Abstract

The study examines some of the pollution determinants of the water of Tigris near Al-Muthanna Bridge in Baghdad for the period (2013-2015), comparing it with the Iraqi and international standards, and indicating the validity of its use for different usages. By analyzing the results of the characteristics of the water , it is found that variation during the research period, and a value was  registered among the environmental determinants allowed for the purpose of drinking concerning  the indicators{ (NO₃^-), acid function (PH) except for the month of May (2014) only, which took the base side for the duration of the research}, and its validity to other indicators {total TDS, EC, chlorides(Cl^-), calcium (Ca ^{+ 2}), sodium (Na ⁺), (C.O.D) , (CO), (-Cl), except for the months (July 2013) and (September 2015) only, has registered a value in the specifications of the World Health Organization (WHO) for irrigation purposes, it registered higher percentage when compared to the Iraqi standards, and the ratio of sodium absorption  (SAR) has been registered within the category (S1), it is a type of water with low sodium that can be used in any soil. All the indicators recorded value within the environmental limits allowed for the purpose of building and construction and animal consumption. Its validity fluctuated for industrial uses.
