Work Tasks as Determinants of Respirable and Inhalable Indium Exposure among Workers at an Indium–Tin Oxide Production and Reclamation Facility

Increased global demand for touch screens, photovoltaics, and optoelectronics has resulted in an increase in the production of indium–tin oxide (ITO). Occupational exposure to indium compounds is associated with the development of indium lung disease. Although many previous epidemiologic investigations highlight an excess of lung abnormalities in workplaces where ITO is produced, few assessments of occupational exposure to respirable and...
