This study assesses the health effects of underground electric utility workers who, by nature of their jobs, may have had the greatest potential for long-term exposure to PCBs found in the utility industry. The serum PCB levels of these workers ranged from 1 to 31 ppb with an arithmetic mean of 7.78 ppb, compared to the matched, nonoccupationally exposed, control population arithmetic mean of 3.56. This indicates that the workers did in fact experience exposures significantly higher than likely to be found in non-occupational settings. Even though exposure was found to be long-term, serum PCBs did not demonstrate a significant correlation with age or work experience. The correlation between serum PCB levels and liver enzymes was very weak at best even though several of the exposed population had elevated enzymes. A correlation was found between serum PCB levels and triglycerides. Other blood and urine chemistries showed no abnormalities that could be directly associated with either exposure to PCBs or with any disease process as a result of exposure to PCBs. The physical examinations were unremarkable with regard to symptoms or disease processes either caused or potentially caused by exposures to PCBs.
