Objectives: The purpose of this study is to provide current the recent information on indium-related adverse health effects and the Korean indium-related industries. Methods: Peer review papers were searched in environmental, occupational and medical journals with the keyword of 'Indium' and 'ITO' and reviewed. To determine the indium related industries and indium consumption amounts, references and database were investigated and analyzed. In addition, field walk-through surveys and interviews were conducted in order to collect field data and to ascertain the field situation for the processes and industries. Results: A total of 10 cases of indium lung diseases have been reported in series since the first case reported in 2001. Seven cases were found in Japan, two cases in the United States, and one in China. No indium lung case has been reported yet in Korea, but it is believed that there are high potential risks among workers in indium-related industries. There are four categories in indiumrelated- industry; indium production and smelting, manufacturing of indium products such as ITO target, the production of thin films of flat panel display, and indium recovery industry. We found that all these types of industries are operating in Korea. Therefore, it is necessary for industrial hygienists to understand the processes and industries related to indium as well as the adverse health effects of indium. Conclusions: It was found that all four categories of indium-related industry from the indium production to recovery industry are active in Korea. However, the adverse health effects of indium are not well recognized. Therefore, it is believed that there is a high risks in indium-related industry, and it is necessary to make emergency interventions.
