Abstract: The results of grain size analyses revealed that most of the samples in the studied areas lie between muddy sand to gravelly sand texture which reflect moderately, well sorted grain size. The sediments of the four areas lie in saltation population rather than traction and suspension population this support the results that the sediments are mixed from different environments such as fluvial, beach and shallow marine. Studying the characteristic feature for all chromatographic pattern of four samples reflect typical to weathered crude oil. The concentrations of Cu, Zn, Pb, Fe, Mn and V in the studied area are being within the permission levels while Ni and Cd concentration show high level of concentration. The contaminations level were found due to petrogenic origin and their sources are either weathered or highly weathered crude oils and or used lubricating oil. Their detection gives an indication of recent and continuous petroleum inputs.
