Polycyclic Aromatic Hydrocarbons (PAHs) in water of Al-Kahlaa River in Missan Province, Iraq
Abstract: The present study
was performed to have knowledge of Polycyclic Aromatic Hydrocarbonspollution status in water. The
samples were collected during two seasons (winter and summer 2012 ,2013) from
four different stations) Al-Magideh, Treatment unit, Al-Husaichi and Al-Zubair)
distributed along Al-KahlaaRiver in Missan province, in addition to reference
station lies on the Tigris river before
25 Km from entering to Amara
city. The concentrations of PAHs were determined in by using capillary Gas
Chromatography. Results of the present
study revealed that the total concentrations of PAHs in dissolved fraction ranged from 0.739 ng.l-1 in Reference station
to 1.974 ng.l-1 in Treatment unit during winter, and from 0.300 ng.l-1 in
Reference station to 1.125 ng.l-1 in Treatment unit during summer, while in the
particulate fraction they varied from 0.79 ng.g-1 dry weight in Reference
station to 24.42 ng.g-1 dry weight in
Treatment unit during winter, and from 4.369 ng.g-1 dry weight in Reference
station to 10.545 ng.g-1 dry weight in Al-Husaich during summer. It had been
noticed that there were a predominance of high molecular weight PAHs on low
molecular weight, while BaA/(BaA+Chr)
ratio in water ranged from 0.218 to 0.804. InP/(InP+BghiP) ratio ranged between
0 and 0.578,whereas Fl/Pyratio ranged between 0.150 and 2 ,this give an
indication of the origin of PAHs compounds in water which were mainly
pyrogenic and few from them petrogenic.
