Recent case reports and epidemiological studies suggest that inhalation of indium dust induces lung damage. ⋯ Dose-dependent lung effects due to indium exposure were shown, and a decrease of indium exposure reduced the lung effects. An In-S value of 3 ng/ml may be a cut-off value which could be used to prevent early effects on the lungs.
