Abstract
To determine possible hazardous exposure to polychlorinated- biphenyls (1336363) (PCB), a health hazard evaluation of the Union Electric Company, ( SIC-4911) St. Louis, Missouri, was conducted. Breathing zone samples were collected from workers considered to have highest potential risk. Medical evaluations were performed using questionnaire information regarding occupational/medical histories and exogenous exposures (alcohol, tobacco, drugs). Blood and urine tests were performed. At the time of the survey employees were exposed to levels of PCB in excess of the NIOSH recommended standard but below Federal standards for PCB during transformer overhaul operations. A final report of the medical evaluation is forthcoming. In addition, employees were not exposed to toxic levels of trichlorobenzene (87616) or 1,1,1-trichloroethane (71556), during operations involving transformer oils. Herbicide spraying operations at the time of the survey produced no toxic exposures to prophylene-glycol-butyl-ether-esters.
