Information and documents were reviewed which had been received from Syntex Agribusiness (SIC-2869), for a facility in Verona, Missouri operated by Hoffman-Taff and the North Eastern Pharmaceutical and Chemical Company (NEPACCO), as part of the Dioxin Registry study. During this time period Hoffman-Taff produced 2,4,5- trichlorophenoxyacetic-acid-butyl-ester (93798) and NEPACCO produced hexachlorophene (70304). Company records located at the Syntex facility in Springfield, Missouri made it possible to identify production workers and supervisors who were involved in making these compounds. Maintenance workers were also identified. These individuals have therefore been included in the Dioxin Registry. Compensation records for workers were obtained for the period 1968 to 1972 and all medical records were obtained for employees engaged in making these particular chemicals. In analyzing Agent-Orange (39277479) prepared by Hoffman-Taff, it was found to contain less than 1.0 part per million 2,3,7,8-tetrachlorodibenzo-p-dioxin (1746016) (TCDD). Analysis of samples of NEPACCO's purified 2,4,5- trichlorophenol (25167822) and hexachlorophene indicated that they contained 67 parts per billion and less than 20 parts per billion TCDD, respectively.
