【 摘 要 】

The concentration and pattern of carcinogenic polycyclic aromatic hydrocarbons (PAHs) werestudied in top and bottom soil in the vicinity of fuel stations in Abraka Nigeria, using gas chromotograph (GC)Hawleth Packard 6890. Analysis of results show that sample D(0.03979mg.kg-1)>C(0.01592mg.kg-1)>A(0.01155mg.kg-1)>B(0.00325mg.kg-1)>E (0.00191mg.kg-1). Investigation also reveals that all tested samples arecontaminated, with mean values ranging between 0.000207±0.00026mg.kg-1 and 0.002123±0.00303mg.kg-1.Similarly, spearmen’s rank correlation coefficient (SRCC) of sample points At/Ab (0.99), Bt/Bb (0.99), Ct/Cb (0.98),Dt/Db (0.96) and Et/Eb (0.98) show a high and positive correlation between contaminants from top and bottom soil ineach sample point. Molecular ratio analyses also show that petroleum origin is the chief source of PAHscontamination in all samples except in the control that is characterized with pyrogenic and petrogenic source.
