Levels of polycyclic aromatic hydrocarbon in the soil around typical automobile repair workshops in Nigeria.

Background: This study determined the levels of polycyclic aromatic hydrocarbons (PAHs) in the soil around typical automobile repair workshops in Nigeria. Risk assessment associated with human contact with the soil was carried out using hazard quotient (HQ) and incremental life cancer risk (ILCR) from human unconscious ingestion and dermal contact with the soil.

Methods: Soil samples were obtained at different automobile workshops in Ado-Ekiti, Western Nigeria.
