    Abstract:

    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 den Lungen-6 (KL-6) levels that were higher than the reference values set in Japan (3 μg/L and 500 U/mL, respectively). Thirty-four of the 78 workers underwent chest high-resolution computed tomography (HRCT), and their data were used for statistical analysis. Results Geometric means (geometric standard deviations) for serum Indium, KL-6, and surfactant protein D (SP-D) were 10.9 (6.65) μg/L, 859.0 (1.85) U/mL, and 179.27 (1.81) ng/mL, respectively. HRCT showed intralobular interstitial thickening in 9 workers. A dose–response trend was statistically significant for blood KL-6 levels. All workers who had Indium levels ≥50 μg/L had KL-6 levels that exceeded the reference values. However, dose–response trends for blood SP-D levels, KL-6 levels, SP-D levels, and interstitial changes on the HRCT scans were not significantly different. Conclusions Our findings suggest that interstitial lung changes could be present in workers with Indium exposure. Further studies are required and health risk information regarding Indium exposure should be communicated to workers and employers in industries where Indium Compounds are used to prevent Indium induced lung damage in Korea.

  • Thickness dependence of ZnO:In thin films doped with different Indium Compounds and deposited by chemical spray
    Solar Energy Materials and Solar Cells, 2006
    Co-Authors: M.a. Lucio-lópez, Arturo Maldonado, R. Castanedo-pérez, G. Torres-delgado, M. De La L. Olvera
    Abstract:

    Abstract Indium-doped zinc oxide thin films were deposited on glass substrates by the chemical spray technique. Hydrated zinc 2,4-pentanedionate was used as zinc source. Four different Indium Compounds were separately used as dopants (Indium nitrate, Indium sulfate, Indium acetate, and Indium chloride). The effect of the thickness on the electrical, structural, morphological and optical characteristics of ZnO:In thin films was studied. Electrical resistivity values corresponding to good conductive electrodes were obtained irrespective of the Indium Compound used, although a decrease in electrical resistivity is found in all the cases as the film thickness increases, reaching a saturation value of 2×10−3 Ω cm. All films were polycrystalline with a wurtzite phase, and exhibited a (1 0 1) preferential orientation almost irrespective of neither the doping source nor thickness. The surface morphology was analyzed by scanning electron microscopy and a strong dependence on the Indium Compound and thickness was found, since grain geometry variations from rounded to rod-like forms were observed. As the film thickness increases, the film transmittance and the band-gap values decrease. Band-gap energy values were in the range of 3.21 to 3.44 eV.
