| Abstract | ||
| For the period Jan.(2006)toFeb(2007) during(14)months,sediment samples were collected from different sites of Iraq southern marsh land;Al-Bargah,Al-Hammar and Al-Gebayesh station.Analysis were done for the determination of total hydrocarbon concentrations using the spectroflurometric method by comparing samples with astandard solution of Iraq crude oil.Total Petroleum Hydrocarbon Concentrations(TPH) indicated that there were regional and seasonal variations.(TPH) ranged from (0.458) µg/g dry weight in Autmn season at Al-Hammr station to (1.250)µg/g dry weight at Al-Gebayesh station during winter(2006).Gaschromatography also used to identify the concentration and origin of n-alkanes in sediment samples,total n-alkanes ranged between(6.53) µg/g dry weight at Al-Hammar station during summer season to (31.46) µg/g dry weight at Al-Gebayesh station during winter (2006).Studying Pristan ,Phytan and Carbon Prefrence Index (CPI) indicated the biogenic source of hydrocarbone compounds. | ||
