Subclinical interstitial lung damage in workers exposed to indium compounds
OBJECTIVES The present study was designed to determine whether there is a relationship between indium compound exposure and interstitial lung damage in workers employed at indium tin oxide manufacturing and reclaiming factories in Korea. METHODS In 2012, we conducted a study for the prevention of indium induced lung damage in Korea and identified 78 workers who had serum indium or Krebs von d...
متن کاملIndium Exposure Concentration and Serum Indium Level
The aim of this study was to assess the relationship between indium exposure concentration in the respirable dust fraction (In-E) and indium in serum (In-S) in workers. Methods: A total of 39 workers were studied. The study subjects were categorized into 3 groups, namely, smelting workers (n=7), ITO workers (n=6) in an ITO grinding plant, and other workers (n=26). In-E and In-S ranged from 0.00...
متن کاملHigh levels of indium exposure relate to progressive emphysematous changes: a 9-year longitudinal surveillance of indium workers.
BACKGROUND During the last decade it has been clarified that the inhalation of indium compounds can evoke alveolar proteinosis, cholesterol granuloma, pulmonary fibrosis and emphysema. In this study, we aimed to elucidate the characteristics and time course of pulmonary disorders among indium workers using comprehensive pulmonary examinations at an indium-processing factory. METHODS Data for ...
متن کاملTwo- and 13-week inhalation toxicities of indium-tin oxide and indium oxide in rats.
OBJECTIVES Two- and 13-week inhalation toxicities of indium-tin oxide (ITO) and indium oxide (IO) were characterized for risk assessments of workers exposed to ITO. METHODS F344 rats of both sexes were exposed by inhalation to ITO or IO aerosol for 6 h/day, 5 day/wk for 2 wk at 0, 0.1, 1, 10 or 100 mg/m(3) or 13 wk at 0, 0.1 or 1 mg/m(3). An aerosol generator and inhalation exposure system wa...
متن کاملExposure to hardly soluble indium compounds in ITO production and recycling plants is a new risk for interstitial lung damage.
OBJECTIVES To identify the effects of indium on the lung and to assess exposure-effect and exposure-response relations between indium exposure and effects on the lungs. METHODS Ninety three male indium exposed and 93 male non-exposed workers from four ITO manufacturing or ITO recycling plants were analysed in a cross-sectional study. Indium in serum (In-S) was determined as a biological expos...
