Toxics in the ‘Clean Rooms’: Are Samsung Workers at Risk?

Workers groups in South Korea report an unusually high incidence of cancers and other serious diseases among employees at Samsung’s semiconductor and other electronics plants. While the company denies any link, the pattern of illnesses is disturbingly similar to that seen at semiconductor facilities in the U.S. and Europe.

Benzene and other volatile organic compounds used widely in semiconductor and other electronics manufacturing also include trichloroethylene (TCE) and methylene chloride, which are associated with cancer and nervous system damage and are also known to affect developing embryos. Benzene is classified by the U.S. Environmental Protection Agency, the U.S. Department of Health and Human Services, and the International Agency for Research on Cancer as a confirmed human carcinogen. It is known to cause leukemia and dangerous blood disorders including aplastic anemia and thrombocytopenia, a disease that interferes with blood-clotting, from which at least one Samsung worker is suffering.
