Background and Objectives: In recent years, water pollution has caused damage to the environment, organisms, and humans. Phosphate can be named as one of these pollutants. Phosphate is a major nutrient contributing to eutrophication in water bodies and the resulting harm to organisms and even humans. This research investigated the phytoremediation potential of Nasturtium officinale in removing phosphate from water sources.
Materials and Methods: Experiments were conducted in situ in a stream downstream of Taleghan Dam using synthetic wastewater at two concentrations: 5 and 10 mg/L. Samples were analyzed using a colorimetric method.
Results: The results showed that in autumn and spring, the phosphate concentration decreased after 60 minutes compared to the initial concentration introduced into the chamber. However, in winter, phosphate release back into the water by the plant was observed.
Conclusion: Based on the obtained results and evidence, and considering factors such as environmental conditions, seasonal changes, variable nutrient levels, and luxury consumption, it can be said that Nasturtium officinale (Watercress) is an efficient phosphate remover in water resources. This plant can be used for treating wastewater and phosphate-containing water sources to prevent the adverse effects of this pollutant.
