Rare earth elements (REE) are critical components of green economic development, but their intensive exploitation and application are causing environmental damage. Research on REE is limited, and phytoextraction technology seems promising for reducing REE pollution and achieving resource circulation.
Rare earth elements (REE), with their distinct physical and chemical properties, are critical components of green economic development. Intensive exploitation and application of REE are wreaking havoc on the environment. But research on REE is still limited to a small number and in a few countries. With the growing interest of REE in modern technologies and their potential ecological risks, phytoextraction seems promising for both REE pollution reduction and resource circulation. This paper summarizes the recent findings in the literature concerning REE hyperaccumulating plants and relevant accumulation mechanisms. Additional interests should be focused on a broader range of plant species and a global scale to achieve a sustainable REE supply.Novelty statement This paper summarized the referenced potential rare earth elements (REE) hyperaccumulator plants that accumulated higher than REE 100 mu g/g and discussed their accumulation and translocation mechanisms. We addressed the synonyms of Dicranopteris pedata, Dicranopteris dichotoma Bernh., and Dicranopteris linearis. Although Dicranopteris pedata has been extensively studied in the sense of REE hyperaccumulation, active phytoextraction outside of its native range, as well as in accumulation of the precious heavy rare earth elements, may be difficult. Thus, further interests should take these disadvantages into account.
