The Araceae family is considered one of the oldest and largest families in the order Arecales, class Monocotyledoneae. This family consists of an estimated 2,600 species. It is grouped into terrestrial or aquatic shrubs, vines, and herbs, but most of them are terrestrial plants (del Pozo et al., 2020). Due to the diversity of this family, it is widely used for different purposes such as food sources, medicine, fiber production, horticulture, agroforestry, and phytoremediation (Moodley et al., 2016). The Araceae family, as hyperaccumulators used in phytoremediation, can tolerate a significant amount of heavy metals present in both soil and water. The uptake of heavy metals happens in the root, which passes through the shoots in the aboveground part of the plant, minimizing the heavy metal present on the surface of the soil and water. Studies also suggest that it is due to the presence of several plant genes, metal ligand synthesis, and the oxidative stress responses of plants. Due to the successful removal of contaminants from the environment through the phytoremediation of plants in the Araceae family, the researchers wanted to discover the effectiveness and ability of the P. hederaceum, which is in the same family, to perform phytoremediation—specifically rhizofiltration.
