Abstract

Sediment samples were collected from four selected sites along the Euphrates river near Al-Nassyira city south of Iraq during summer2012 to winter 2013, sixteen PAHs listed by USEPA as priority pollutants were detected.The total of PAHs was ranged from 0.197 ng/g dry weight in summer at station 1 to 80.006 ng/g dry weight in winter at station 3. The LMW/HMW, Flouranthene/Pyrene and Phenanthrene /Anthracene ratio indicated that the source of PAHs was pyrogenic Whereas BaA/(BaA+Chry) ratio indicated that the source of PAHs was pyrogenic and at least petrognic. The highest value TOC % were 1.91% at station 3 in winter while the lowest value were 0.73% at station 1 in summer. The study shows that there is a significant correlations between TOC%, grain size in the sediment with concentration of PAH. The present study indicated that hydrocarbons exist in the study area, but its levels were in acceptable range.
