2009 IESS - Assessment Of Polycyclic Aromatic Pydrocarbon Levels In Soils Of The Tema Heavy Industrial Area

Polycyclic aromatic hydrocarbons (PAHs) are hydrophobic organic pollutants that are ubiquitously distributed in the environment from petrogenic, pyrogenic and biogenic sources as a result of combustion. The aim of this study is to assess the concentrations of PAHs in soils at the Tema heavy industrial area. Surface-soil (0-10 cm) samples from fifteen representative sites at the Tema Oil Refinery and its environs as well as other installations in the Tema heavy industrial area were randomly sampled and analysed for 16 USEPA priority and four (4) other polycyclic aromatic hydrocarbon concentrations. The analytical methods employed in the study involved:
1. Soxhlet extraction of surface soil with dichloromethane.
