Environmental study of water quality, some heavy metals and Bacterial pollution in Euphrates River water in the city of Nasiriya

This study was aimed to detect possible environmental effects on the Euphrates River in Nasiriyah city. Two sites were selected along the study area it during from November 2016 to April 2017.Physical and chemical properties are measured (air and water temperature , pH , salinity, as well as the average of the some heavy metals Pb, Ni and Cd ,the present study was isolated and diagnosis some of bacteria in the water. The result revealed that a clear balance between the temperature of the water and the air in the stations study. The maximum rate of air temperature was (24˚) in the second station, the lowest rate was (23˚) in the first station .While the water was above the value of (22˚) in the second station ,and the lowest value was (20˚) in the first station. Furthermore the PH was tend to basel . It is reached the highest value (8.10) in the second station ,and the lowest value (7.95) in the first station. Also found there was change in the value of salty for station in the study. the concentrations of heavy metals in water for the second station were higher than in the first station, for, Pb and Ni and Cd concentrations were 1.98, 1.03, 0.24 respectively. The present study was isolated types of bacteria such as Escherichia coli، Pseudomonas sp،Aeromonus sp.
