دراسة لبعض الخصائص الفيزيائية و الكيمائية و البيولوجية لمياه نهر دجلة قرب جسر الشهداء و تقييمها للأغراض المختلفة للمدة (2012-2014)‎

الملخص EN

The research investigates some physical, chemical and biological properties of the Tigris water River near the Alshuhadah Bridge and evaluated these properties for drinking, irrigation industrial and construction purposes for the period (2012-2014), and until July for the year (2014) due to the lack of data for the rest of the year.

Through the analysis of properties results it had been found that there is some variation during the months of the year, as well as between the annual averages for the three years where the Cadmium element did not record any value, which was equal to zero, as well as the iron element except for the month of May for the year (2013).

In addition, it was noted that the Tigris River water near the Alshuhadah bridge in the month of May for the year (2012 ) and the month of July of the year (2013) within the class (C2) which is a brackish water and it needs to filtering operations for some crops which are sensitive to salinity and that due to lack of the total dissolved salts in the water in the mentioned two months(July and May), while it found in the rest of the three years months within the class ( C3) which is a high-salinity water and cannot be used without continuouslydrainage.

The value of (PH) of the water was found within the permissible limits for drinking, irrigation and industrial purposes and has taken the baseband side during the three years with except for the month of December for the year (2012) and the month of April for the year ( 2014) which was neutral in pH (PH = 7), while it noticed that in the month of May for the year (2014) was acidic (PH =6.89) and the value of (TDS), sodium and nitrate for the three years within the permissible limits for drinking purposes.

In addition, the value of the absorbed vital oxygen was within the permissible limits for irrigation purposes.

Also the value of chlorides, carbonates and boron for the three years was within the permissible limits for drinking and irrigation, while the rest items values fluctuated between the permitted and non-permitted to be used for these purposes, Besides that, the values of calcium, magnesium, sodium and chlorides for the three years was within the allowed boundaries for the purposes of building and construction.

While the usage of water for industrial purposes for affected components in industry, it had fluctuated between permitted and non-permitted for using.
