Abstract
The current work was done to study some of the chemical and physical properties of the less Zab tributary river and their effect on the ecology Tigris river pollution. The study has been conducted at six stations selected along the river stretching for (49) km for the period from the beginning of October 2013 to May 2014. The water samples have been taken from these stations monthly to determine some selected physical properties such as the electrical connectivity and turbidity, and some selected chemical properties (pH, DO, BOD5, Total Alkalinity, Total Hardness, Calcium Hardness, Magnesium Hardness, Chloride content). The results of the study have shown that the electrical connectivity values are between (270-1693) μs/cm, and the impurity of the water between (0.0 -61.0) NTU. The values of pH in all stations were between (6.6-8.5) .The values of the dissolved oxygen were high and the water has good ventilation in all stations, while the values of BOD5 were unstable. The recorded results of total Alkalinity values were between (108-320) mg/l while the total hardness were between (120-520) mg/ l , Calcium hardness (70-270) mg/l , Magnesium Hardness (16-140) mg/l and chloride (5.99-89) mg/l.
