Auto mechanic activity in the recent time has significantly contributed to environmental degradation partly due to poor waste management practices and weak enforcement in ensuring operators are located in designated sites. This study therefore investigated the distribution pattern of Poly Aromatic Hydrocarbon (PAH) contaminants around Nekede auto-mechanic village, Owerri. Soil samples (0-30cm) were collected at three separate points. Sediment samples were also collected from two points along the Otamiri River representing sediments (RS) 1 and 2 and a control sample where no mechanic activity existed. Physicochemical parameters were determined using standard methods and Gas Chromatographic system equipped with a single detector (Flame Ionization Detector) — GC-FID for PAHs. The results obtained showed that out of the sixteen US-EPA target PAHs (EPA-16) analysed, only eight were detected in varying concentrations. Total PAH concentrations in the samples were in the order of dibenz {ah} anthracene (29.111mg/kg) > indeno {1, 2, 3-cd} pyrene (20.178mg/kg) > anthracene (10.717mg/kg) > naphthalene (8.340mg/kg) > 1, 2-benzoanthracene (4.124mg/kg) > acenaphthene (2.784mg/kg) > benzo {ghi} perylene (2.324mg/kg) > fluorene (1.421mg/kg). The concentration of total PAH components detected in the samples ranged from 2.564mg/kg to 21.841mg/kg in the study site compared to that of the control site where no PAH component was detected. The results therefore call for public concerns as PAH levels exceeded the maximum permissible limits set by some regulatory bodies. Public health education and regulation on management of wastes in the auto-mechanic workshops are recommended for environmental sustainability.
