Abstract

The current study was conducted on the Euphrates River, starting from the Ramadi Center to the city of Fallujah, in four selected sites distributed along the river during the period from (April 2021 - March 2022). Samples were collected from surface water to study the various physical and chemical properties. The study also included measuring the concentration and distribution of some polycyclic aromatic hydrocarbons (PAHs) and predicting their sources in water samples, sediments, and aquatic plants such as Ceratophyllum demersum, Elodea canadensis and Potamogeton crispus. The results showed that the air and water temperature ranged between ((Cº 50-1) and (Cº 32-6), respectively, while the values of water flow (0.3 m/S 0.65 m/S) during winter and spring, the values of pH and conductivity were Electricity and salinity fluctuated between (8.7-7.7), (1349 µs/cm -640 µs/cm) and (0.86 ppt -0.41 ppt The levels of dissolved oxygen ranged between (10.3 mg/l - 7.2 mg/l). The biological oxygen BOD5 ranged from (5 mg/l - 0.7) and the results showed that the river water was alkaline in nature and very hard. Levels of (220 mg/L -65), (38mg/l - 6 mg/l) were reported for total alkalinity and suspended solids, respectively. The results indicated values between (-0.003 and (-3.93) mg/l 0.31 and (3.93). mg/l - 1.2 m/l), total total phosphorous, total nitrogen respectively. In water samples, the lowest value was recorded (0.001 ng/g.dw) Flu. Ant, while the highest value (5.14 ng/g.dw) is Acpy. The lowest concentration in sediment samples (0.001 ng/g.dw). It was reported for Nap while the highest concentration was for (8.22 ng/g.dw) Phen.
