NIOSH (National Institute for Occupational Safety and Health) Testimony on Dioxin by J. D. Millar on November 9, 1983.

PB90179144

Publication Date	1983
Page Count	10
Abstract	The testimony concerned studies conducted by the National Institute for Occupational Safety and Health (NIOSH) related to long term health consequences among workers exposed to dioxin (1746016) contaminated products. The Dioxin Registry and Mortality Study was summarized exploring the relationship between soft tissue sarcoma and dioxin exposure. A cohort of workers was identified through this registry who are known to have worked in chemical processes which generated dioxin. This group constitutes a unique population of persons with documentation of potential exposure to dioxin among whom meaningful epidemiological observations can be made. An extensive review was also made of medical literature concerning the link between exposure to dioxin and soft tissue sarcoma. Several clinical cases of soft tissue sarcoma were observed among Swedish lumberjacks previously exposed to dioxin contaminated products. Similar studies were conducted in the United States among workers exposed to the herbicide 2,4,5-trichlorophenoxy-acetic-acid (93765) or its chemical precursor, trichlorophenol (95954). The results of these studies were not considered to confirm a link between dioxin and soft tissue sarcoma, but they did provide sufficient reason for continuing the study.
