This study determined the concentrations of Polycyclic Aromatic Hydrocarbon (PAHs) in the soil around a University power generating set. Two soil samples A and B were taken at distances 10m and 15m, respectively from a University Power generating set. PAHs were extracted from the soil samples and analysed using the Gas Chromatography Mass - Spectrophotometry (GC-MS) operated in selective ion monitoring mode (SIM). The result showed that the concentration of PAHs obtained in the Soil Sample A ranged from 0 to 33.24 µg/g, while Soil Sample B ranged from 0 to 40 µg/g. The total concentration of PAHs obtained were 92.15 and 151.18 µg/g, for Soil Samples A and B, respectively. Principal Component Analysis (PCA) showed PAHs in the soil around the power generating are heavily supplemented by different sources around the University environment. The result obtained however showed that the total concentration of PAHs was higher than the permissible European limit of 1000 µg/kg for residential and agricultural soil.
