| Outline of Final Research Achievements |
To prevent workers from indium exposure in the workplaces of producing or handling of indium compounds including ITO, workers are mandated to effective respiratory protective equipment. The hair of workers is exposed by indium up to ug/g, but there is no attention to hair exposure.
In this study, personal breathing zone samplings and hair samplings of workers was examined for indium exposure. Indium concentrations of hair at morning and evening were increased dose-dependently to breathing zone concentrations of total indium dust, respectively. Spectroscopic analysis using synchrotron radiation by SPring-8 revealed indium chemical adsorption in the surface of hair.
