“…3 Eu(III) applications in multiple industries have increased the risk of human exposure to the metal, especially in settings relevant to mining, processing, and recycling operations. [14][15][16] Hence, a deep understanding of Eu(III) biochemistry is necessary to minimize potential adverse health effects that may result from its use. However, the toxicological profile of Eu(III) has only been partially characterized, with most studies focusing on the identification of median lethal doses in different biological systems, [17][18][19][20] or the accumulation in tissues and organs in vivo after different exposure routes.…”

Europium is a lanthanide metal that is highly valued in optoelectronics. Even though europium is used in many commercial products, its toxicological profile has only been partially characterized, with most studies focusing on identifying lethal doses in different systems or bioaccumulation in vivo. This paper describes a genome-wide toxicogenomic study of europium in Saccharomyces cerevisiae, which shares many biological functions with humans. By using a multidimensional approach and functional and network analyses, we have identified a group of genes and proteins associated with the yeast responses to ameliorate metal toxicity, which include metal discharge paths through vesicle-mediated transport, paths to regulate biologically-relevant cations, and processes to reduce metal-induced stress. Furthermore, the analyses indicated europium promotes yeast toxicity by disrupting the function of chaperones and cochaperones, which have metal-binding sites. Several of the genes and proteins highlighted in our study have human orthologues, suggesting they may participate in europium-induced toxicity in humans. By identifying the endogenous targets of europium as well as the already existing paths that can decrease its toxicity, we can determine specific genes and proteins that may help to develop future therapeutic strategies.

“…As a result, local beach sands and coastal marine sediments are strongly contaminated by Cu, Co, Zn and other heavy metals (Shumilin et al, 2000;2005). However, the impacted zones and the penetration depth into the sedimentary column are ostensibly limited in size (Rodríguez Figueroa, 2010;Rodríguez et al, 1998;Shumilin et al, 2000aShumilin et al, , 2000b.…”

“…mining), and increased public exposure to the lanthanides, both from various commercial products and from production wastes/effluents. Increased mining activity has been shown to result in increased rare earth releases and mobility, whether this mining is of the rare earth materials themselves [15], of other metals [16–19] or even coal [20,21]. In regions with high levels of rare earth elements (REE), elevated levels of REE are found in humans [15,22], and other organisms [23].…”

The increased demand for the lanthanides in commercial products result in increased production of lanthanide containing ores, which increases public exposure to the lanthanides, both from various commercial products and from production wastes/effluents. This work investigates lanthanide (La, Ce, Pr, Nd, Eu, Gd and Lu) binding properties of self-assembled monolayers on mesoporous silica supports (SAMMS™), that were functionalized with diphosphonic acid (DiPhos), acetamide phosphonic acid (AcPhos), propionamide phosphonic acid (Prop-Phos), and 1-hydroxy-2-pyridinone (1,2-HOPO), from natural waters (river, ground and sea waters), acid solutions (to mimic certain industrial process streams), and dialysate. The affinity, capacity, and kinetics of the lanthanide sorption, as well as regenerability of SAMMS materials were investigated. Going from the acid side over to the alkaline side, the AcPhos-and DiPhos-SAMMS maintain their outstanding affinity for lanthanides, which enable the use of the materials in the systems where the pH may fluctuate. In acid solutions, Prop-Phos-and 1,2-HOPO-SAMMS have differing affinity along the lanthanide series, suggesting their use in chromatographic lanthanide separation. Over 95% of 100 µg/L of Gd in dialysate was removed by the Prop-Phos-SAMMS after 1 min and 99% over 10 min. SAMMS can be regenerated with an acid wash (0.5 M HCl) without losing the binding properties. Thus, they have a great potential to be used as in large-scale treatment of lanthanides, lanthanide separation prior to analytical instruments, and in sorbent dialyzers for treatment of acute lanthanide poisoning.
