| The Persian Gulf is one of the most important water bodies in the world that has been heavily
developed for crude oil production and exportation. Considering the fact that hydrocarbons may cause
adverse impacts on the aquatic and marginal life, the monitoring of hydrocarbons in marine sediments has
long been considered.
In the present study, the concentrations and sources of aliphatic hydrocarbon (n-alkanes) and polycyclic
aromatic hydrocarbons (PAHs) were determined in seven surface sediments collected from mangrove
forest of Khamir Port. After soxhlet extraction with dichloromethane, samples were analyzed with GCMS.
Twenty-three compounds of PAHs and several n-alkanes (n-C14-n-C33) were analyzed. Total
concentrations of n-alkanes and PAHs were 1644±354 μg/g (dry weight) and 1394±503 ng/g (dry weight),
respectively. The mangrove sediments had higher percentages of lower molecular weight hydrocarbons.
The diagnostic ratios were used for source identification of hydrocarbons. Results showed that the main
source of hydrocarbons is petroleum and petroleum products. |
