Occupational exposures to polychlorinated-biphenyls (PCBs) at the Mowbray Engineering Company (SIC-4911) in Greenville, Alabama were investigated on March 18 and 19 1981. The Company employed 12 persons. The study was requested by the Chronic Diseases Division, Center for Environmental Health, Centers for Disease Control. Soil samples of greater than 300 parts per million (ppm) PCBs had been reported adjacent to the facility. Personal and general work area samples were collected and analyzed. Medical interviews and limited physical examinations were also conducted. No PCBs were detected in air samples at the detection limit of 0.05 micrograms per sample. PCB concentrations ranged from below the detection limit to 1.9 micrograms per 100 square centimeters on wipe samples. Eye discharge and mildly injected conjunctiva were associated with longer duration of employment. Serum PCB concentrations ranged from 6 to 52 parts per billion with a mean of 22.5 parts per billion. Three of four values were within the range found in unexposed populations while the other was in the low range for occupationally exposed groups. The authors conclude that workers do not appear to be exposed to excessive amounts of PCBs. Recommendations to reduce skin exposure to transformer oil are provided.
