Studies were carried out on several aspects of rare earth elements (REEs), such as the theory and practice of their applications in agriculture, their geochemical behaviors in natural and agricultural ecosystems, the mechanisms for the increase of crop yield using REE-fertilizer, and their toxicology.
In the current review, we focus on the rare earth elements, thallium, and tellurium. It has been documented that they can pass through the gastrointestinal tract and accumulate in the human body causing short- or long-term structural or functional alterations that can eventually lead to a toxic effect. 1.1 Rare Earth Elements
Abstract. The accumulation of rare earth elements (REEs) in soil has occurred due to the pollution caused by the exploitation of rare earth resources and the wide rare earth fertilizers in agriculture. The accumulation of REEs has a toxic effect on the soil macrofauna community. 12 study samples were collected near a mine tailings …

This work focuses on the determination of rare earth elements (REE) in Brazilian agricultural supplies by instrumental neutron activation analysis (INAA). The results obtained have shown that La, Ce, Nd, Sm, Eu, Tb, Yb, Lu and Sc are present within a large range of mass fractions in the agricultural supplies analysed. The thermophosphate and …
IUPAC has defined rare-earth elements (REEs) as a group of 17 elements having similar physical and chemical properties constituting less than 20% of naturally occurring elements (Gwenzi et al. 2018).The average concentration of REEs in Earth's crust is 150 to 220 mg/kg, which occupies nearly 3 × 10 −4 % of the total Earth's crust. …
Rare earth elements (REEs) are naturally distributed in the environment, and are increasingly being used in agriculture and high technology materials worldwide, thereby increasing anthropogenic contamination and environmental risks. ...

It is known that rare earth elements (REEs) comprise a homogenous group of elements in the periodic system. They include the elements scandium (Sc), yttrium (Y) and 15 lanthanides with successive atomic numbers from 57 to 71. In fact, the term "rare earth elements" is misleading because these elements are not rare.
