“…With annual increasing amounts exploited and diversity of uses explored, rare earth elements (REEs) are extensively applied to industrial, medical, zootechnical, and agricultural fields [1,2]. The REEs are not as rare in geological abundance as other toxic metals, and China has around 90% of the world's detected REEs [3,4]. The expanding applications of REEs have led to a great deal of human exposures from occupational, environmental, medical, and iatrogenic routes [5].…”

The current study aims to investigate the influence of five rare earth elements (REEs) (i.e., lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), and gadolinium (Gd)) on the growth of Sprague–Dawley (SD) rats, and to explore the accumulation characteristics of REEs in tissues and organs with different doses as well as the detoxification and elimination of high-dose REEs. Fifty healthy male SD rats (140~160 g) were randomly divided into five groups and four of them were given gavage of sodium citrate solution with REEs in different doses, one of which was the control group. Hair, blood, and bone samples along with specific viscera tissue samples from the spleen and the liver were collected for detection of REEs by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Treated rats expressed higher concentrations of REEs in the bones, the liver, and spleen samples than the control group (P < 0.05). Few differences were found in relative abundance of La, Ce, Pr, Nd, and Gd in the hair and the liver samples, although different administration doses were given. The relative abundance of Ce in bone samples was significantly lower in the low-dose group and control group, whereas the relative abundance of La and Pr in the bone samples were highest among all groups. Although in the REEs solution, which was given to rats in high-dose group, the La element had a higher relative abundance than Ce element, it ended up with higher Ce element relative abundance than La element in the spleen samples. REEs had a hormetic effect on body weight gain of SD rats. The accumulation of the measured REEs were reversible to low concentrations in the blood and hair, but non-reversible in the bones, the spleen, and the liver. Different tissues and organs can selectively absorb and accumulate REEs. Further inter-disciplinary studies about REEs are urgently needed to identify their toxic effects on both ecosystems and organisms.

“…Essential metals occur naturally, while the nonessential metals, having no positive effect, are considered hazardous even in low quantity [30]. However, excessive use of essential metals has been linked to cellular and systemic disorders [31]. Further, in the long term, the accumulation of these metals in soil can lead to the deterioration of agricultural land, eutrophication, and the absorption of toxic substances [32].…”

The sediment pollution caused by different metals has attracted a great deal of attention because of the toxicity, persistence, and bio-accumulation. This study focuses on heavy metals in the hyporheic sediment of the Weihe River, China. Contamination levels of metals were examined by using “geo-accumulation index, enrichment factor, and contamination factor” while ecological risk of metals were determined by “potential ecological risk and risk index”. The pollutant accumulation of metals ranked as follows: “manganese (Mn) > chromium (Cr) > zinc (Zn) > copper (Cu) > nickel (Ni) > arsenic (As) > lead (Pb)”. The geo-accumulation index identified arsenic as class 1 (uncontaminated to moderate contamination), whereas Cu, Cr, Ni, Zn, Pb, and Mn were classified as class 0 (uncontaminated). According to the enrichment factor, arsenic originated through anthropogenic activities and Cr, Ni, Cu, Zn, and Pb were mainly controlled by natural sources. The contamination factor elucidated that sediments were moderately polluted by (As, Cr, Cu, Zn, Mn, and Pb), whereas Ni slightly contaminated the sediments of the Weihe River. All metals posed a low ecological risk in the study area. The risk index revealed that contribution of arsenic (53.43 %) was higher than half of the total risk.

“…The increase application of Nd in high-tech processes and products leads to the release of this element into the environment, mainly in the rivers and coastal areas not only due to the disposal of e-waste (50 million tons in 2018) but also from the mining activities which is the primary source of REEs discharge into water systems (Adeel et al, 2019;UNEP et al, 2019). The concentration of Nd in waters depends on several factors such as climate, geology and vegetation and its most common oxidation state is Nd(III).…”

“…The concentration of Nd in waters depends on several factors such as climate, geology and vegetation and its most common oxidation state is Nd(III). A wide range of REEs concentrations has been detected in agricultural soils (< 15.9-249.1µg/g) and in groundwater (< 3.1-146.2 µg/L) at various sites worldwide (Adeel et al, 2019), with Nd being the third element most abundant (after Ce and La).…”
