The Effect of the Succession of Seasons on Some Parameters of the Tigris River in Mosul City, Iraq
Nineveh Governorate is the largest city in northern Iraq, which is completely and mainly dependent on the Tigris River, as it is its lifeline. The current study included an assessment of the state of pollution resulting from chemical pollutants released into the Tigris River in the city of Mosul. Samples were collected from five sites, the first was the Rashidiya area and the last was the Al-Busif area during September, November, January and March. Samples taken from the aforementioned sites were used to measure acidity, temperature, oils and grease in addition to sulfates, nitrates, total hardness, calcium and magnesium hardness, turbidity, dissolved solids, and electrical conductivity. The acidity values ranged between 6.2 and 6.99l the temperatures fluctuated between 13.1 & 21.5ºC; the conductivity was -223-621µs/ cm, and the dissolved solids were 227-673PPm, while the turbidity ranged between 10.6 and 954NTU. The values of BOD and COD ranged between (1-31) and (10-93) mg/L, respectively, while the values of oils and fats ranged between (0.2-9) mg/L, and sulfates ranged between (0.076-111.5) mg/L. For nitrates, values were recorded with ranges between 0.104 & 36.9mg/ L. The total hardness and the hardness of calcium and magnesium were between (304-940), (120-520), and (22.4-166) mg/L, respectively. The research aimed to evaluate the water properties of the Tigris River in the city of Mosul during seasonal changes and compare it with the parameters set by official Iraqi and international environmental authorities.Through the present study, it can be concluded that most of the tests indicated that the water of the Tigris River are within the Iraqi and international limits allowed for drinking water and daily uses, except for the vital requirement of oxygen and hardness of all kinds.
