The current study was conducted to find out the effect of some different concentrations of heavy metals on the physiological state of aquatic plants by studying their accumulation in their tissues and measuring the concentration of total chlorophyll, carotene and their protein content by exposing the two aquatic plants Potamogeton crispus L. and  Potamogeton pectinatus L. to three different concentrations of (Pb, Fe, Ni) be (10, 20, 30) ppm for 5 weeks.

The results of the study showed an increase in the concentrations of heavy metals in a different way at the end of the experiment in the aquatic plants used in the study compared to the control sample. The response of aquatic plants was studied through chlorophyll, carotene and protein content. At the end of the experiment, a decrease in chlorophyll concentration and protein content was found in the studied aquatic plants compared to with sample control.
