Abstract

The evaluation of aliphatic and total petroleum hydrocarbons (TPH) in soil and groundwater sample from Industrial Area of Coal Camp Enugu State, Nigeria was carried out. The analysis was done using Gas Chromatography–Flame Ionization Detection. Human risk assessment was carried out using the Risk Integrated System of Closure model to determine the Hazard quotient (HQ). Analysis of the soil and groundwater samples indicates significant levels of contamination compared to the control. The subsurface soil leaching to groundwater analysis revealed that only about an average of 0.01% TPH in the soil leaches into the groundwater. The HQ for all the soil samples exceeded that of the control at all depths. The soil and also groundwater in industrial area of coal camp is significantly contaminated with aliphatic and total petroleum hydrocarbons. Thus, there is the need for holistic and sustainable monitoring and remediation of aliphatic and total petroleum hydrocarbons in the environment.Keywords: Aliphatic hydrocarbons, Total petroleum hydrocarbons, Human risk assessment, Automobile waste
