Abstract

Polycyclic aromatic hydrocarbons (PAHs) are organic pollutants which can end up in the soil due to anthropogenic activities in vehicle repair shops. There is an indirect rise in environmental contamination as population and technology grow which results in a persistent and rapid deterioration of the environment's quality with capacity to support life. Among other environmental components, soils are often where PAHs are deposited. The concentrations of PAHs accumulated in a three auto-mechanic workshops were examined in this study. For the purpose of this study, soil samples were taken seven days in a row from three busy auto-mechanic workshops: Opeyemi Automobile Workshop (O.P.W.S), Ayoola Automobile Workshop (A.Y.W.S) and Ajobiewe Automobile Workshop (A.J.W.S). The examinations of PAHs were performed utilizing conventional analytical techniques. ). For A.J.W.S naphthalene, 2-methylnaphthalene, acenaphthylene, acenaphthalene, fluorene, anthracene, benzo(a)anthracene, chrysene and benzo(b)fluoranthene had 0.18, 0.17, 0.03, 0.05,0.16, 0.14, 0.12, 0.14 and 0.19 mg/kg respectively The concentrations of phenanthrene, anthracene, pyrene, benzo(a)anthracene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene and indeno (1,2,3-cd) pyrene were confirmed to be higher than 1.00 mg/kg in O.P.W.S which confirmed that O.P.W.S is seriously polluted.
