Concentration of some Polycyclic Aromatic Hydrocarbons in soil samples of Kirkuk province, Iraq
Abstract In order to evaluate the quantity of twelve PAHs (Naphthalene, Tetraphan and Acenaphthylene Fluorene, Phenanthrene, Anthracene, Pyrene, Benzo [a] Anthracene, Ovalene, Chrysene, Benzo [a] fluoranthene and DiBenzo [ah] Anthracene) in the soil samples from Kirkuk province, seven sites (Ras El-Gesr, Benja Ali, Wahed Hozeran, North Oil Company (NOC), Lillan, Kubri and Chimen) were selected using Gas Chromatography (GC) during the autumn 2017 and winter 2018. The results showed that the highest concentration of individual hydrocarbons during the autumn season was for the Acenaphthylene compound in the NOC site 131.19 μg/kg, and for Naphthalene compound, was 100.543μg/kg. The NOC recorded the highest concentration of total hydrocarbons 891.65 μg/kg. For the winter season, the highest concentration of polycyclic aromatic hydrocarbons was recorded for the Fluorene compound at the NOC site 79.19 μg/kg. Fluorene and Naphthalene compounds achieved the highest averages for the season (43.24 and 42.984 μg/kg) respectively, and recorded the location of the NOC, the highest summation of total hydrocarbons amounted to 609.77 μg/kg.
