Abstract

The purpose of the present study was to investigate bacterial and heavy metals pollution in rivers located near Al-Qurna city, Basrah, Iraq. The samples collected from November 2016 to February 2017 from three stations. The heavy metals analysis revealed that the mean concentration of iron, lead and zinc were highest at station 2; 0.35, 0.02 and 1.29 mg/L, respectively. The highest copper concentration was observed in the water sample from sampling station 3 (0.18 mg/L). In this study, 80 samples were collected from three different stations in Al-Qurna city. To find out pathogenic bacteria culturing technique was used followed by staining for identification of bacterial specie. In St. 1 were found 19 samples (23.75%) pathogenic bacteria, 16 samples (20.00%) from St. 2 and 13 samples (16.25%) from St. 3. Four Different bacterial species were reported (Escherichia coli, Pseudomonas aeruginosa, Enterobacter aerogenes and Staphylococcus aureus). E. coli was mostly isolated specie that was identified in 18 samples (22.50%) followed by P. aeruginosa 14 samples (17.50%), S. aureus 12 samples (15.00%) and E. aerogenes 7 samples (8.75%).
