| Abstract | ||
| A monthly study has been performed during October 2002 to March 2003 for Tigris river flowing at four stations, the first is Al-Rashdia which is the river enter Baghdad city, the second near oil vegetables factory in AL-Masbah, the third near tanning and leather factory in Saeda and the last station in AL-Twetha about 200 kilometers from the site of Tigris river contact with Dyalla river south of Baghdad. Some environmental parameters such as pH, temperature, turbidity, electrical conductivity, chloride, total hardness, biological oxygen demand, total suspended solids and total dissolved solids have been investigated. It has been found that temperature fill in the range (11.7-30)ºC for four stations and the values of pH fill in the range (6.6-8.3). AL- Twetha contained the highest concentration of BOD (7.5 mg/L), turbidity (100 NTU) at March. The highest values of E.C. (2069 mmhose/cm) at October and chloride (800 mg/L) at November recorded in Saeda . The highest values of total hardness recorded in AL-Masbah (225 mg/L) at November. The values of TSS and TDS (480,2210 mg/L) have been obtained at AL-Masbah and Saeda during March and January respectively. | ||
