| Abstract | ||
| The present work comprised the study of presence , origin , type , and distribution of polycyclic aromatic hydrocarbons ( PAH ) in sediments of Shatt Al – Arab river . A total of up to 70 samples of sediment were collected from seven stations along Shatt Al – Arab river for the period of November 2003 to April 2004 . The samples were extracted and concentrations of PAH were determined by high resolution capillary gas chromatography . The concentrations of PAH in sediments of Shatt Al – Arab river varied from 11.83 ng / g dry weight at station 3 to 77.86 ng / g dry weight at station 6 . The dominant PAH compounds were anthracene , fluoranthene , pyrene , perylene throughout the stations . There was a significant relationship between the concentration of PAH and total organic carbon ( TOC ) . The grain size analysis of these sediments indicated that distribution of PAH is related to the texture of the bottom deposit . | ||
