مصادر و توزع الفحوم الهيدروجينية العطرية المتعددة الحلقات (PAHs) في المنطقة المقابلة لكورنيش مدينة طرطوس - سورية

The distribution and sources of 14 compounds of Polycyclic Aromatic Hydrocarbons (PAHs) in marine water and sediment samples were studied. These samples were collected seasonally from 10 different locations of Tartous city (Syria) during the period Apr. – Nov. 2010. The concentrations of PAHs in the water samples of the study areas were affected by location and sources of pollution resulted from the domestic waste-water discharge. The total concentration of PAHs ranged from 6.97 to 147.1 ng/l and the petrogenic PAHs compounds containing 3 rings dominated the most sites. The sediment samples were characterized by the low concentrations of PAHs compared to the respective concentrations in the water samples due to the absence of effective depositional processes. The total concentration of PAHs ranged from 1.76 to 55.28 ng/g dw. The petrogenic PAHs compounds containing 3 rings were dominant in the spring and summer, while the pyrogenic PAHs compounds containing 4 rings were dominant in the autumn.
