The subject described in this case report, a movie projectionist, had approximately 25 years of occupational exposure to carbon arc lamp fumes. The carbon arc deposits were visible in histological sections as small granules within macrophages of the tracheobronchial lymph nodes and hepatic Kupffer's cells. Electron microprobe analysis by energy dispersive analysis of x‐rays showed the granules to be composed of the rare earth elements cerium, lanthanum and neodymium, which are the major… 
Lung retention of cerium in humans.
TLDR
This study is believed to be the first one in which lung retention of cerium was estimated in the general population and determination of the absolute concentration of particles containing cerium in BAL fluid and lung tissue samples showed that 1.2% and 1.5% of subjects with previous exposure to mineral particles had high lung retention.
Surface Interactions with Compartmentalized Cellular Phosphates Explain Rare Earth Oxide Nanoparticle Hazard and Provide Opportunities for Safer Design
TLDR
A mechanistic understanding of how REOs induce cellular and pulmonary damage by a compartmentalized intracellular biotransformation process in lysosomes that results in pro-fibrogenic growth factor production and lung fibrosis is obtained.
Urinary Monitoring of Exposure to Yttrium, Scandium, and Europium in Male Wistar Rats
TLDR
Three experiments are described for the suitability and appropriateness of a method to use urine for biological monitoring of exposure to REEs and the high sensitivity of inductively coupled plasma–argon emission spectrometry analytical methods makes urine a comprehensive assessment tool that reflects REE exposure.
Miliary pattern due to occupational lung disease in a patient with laryngeal cancer.
TLDR
A patient with occupational lung disease whose chest CT showed miliary nodular pattern, with concurrent laryngeal cancer who had been engaged in type printing for 22 years is presented.
Urinary Scandium as Predictor of Exposure: Effects of Scandium Chloride Hexahydrate on Renal Function in Rats
TLDR
The results suggest that U-Sc can be a useful tool for monitoring Sc exposure and the formation of Sc colloidal conjugates that deposit in glomeruli may be the cause of a reduction of the glomerular filtration rate.
Toxicological Evaluations of Rare Earths and Their Health Impacts to Workers: A Literature Review
TLDR
It is important to review the toxicological studies to improve the current understanding of the RE compounds in the field of occupational health to establish a sustainable, safe and healthy working environment for RE industries.
Pulmonary toxicity induced by intratracheal instillation of coarse and fine particles of cerium dioxide in male rats.
TLDR
The pulmonary toxicity of Ce-F-instilled rats was found to be markedly enhanced in sharp contrast to that of Ce/C-instilling rats on the basis of equal mass concentration, suggesting clear dependence of the pulmonary toxicity on numbers and sizes of particles.
Twenty-Eight-Day Repeated Inhalation Toxicity Study of Nano-Sized Neodymium Oxide in Male Sprague-Dawley Rats
TLDR
The lowest-observed-adverse-effect concentration of nano-sized Nd2O3 was determined to be 0.5 mg/m3, and the target organ was determinedto be the lung, under the present experimental conditions in male rats.
Cerium oxide nanoparticle-induced pulmonary inflammation and alveolar macrophage functional change in rats
TLDR
CeO2 induced lung inflammation and injury in lungs which may lead to fibrosis, and CeO2 exposure markedly increased suppressor of cytokine signaling-1 at 1-day and elevated arginase- 1 at 28-day post exposure in lung cells, while osteopontin was significantly elevated in lung tissue at both time points.
Sustainability of rare earth elements chain: from production to food – a review

TLDR
It is important to review the current understanding of these elements in the environment, showing the effects of REE exposure in mining, soil, water, plants and food, in order to improve the sustainability management of REe chain.

Rare-earth pneumoconiosis: a new case.
TLDR
The diagnosis derived from the finding, in the bronchoalveolar lavage fluid, of abnormal levels of La, Ce, Nd, Sm, Tb, Yb, and Lu, which were demonstrated also in the nails, suggesting an absorption of the RE from the lung.
Human exposure to heavy metals. Rare earth pneumoconiosis in occupational workers.
TLDR
A male subject exposed for many years to rare earth (RE)-containing fumes and dusts emitted from carbon arc lamps in photoengraving laboratories was investigated, suggesting that the long-term accumulation of RE in the lungs played a role in the pathogenesis of the observed pulmonary fibrosis of the worker.
Ablagerungen Seltener Erden in der menschlichen Lunge und im Tierexperiment
TLDR
Deposits of rare earths could not be detected using routine or special staining technics, but their presence in the tissue was clearly demonstrated by electron microprobe and Debye-Scherrer roentgenographic technics.
Simultaneous determination of trace elements in lavage fluids from human bronchial alveoli by energy-dispersive x-ray fluorescence. 2: Determination of abnormal lavage contents and verification of the results.
TLDR
The limits of the method for characterizing silicosis or asbestosis are discussed, and the low detection limits and the ability to perform multi-elemental analysis permit one to establish or confirm occupational exposure of workers.
