| Abstract | Sediment cores retrieved from shallow marginal areas at three stations in the New Calabar River Estuary in southern, Nigeria were evaluated for total hydrocarbon content and the level of trace metals between 2011 and 2012. Result of the core profiles of total hydrocarbon content ranged from 0.001 to 130.80 ppm. The observed profiles corresponded with severe environmental perturbations resulting from massive oil spills. The contamination levels of the respective metals varied and the range of mean values are presented in mg/kg along with variations at statistically significant level (P < 0.05) within two years. The constant rate of supply model which was employed to establish the age and date of sediment displayed increase in bulk sediment accumulation over the past 80 years. |
