The analysis of polyaromatic hydrocarbons (PAHs) at different depths of soils in the vicinity of auto-mechanic workshops sites in three major towns (Makurdi, Gboko and Otukpo) within Benue State, Nigeria was carried out using GC-MS. The results shows that the total concentration PAHs at sample sites in Makurdi ranges from 532.8 -1122.8 μg/kg, sites in Gboko ranges from 325 - 849.5 μg/kg and sites in Otukpo ranges from 370.9 - 702.2 μg/kg. The order of PAHs contamination in the auto-mechanic workshop sites was Makurdi > Gboko > Otukpo and this signify their patronage of workshop in those town. The overall pattern of soil contamination by PAHs investigated are as follows: Acenaphthylene > Naphthalene > Acenaphthene > Phenanthrene > Anthracene > Pyrene > Fluoranthene > Indeno(1,2,3-c-d)pyrene > Benzo(a)anthrcene > Perylene > Chrysene > Benzo(ghi)perylene > Fluorene > Benzo(k)fluoranthene > Benzo(b)fluoranthene > Dibenzo(a,h)anthracene. This shows that some of the sample sites are contaminated while others are not contaminated.
