The College of Veterinary Medicine at the University of Baghdad witnessed the discussion of the master’s thesis (Evaluation of bacterial load and heavy elements in the general estuary and their effects on fish) by researcher Muhannad Karim Jaafar Al-Sudani.
The study aimed to determine the levels of heavy metals in water and fish samples of the general estuary river and bacterial contamination and to assess the physical quality of water samples in three cities (Baghdad, Dhi Qar, and Basra).
The letter included collecting three bottled samples (100 ml) of water every two weeks from each location in the city. The sample collected in a cooler box was transferred to the laboratory, and three water samples and three fish samples were collected every two weeks from each location in the city.
The study proved that the concentration of heavy elements (cad and lead) in the mouth of public rivers increased with the progress of flow in cities after Baghdad, and the city of Basra recorded its highest concentration.
The researcher recommended that because of the low level of pollution at the beginning of the general estuary, it is recommended to raise fish there, it is not recommended to raise fish in the general estuary of the Basra River because of its high pollution with heavy metals and bacteria, conducting tests for the presence of pathogenic bacteria in the public estuary and also in the Tigris and Euphrates rivers, and carrying out pesticide detection work in this river and the Tigris and Euphrates rivers as well.
