This study's goal was to determine the amount of total chlorophyll and its protein content by subjecting aquatic plants Lemina minor to different levels of cadmium [10, 20, and 30 mg/L] for a month. This was done in order to assess how these salt concentrations affected the plants' physiological states. As the study came to a close, the components' quantities in the water plants used for the analysis increased differently than in the control sample, according to the investigation's findings. We looked at the protein and chlorophyll concentrations of water plants that were subjected to heavy metals.
