Contamination Status: Geo-Investigation of Stream Sediments of Ilubirin Bitumen Rich Area of Ondo State, Southwest Nigeria Using Oxide and Trace Metals

Description

The stream sediments of Ilubirin bitumen rich area was investigated for contamination using enrichment factor (EF), contamination factor (CF), geo-acummulation index (I-geo), and pollution load index (PLI).Statistical analysis was used to determine the anthropogenic or natural sources of the contamination if any.The result of EF shows that majority of the elements in the stream sediment are minimally enriched in the sediments as their values are less than 2 ( EF < 2). Co is moderately enriched since it has values that are greater than 3 in locations 3 and 7. Major oxides were determined by the use of Inductively Coupled Plasma-Mass Spectrometry ( ICP-MS), while the trace elements were analysed withthe use of X-Ray Fluorescence (XRF) analytical technique in the laboratory of the Stellenbosch University ,South Africa. CF results showthat Cs and Cr have moderate contamination on the sediments because they both have values higher than 1 but less than 3 (1 1) an indication of low contamination. I -geo values indicate that Cs, Ni, Cr, and Mo have uncontaminated to moderate contamination having values in the class range of0-1. Other elements have no contamination impact on the environment because they have values below zero. Zr and Co in locations 3 and 7 have the highest concentration levels which suggest a threat of concern in the stream sediments of the study area. Statistical analysis indicates that the trace metals have mutually, strong and positively correlated relationships indicative of a single natural source contamination suggestive of bitumen. It is suggested that regular geochemical work should be carried out in this area so as to monitor any rise in contamination level and the residents should be advised to avoid making use of the nearby stream water.
