A quarterly qualitative study of the plankton diatoms within the waters of the Tigris River was conducted, starting from September 2022 until May 2023, to find out the effect of the liquid medical city waste released to the Tigris River on the quality of plankton diatoms within Tigris River for three sites confined between Al-Sarafiya Bridge in the north and Medical City Bridge, the site of Al-Khader Elias in the south, and the middle site affected by sewage waste for the Medical City Hospital Compound, with the study of some physical and chemical variables of the river water. The study was able to record 94 species of diatoms belong to the 26 genera in which pennate diatoms prevailed 74 species belonging to 21 genera while the centric diatoms recorded a smaller number of 20 species belonging to 5 genera. The study also showed the effect of sewage water for hospitals Medical City on the quality of diatoms, which it was few throughout the study period and the waste loaded with organic matter and antibiotics with high concentrations caused a decrease in the number of diatoms species throughout the study period within the site directly affected by waste.
