The National Institute for Occupational Safety and Health (NIOSH) Dioxin Registry is a compilation of demographic and work history information for all U.S. production workers who have synthesized products known to be contaminated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and/or hexachlorodibenzo-p-dioxins (HxCDD). currently, there are fourteen production facilities and approximately 7000 workers included in the Registry. The first use of this information is a retrospective cohort mortality study for which the comparison group is the U.S. male population. This study will evaluate the causes of death among workers exposed to products contaminated with TCDD and/or HxCDD. A facility, located in Jacksonville, Arkansas, produced sodium 2,4,5-trichlorophenate (NaTCP), 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), 2,4,5-T esters and amines from 1957 to 1979. NaTCP and 2,4,5-T have been shown to be contaminated with TCDD. This facility was operated by Reasor-Hill, Incorporated from 1946 to 1961, by Hercules, Incorporated from 1962 to 1971, and by Transvaal, Inc./Vertac Chemical Company from 1971 to 1988. Presented in this report is a description of the facility, the workforce, the production processes, past exposures, and record systems. This information and data will be used as a part of the NIOSH Dioxin Registry study.
