    Coal miners exhibit abnormal lung function, specifically elevated closing volume and closing capacity, even without smoking or diagnosed pneumoconiosis. This indicates occupational lung disease risks in mining environments.

    Area of Science:

    • Occupational Medicine
    • Pulmonary Physiology
    • Environmental Health

    Background:

    • Coal mining poses risks to respiratory health.
    • Pulmonary function tests (PFTs) are crucial for assessing lung health.
    • Closing volume and closing capacity are sensitive indicators of small airway disease.

    Purpose of the Study:

    • To assess lung function abnormalities in Appalachian coal miners.
    • To investigate the relationship between dust exposure, smoking, and lung function.
    • To determine if pneumoconiosis or bronchitis correlates with closing volume/capacity changes.

    Main Methods:

    • Pulmonary function tests, including closing volume and closing capacity, were performed.
    • 82 Appalachian coal miners and control subjects were studied.

  • Data were analyzed to correlate lung function with smoking history, dust exposure, and disease presence.

    • Main Results:

    • Nonsmoking miners showed elevated closing volume and closing capacity compared to controls.
    • Smokers and ex-smokers also had elevated closing capacity.
    • No association was found between bronchitic symptoms or pneumoconiosis and elevated closing volume/capacity.

    Conclusions:

    • Coal miners experience significant small airway dysfunction, indicated by abnormal closing volumes and capacities.
    • Occupational dust exposure appears to contribute to lung function impairment, independent of smoking or diagnosed pneumoconiosis.
    • Early detection of lung function changes is vital for miners, even in the absence of overt disease symptoms.
