Abstract
The current study included measuring the concentrations of total petroleum hydrocarbon compounds and the concentrations of polycyclic aromatic compounds in the water and sediments of four stations of the Shatt al-Arab, It is Al-Maqil, Al-Ashar, Shatt al-Arab and Abu al-Khasib, seasonal from summer 2021 to spring 2021, as well as measuring a set of important environmental factors, which are (water temperature, electrical conductivity, salinity, total dissolved solids (TDS), pH, and dissolved oxygen). In addition to measuring some heavy metals its Arsenic, Vanadium and Cadmium. The water temperature values ranged between(23-12.5°C), Electrical conductivity between (1.404 ̶ 4.58 mS/cm), Salinity between (1.2 ̶ 2.6 ppt), Total dissolved solids (TDS) between (2932-1042mg/l), and pH between ( 7.51̶ 8.58). And dissolved oxygen between (2.11 ̶ 10.40mg/l). The values of the concentrations of heavy elements in the waters of Shatt Al-Arab stations were given, where Arsenic recorded the highest value of 1.99 µg/l in the Abu al-Khasib station during the Autumn season, and the lowest value of 0.11 µg/l in the Al-Ashar station during the summer, while the highest value of vanadium was 9.1 µg/l at Al-Maqil station during the summer, and the lowest value was 4.49 µg/l at Shatt Al-Arab station during the spring. As for cadmium concentrations, it reached its highest value of 0.336 µg/l at Shatt Al-Arab station, and the lowest value of 0.018 µg/l during the winter at Abu station. fertile. The concentrations of the compounds were estimated Total petroleum hydrocarbons in water and sediment, the highest concentration of total petroleum hydrocarbon compounds in the water reached 33.027 µg/l in Al-Maqil station during the winter season, and the lowest value was 2.995 µg/l in Abu Al-Khasib station during the summer season, while the sediment reached its highest value of 55.882 µg/l weight. dry weight at Al-Maqil station during the winter season and the lowest value was 5.692 µg/l dry weight at Abu Al-Khasib station during the summer season, As for polycyclic aromatic compounds in water and sediments, they reached the highest value of 30.255 ng / l during the winter season at Al-Maqil station and the lowest value of 5.085 ng / l in the summer of Abu Al-Khasib. While the highest value in the sediments was 69.966 ng/l dry weight in Al- Maqil station. During the winter, the lowest value was 7.841 ng/l dry weight in Abu Al-Khasib station during the summer.
