Abstract
This study was conducted on the river Tigris between Albo-Sayf and Hammam Al-Aleel, on four positions stretching along the river for eight months started from November 2010 to June 2011. The study concluded measurement of some biological factors. The results showed that the dissolved oxygen value ranged between (2.63- 813) mg/L, the minimum value was recorded at station of Albo-Sayf at downstream Mosul city at November while maximum value recorded on station 4 Hamam Al-Aleel at April. The range value of biological oxygen demand (BOD5) ranged between (1.93- 17.2) mg/L the minimum value recorded at station 2 Jamasa village at June while the maximum value recorded at station 1 Albo-Sayf at April. While the research showed that the value of nitrate ranged between (0.40- 1.59) mg/L the minimum value was at station 3 Lazaga village at June While the maximum value at station 1 Albo-Sayf at April. The value of orthophosphate ranged (0.21- 1.25)mg/L the minimum value at station 2 Jamasa village while the maximum value at station 1 Albo-Sayf at April. Although the value of Sulfate range (74- 114) mg/L the minimum value at station 1 Albo- Sayf at April , while the maximum value at station 4 Hammam Al-Aleel where there are many water sulfur springs at this station.
