Purpose Rare-earth elements (REEs) have been listed as emerging pollutants, and REEs often occur together with heavy metals (HMs) in the environment. Large amounts of REEs and their coexisting HMs enter into the surrounding soils through dust, surface runoff, and leachate, causing serious REE and HM co-contamination and …

Extensive rare earth element (REE) mining activities have caused REE contamination of ambient agricultural soils, posing threats to associated food webs. Here, a simulated lettuce–snail food chain was conducted to evaluate the trophic transfer characteristics and the consequent effects of REEs on consumers. After 50-day exposure to soil, lettuce …

Rare earth elements (REE) is a general term for yttrium, scandium and the lanthanides in group IIIB of the periodic table of elements. Lanthanum (La) is a light REE, and its abundance in the crust is 32 ppm, accounting for 14.1% of all REEs (Dou 2005).Due to its unique and important magnetic and spectroscopic properties and optical features, …

Rare earth elements are widely distributed in the Earth's crust in average concentrations ranging from 150 to 220 mg/kg (Kamenopoulos et al., 2016). ... concerns and contradicting results concerning their biological effects require an extensive understanding of REE ecotoxicology.
