Abstract :
The objective of this study is to determine oil pollutants (PAHs) and investigate PAHsource in the sediments of Anzali Lagoon (in Mahrozeh & Selke stations) that can beof high importance from monitoring. Therefore, sampling is made in two wet and dryseasons at Mahrozeh & Selke stations. Finally, making use of GC, the relatedanalyses were performed to determine PAHs. The results showed that mean PAHs insediments of Mahrozeh were 34.839 in dry season and 61.439 ng/g dw in wet season,and in Selke were 80.432 in dry season and 45.439 ng/g dw in wet season. Theamounts of PAHs in Mahrozeh & Selke stations were lower than PAHs in sedimentsof the Persian Gulf countries, (except of UAE and Oman sediments).and also PAHsin Mahrozeh & Selke stations were lower than sediments of Caspian Sea. The sourceof PAHs in Mahrozeh & Selke sediments were both pyrogenic andpetrogenic.Statistical examinations didn’t show significant differences betweenPAHs in sampling seasons.
