In the present research, the distribution and subcellular localization of cadmium in the roots, shoots, and leaves of Monochoria hastata were evaluated to understand structural and ultrastructural changes caused by the metal. Several visual toxic symptoms such as withering, chlorosis, and falling of leaves appeared in M. hastata , especially at 15 mg L −1 Cd concentration. Analysis of Cd concentration by ICP-OES showed that Cd concentrations in the root were significantly higher than those in the shoot and found to be in the following order: root > stem > leaf. Bioconcentration factor (BCF) and translocation factor (TF) were used to evaluate accumulation and transfer of metals from the root to aerial parts. TF of Cd in M. hastata was
