【 摘 要 】

Soil samples contaminated with spent motor engine oil collected from Abakaliki auto-mechanic site wereanalyzed to determine the concentration of polycyclic aromatic hydrocarbon (PAH) components which are often targets inenvironmental check. Identification and quantification of the PAH components was accomplished using a gaschromatographic system (6890 series and 6890 plus) equipped with a quadrupole Mass Spectrometer (Agilent 5975 MSD)after ultrasonic extraction of the sample and clean up of the extract. The results showed that out of the sixteen USEPAtarget PAHs (EPA-16) assayed, only six were detected in varying concentrations in mg/kg. These include Phenanthrenewith concentration range of 0.0172 ± 0.01 to 0.0193 ± 0.02, fluorene (0.0189 ± 0.01), benzo[a]anthracene (0.0162 ± 0.05),chrysene (0.0209 ± 0.02), benzo[b]fluoranthrene (0.0453 ± 0.02) and benzo[k]fluoranthrene (0.0389 ± 0.1). Theconcentration of total PAH components detected in the samples ranged from 0.0184 ± 0.02 to 0.1385 ± 0.2 mg/kg.Implications of PAHs on health were discussed. ©JASEM
