“…The LDH activity was examined in 1.0 mL of reaction mixture with 100 µL of pyruvic acid (2.5 mg/mL phosphate buffer) and 100 µL of reduced nicotinamide adenine dinucleotide (NADH; 2.5 mg/mL phosphate buffer), and the rest of the volume was adjusted with phosphate buffer (0.1 mol/L, pH 7.4). The rate of NADH oxidation was determined by following the decrease in absorbance at 340 nm for 3 a spectrophotometer (Varian-Cary 300 Bio). The amount of LDH released is expressed as LDH activity (IU/L) in culture media.…”

Introduction: Nanoparticles are extensively applied in pharmaceutical, agriculture, food processing industries, and in many other fields. In the current experiment, we have determined the mechanism of toxicity of lanthanum oxide nanoparticles (La 2 O 3 NPs) on human liver cell lines. Methods: Before the investigation, we have characterized the size and shape of La 2 O 3 NPs using dynamic light scattering (DLS) and transmission electron microscope (TEM). The mean size of the La 2 O 3 NPs was found 32 ±1.6 nm with a sheet-like shape. The cytotoxicity effect of La 2 O 3 NPs for 24 h on CHANG and HuH-7 cells was determined by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and lactate dehydrogenase (LDH) assays. Results: The cytotoxicity was observed in a concentration-dependent manner in both cells but NPs were more toxic to HuH-7 than CHANG cells. Generation of reactive oxygen species (ROS) was determined using fluorescent dye 2′,7′-dichlorofluorescin diacetate (DCFDA) and high green fluorescence was observed in HuH-7 cells than CHANG cells. Oxidative stress biomarker such as glutathione (GSH) was decreased and antioxidant enzyme superoxide dismutase (SOD) was increased but SOD level was decreased in HuH-7 cells than CHANG cells. Apoptotic cells were determined by using fluorescence-activated cell sorting (FACS) analysis. Maximum percentage of the apoptotic cell was observed at 300 µg/mL in HuH-7 cells. DNA doublestranded breakage was observed by comet assay and maximum DNA damage was found in CHANG cells than HuH-7 cells at 300 µg/mL La2O3 NPs for 24 h. Conclusion: Thus, this study demonstrated that La2O3 NPs were toxic to human liver cells and induced more toxicity in HuH-7 cells than CHANG cells.

“…The demand in rare earth elements (REE) has been increasingly greater year in year out, as their application in military, pharmaceutical and nuclear industry, metallurgy, electronics, medicine, chemical engineering 1 , agriculture 2 and others has been on the upscale. The reason of their widespread use in important fields are their different chemical, electrical, magnetic, metallurgical, optical and catalyst properties.…”

The rare earth elements represent an increasingly more important industrial resource. The increased use may result in waste generation, and their impact upon the environment quality has not been studied sufficiently. Their interaction with soil has been studied in this paper. Freundlich adsorption isotherm has been determined for lanthanum, erbium and gadolinium at three different soil types (humus, clay and sand type), whereas sequential extraction at these soil types has been applied for lanthanum and neodymium. The interaction of certain rare earth elements with soil components has been tested as well as the quantity in which these elements are bound to soil and later on extracted in solutions. The objective was to determine the soil capacity for disposal, first of all, of the electronic waste that contains these elements and to assume their fate in the environment.

“…Foliar spraying, seed treatment, fertilizer, and culture medium with REEs were carried out on a variety of crops, and the productivity of crops including wheat (Triticum aestivum) (Liang et al, 2005), soybean (Glycine max) (Cynthia et al, 2015), and other crops (Tommasi et al, 2020) increased by 5-15% (Xiong et al, 2000). It was found that REEs had a "hormesis effect" on plant growth and development (d'Aquino et al, 2009;Wen et al, 2011;Ochi et al, 2014).…”

Rare earth elements (REEs) of low concentration are usually beneficial to plant growth, while they are toxic at high concentrations. The effects of treatment with lanthanum (La) (10 and 20 μM), cerium (Ce) (10 and 20 μM), and terbium (Tb) (10 and 20 μM) on seedling growth of alfalfa (Medicago sativa L.), which is one of the most important perennial leguminous forages in the world, were studied. The results showed that all three REE treatments quickened the germination of seeds. The length of shoot under La (20 μM) treatment was significantly shortened (P < 0.05). In addition, treatment with La, Ce, and Tb had a “hormesis effect” on root length. There was a significant decrease in chlorophyll content on treatment with the three REEs, and the degree of decline was in the order of La < Ce < Tb, under the same concentration. In vitro experiments and quantum chemical calculations were further performed to explain why the treatments with REEs reduced the chlorophyll content. In vitro experiments showed that La, Ce, and Tb treatments reduced the absorbance of chlorophyll, and the decrease followed in the order of La > Ce > Tb. Quantum chemical calculations predicted that the decrease in absorption intensity was caused by the reactions between La, Ce, Tb, and chlorophyll, which formed lanthanides-chlorophyll; and there were five types of stable lanthanides-chlorophyll. In conclusion, the decrease in chlorophyll content on treatment with REEs was caused by the change in chlorophyll structure.
