This study was conducted to find out the effect of adding sewage and industrial water on the concentration of Lead and Cadmium elements in aquatic plants during different seasons of the year in Diwaniyah governorate / Iraq. Aquatic plant samples (Arundo and Ceratophyllum) were collected in three replications for all sites and during four seasons: summer (July) 2019, autumn (October) 2019, winter (January) 2020, spring (April) 2020, by three Sites where the first site is located at the entrance to the city of Diwaniyah (the Sania district), which represents the control treatment as it is located before the various pollution ports that pour into the river (such as sewage, hospital waste, factory waste, sewage … etc) and the second site in the city center (Rifaat quarter). The third site is in the Sudair district, which represents the last site of the city of Diwaniyah after the end of all the estuaries and sources of pollution. The results of the study found that the concentration of the two elements (Lead and Cadmium) in aquatic plants (Arundo and Ceratophyllum) increased with the increase of the river’s slope and the increase of the added pollutants. In the summer, the concentration of Lead in the Arundo plant was 6.79 μg.Kg −1 , while its concentration in the Ceratophyllum plant was 7.80 μg.kg −1 in the third site and least in the winter season, for both plants, where the Lead concentration in the Arundo plant was 1.21 μg.Kg −1 and its concentration in Ceratophyllum plant is 1.52μg.Kg −1 in the first site. As for the highest concentration of Cadmium, it was in the summer also, it was 4.04 μg.Kg −1 in the Arundo plant, while it was 4.39 μg in the Ceratophyllum plant. in the third site and the lowest in the winter season, and for both plants, the Cadmium concentration in the Arundo plant reached 1.26 μg.Kg −1 As for its concentration in the Ceratophyllum plant, it was 1.43 μg.Kg −1 in the first site. The Ceratophyllum plant exceeded its absorption of Lead and Cadmium in all the studied sites and seasons.
