    Polychlorinated biphenyl (PCB) exposure in capacitor manufacturing workers may lead to reduced lung function, specifically a restrictive spirometric impairment. This lung function change occurred without significant radiographic abnormalities in most affected individuals.

    Area of Science:

    • Occupational Medicine
    • Pulmonary Medicine
    • Toxicology

    Background:

    • Polychlorinated biphenyls (PCBs) are industrial chemicals with known toxicological effects.
    • Previous research suggests potential accumulation of PCBs and their metabolites in lung tissue.
    • Understanding the impact of occupational PCB exposure on respiratory health is crucial.

    Purpose of the Study:

    • To evaluate pulmonary function in workers with occupational exposure to PCBs.
    • To identify the prevalence and pattern of lung function impairment in this cohort.
    • To correlate spirometric findings with radiographic changes.

    Main Methods:

    • Pulmonary function tests, including Forced Vital Capacity (FVC) and FEV1/FVC ratio, were performed.
    • 243 workers with occupational PCB exposure from capacitor manufacturing were assessed.

  • Chest roentgenograms were evaluated using the ILO UC Classification.

    • Main Results:

    • 14% of workers exhibited reduced FVC (<80% of predicted).
    • 80% of those with reduced FVC showed a restrictive spirometric pattern (FEV1/FVC > 0.7).
    • Only one worker with restrictive impairment had an abnormal chest roentgenogram.

    Conclusions:

    • Occupational PCB exposure is associated with restrictive spirometric impairment.
    • Radiographic changes are uncommon despite significant lung function abnormalities.
    • These findings highlight a potential disconnect between functional and structural lung damage in PCB-exposed workers.
