Abstract
Four species of Ceratophyllum (Ceratophyllum demersum, Ceratophyllum echinatum, Ceratophyllum muricatum, and Ceratophyllum submersum) were exposed to high concentrations of Pb, Cd, and Ni in a water growing solution to determine their suitability for phytoremediation. All administered heavy metals had very poor translocation ratios to upper plant parts; as a result, metal uptake was restricted to the roots, especially Pb. The amount of metal in the nutrient solution and the genus of the water plants affected the species' capacity to extract and translocate Pb, Cd, and Ni. Comparing the examined species to comparable irrigation trials in the scientific literature, we find that their capacity to accumulate Cd in leaves is among the highest ever recorded. It was established which root development was preferable when encouraged by Cd. This species-specific reaction might be a component of a Cd resistance mechanism. The study showed a low level of dissolved oxygen and high concentrations of vital requirement for oxygen note that the level of DO decreases and BOD and COD increase annually due to the accumulation of pollutants in the river and the increase in population has been removed high levels of pollution with heavy metals using aquatic plants.
