Urea is a widespread organic pollutant, which can be a nitrogen source, playing different roles in the growth of submerged macrophytes depending on concentrations, while high cadmium (Cd) concentrations are often toxic to macrophytes. In order to evaluate the combined effect of urea and Cd on a submerged macrophyte, Cabomba caroliniana, the morphological and physiological responses of C. caroliniana...
Increasing urea import into freshwaters is known to have a negative impact on aquatic ecosystems, however, few data exist about the effects of urea on the physiology and ecology of aquatic plants. In the present study, two submersed aquatic plants, Cabomba caroliniana A. Gray and Elodea nuttallii (Planch.) H. St. John were cultured with urea-enriched solution for 16days and the effects of urea on...
