Environmental air samples were taken on June 6 to 8, 1977 at the currently nonoperating Velsicol Chemical Corporation (SIC-2819) facility in St. Louis, Michigan and a medical evaluation of facility employees was conducted between October 17 and 22, 1977. The sampling and medical evaluations were prompted by a request from an authorized representative of employees of the Oil, Chemical, and Atomic Workers Union regarding past employee exposures to polybrominated-biphenyls (36355018) and current employee exposures to a variety of chemicals. Sampling results show that carbon- tetrachloride (56235), ethylene-dichloride (107062), benzene (71432), trichloroethylene (79016), total particulates, sulfur- dioxide (7446095), and ammonia (7664417) were either undetected or below OSHA standards. Two measurements of approximately 20 to 30 parts per million of air (ppm) were recorded for methyl-bromide (74839) near a halogen detecting bunsen burner. These concentrations exceeded the OSHA standard (15ppm). Medical evaluation results reveal that facility workers showed a high incidence of acneiform skin lesions, probably caused by occupational exposure to halogenated chemicals. Some employees may have had adverse health effects upon either their nervous, cardiovascular, hepatic, immune, or respiratory systems. It is recommended that exhaust and ventilation systems be improved and that engineering controls should be instituted or improved on all reactors. Workers should be informed of the extent and severity of health effects and those who show evidence of damage to the hepatic, nervous, immune, or hematologic systems should be removed from further exposure to solvents and other toxic materials.
