| Popis: | This study included the selection of three stations, two of them on the Tigris River passing through the city of Samarra, and the second station representing industrial wastewater - Samarra. The study period was for six months, starting from October 2021 until March 2022. The study included knowing the chemical, physical and biological properties of the industrial wastewater plant and river water and observing the effect of industrial wastewater on the water quality in the Tigris River. The chemical factors included pH, dissolved oxygen and the biological requirement for oxygen, while the physical factors included air temperature, water temperature and total dissolved salts. The results showed that the pH values tended to be alkaline , ranging between 6.6 - 8.7, and dissolved oxygen showed similar values, ranging between 3.8 - 9 mg / l, and the values of the vital oxygen requirement ranged between 0.8 - 30 mg / l, the air temperature ranged between 7 - 32 ° C, the water temperature ranged between 5 - 26 ° C, the values of total dissolved salts ranged between 210 - 1380 mg / l, the total number of coliform bacteria (TC) 0 - 1100 cells / 100 ml. |
