basis of their level of thermal maturity. Thermal maturity has a significant effect on the distribution of the trace metals. Cobalt/Ni and V/Ni ratios and cross plots of the absolute values of V and Ni indicate that the samples had significant marine organic matter input. The V and Ni contents and V/(V + Ni) ratio indicate that the organic matter of the source rocks had been deposited in reducing conditions. Despite the similarities in the organic matter source input and depositional environment of the organic matter of the samples from the two well, cross plots of Co/Ni versus V/Ni and Mo/Ni versus Co/Ni were able to reveal subtle differences. Cluster analysis of the samples was also able to reveal the subtle thermal maturity differences of the samples.

  The physico-chemical and trace metal analyses of battery factory wastewater were carried out in this study. Samplings were done three times in a period of nine months at settling tank (i.e., before treatment) and at final discharge point (after treatment). High levels of pH, conductivity, Pb, Fe and Zn were observed, which may affect the health of the aquatic ecosystem of the receiving river. The high levels of conductivity, Pb, Fe and Zn may also adversely affect the health of the community that uses the receiving river directly for domestic use without treatment. The treatment technique employed by the factory is grossly ineffective for the removal of Pb, Fe and Zn but effective for removal of Cu and Cd.

  A preliminary study of the rare earth element contents of some Niger Delta oils was carried out to evaluate their influence on petroleum system of the Niger Delta Basin. The oil samples were obtained from an onshore field in the Niger Delta and analyzed using Inductively Coupled Plasma Mass Spectrometric (ICP-MS) analytical technique. Four Light Rare Earth Elements (LREE), La, Ce, Nd and Pr were detected. Their concentrations varied from 0.009 to 0.49 ppb, 0.058 to 1.58 ppb, 0.01 to 0.47 ppb and 0 to 0.18 pbb, respectively. All the LREE showed significant and positive correlation with each other and also have significant correlation with aromaticity index (Toluene/nC7). The study showed that REE are not good for classification of oils but provide another tool in oil-oil correlation.
