| Abstract | ||
| Summary Several ecological (physical & chemical) factors , are studied as water temperature , pH , total dissolved solids , salinity , nutrients nitrate nitrite and sulfate . Also some heavy elements Zn , Fe , Pb have been measured in the Euphrates river and masab-Alaam river and Garraf river , which is one of the main parts of Tigris river , this was studied basically in monthly period from June 2010 till September 2010 . Monthly changes have been recorded in the investigated factors , and less water temperature had been recorded in Euphrates river was 28ْ ْin September while the highest water temperature was 35ْ in June in Euphrates river . In masab-Alaam river pH was alternate between 7.9 and 8.5 and water temperature in September was less than water temperature in June in Euphrates river .In Al-Garraf river the concentration of the TDS was 410 mg/l in June while the highest concentration was 5630 mg/l in July in masab-Alaam river , and the less salinity was recorded in Garraf river was 0.678 mg/l in August and September compare with other rivers , In contrast with masab-Alaam river which salinity was 9.129 mg/l was recorded in June . The less concentrations of nitrate have been recorded in June in Euphrates river was 0.017 mg/l while highest concentration for nitrite 1.32 mg/l in Garaaf river in June less concentration of sulfide was recorded and it was 22 mg/l ,while the highest concentration was recorded in masab-Alaam river and it was 329 mg/l . The less concentration of Zn in Garraf river was 0.05 mg/l and the highest concentration was recorded in Masab Alaam river and it was 1.88 mg/l , for the months August and September . The less concentration for Pb it was 0.001 mg/l in Garraf river for the months August to September while highest concentration was recorded in July and it was 0.34 mg/l in masab-Alaam river and the smallest percent for Florid which was record in masab-Alaam river was 0.148 mg/l in July and the highest concentration which was recorded in Euphrates river was 0.237 mg/l in June | ||
