Evaluation of petroleum hydrocarbons in water, fish and plant samples in Degele and Environs in Delta state, Nigeria

摘要

This work measures the total petroleum hydrocarbon in water, fish and plant samples from and around Degele community. Water, fish and plant samples were separately extracted and the extracts examined using gas chromatography with flame ionization detector (GC/FID) after silica gel fractionation. The result of the analysis for water revealed that the mean levels of aliphatic Petroleum Hydrocarbons (PH) in well ranged between 0.004+ 0.002 and 0.004 +- 0.0069 mg/L, pond was between 0.006 +- 0.002 and 0.014 + 0.019 mg/L and the mean river level was 0.008 +- 0.008 mg/L. That of fish ranged between 0.188 + 0.122 and 1.315 + 0.808mg/kg for pond, 0.034 + 0.00lmg/kg for the river and plant ranged between 0.044 and 0.079 mg/kg. Mean aromatic PHs in well ranged between 0.002+ 0.002 and 0.004 +- 0.003 mg/L, pond was between (0.001 +- 0.001 and 0.006 + 0.007mg/L and the mean river level was 0.004 +- 0.003 mg/L. That of fish ranged between 0.003 + 0.002 and 0.038 + 0.025mg/kg for pond, 0.019 + O.OOlmg/kg for theriver and plant ranged between 0.001 and 0.003 mg/kg. The hydrocarbon type was shown to be mainly moderately high molecular weight aromatic and high molecular weight aliphatics.
