Summary: | Vegetation samples from the bitumen deposit area of Southwestern Nigeria were analysed for element contents to assess their level of accumulation from a bitumen deposit area and to provide a framework for the establishment of relationships between the chemistry of the mineral deposit and the vegetation. The element concentrations of the samples were determined using the EDXRF spectrometry technique. Thirteen elements - K, Ca, Cr, Ti, V, Mn, Ni, Cu, Zn, Ga, Rb, Sr and Fe were detected. The results of the calculated concentration ratio (CR) showed that the vegetation samples have high uptake ability (CR > 0.9) from the soil for most of the elements determined. Strong and significant positive correlations exist between some elements, indicating a common source, chemical similarity and/or common natural background levels in the samples. Positive correlations were shown by the results of the cross-plot analysis of the vegetation/soil and vegetation/bitumen, suggesting inter-element correlations between components of the ecosystem and that ecosystem vegetation accumulated the elements via the soil as a result of contamination with the bitumen and also establishing relationships between the aforementioned components of the ecosystem and the bitumen deposit in the area. |
