HHE Report No. HETA-83-297-1846, Truck Terminals, St. Louis, Missouri.
NIOSH 1987 Nov:33 pages
In response to a request from the International Brotherhood of Teamsters, an evaluation was made of possible exposure to 2,3,7,8- tetrachlorodibenzo-p-dioxin (1746016) (TCDD) at trucking terminals (SIC-4231) in St. Louis, Missouri. The terminals belonged to the Jones Truck Lines, the P.J. Hamill Transfer Company, and the Overnight Transportation Company. During the 1970s these terminals were sprayed with waste oil for dust control. A self selected group of workers participated in a medical survey and provided information regarding employment and TCDD exposure history. A significant association was noted between symptoms of numbness in hands and feet, pins and needles in the extremities, insomnia and feelings of depression, and possible exposure to TCDD. One case of porphyria cutanea tarda and one of dermatofibrosarcoma were reported. The patient with porphyria cutanea tarda later developed a pelvic angiosarcoma, probably of soft tissue origin. Environmental samples taken at Jones Truck Lines revealed a dioxin concentration of about 18.7 parts per billion on the rafters inside the terminal. Dioxin was present in two surface soil samples taken near an entrance gate. The authors conclude that no definite association between TCDD exposure and symptoms or medical problems can be established. The authors recommended that measures be taken to control or eliminate possible exposures at the terminals; action was taken based on these recommendations.
