| Abstract | ||
| The current study involved measuring the physical and chemical characteristics of the water of the Tigris River in Tikrit and its suburbs at five different sites for a period of six months. The results indicated significant variations across the study sites: turbidity ranged from 8,437 to 16,301NTU; conductivity from 191,833 to 202.38μS/ cm; TDS from 382.77 to 412,944mg/ L, and pH from 6.040 to 6.493. Dissolved oxygen levels ranged between 9.300 and 11.53mg/ L, while biological oxygen demand varied from 2,922 to 4,016mg/ L, and total alkalinity ranged from 56,888 to 62,444mg/ L. Total hardness of the water at the sites ranged from 80,167 to 91,056mg/ L, calcium hardness from 59,222 to 64,778mg/ L, and magnesium hardness from 17,611 to 30,722mg/ L. Furthermore, phosphate concentrations ranged from 3,339 to 3,449µg of phosphate atom/ L, and silica concentrations from 3.40 to 4.58µg/ L.While nitrite values ranged from 0.467 to 0.477µg of nitrogen atom/ L. The results for monthly changes showed that the turbidity values were 4,278 to 24,644NUT, and the pH values were 5,469 to 7,250, while the dissolved oxygen values were 8.86 to 11.24mg/ L, and the biological oxygen demand value was 3,500 to 3,826mg/ L. Moreover, the results showed that the total hardness values ranged from 71,733 to 113,200mg/ L, and phosphate values ranged from 2,998 to 4,808µg of phosphate atom/ L, while nitrite values ranged from 0.454 to 0.532µg of nitrogen atom/ L. | ||
