    Chemical workers exposed to dusts, pigments, and solvents showed impaired lung function, particularly those with long-term exposure. Cigarette smoking also significantly impacted diffusing capacity, suggesting a combined negative effect on respiratory health.

    Area of Science:

    • Occupational Medicine
    • Pulmonary Physiology

    Context:

    • Chemical workers in dye factories face exposure to mineral dusts, organic pigments, and solvents.
    • Previous studies indicate potential respiratory risks associated with such occupational exposures.

    Purpose:

    • To evaluate the impact of occupational exposure in a dye factory on lung function, specifically forced expiratory flows and carbon monoxide diffusing capacity.
    • To assess the combined effects of the working environment and smoking habits on respiratory health.

    Summary:

    • The study assessed lung function in chemical dye factory workers, finding significant differences in forced expiratory flows (FEF25-75, MEF50, MEF75) compared to reference values.
    • Reduced carbon monoxide diffusing capacity (KCO%) was primarily linked to smoking, though exercise tests showed lower than expected diffusing capacity for carbon monoxide (DLCOSS2).

  • Chronic Obstructive Lung Disease (COLD) was diagnosed in 71% of subjects with over 15 years of employment, indicating a link between long-term exposure and disease.

    • Impact:

    • Findings suggest that the working environment in dye factories negatively affects lung function, especially with medium- to long-term exposure.
    • The study highlights the synergistic negative impact of occupational exposures and cigarette smoking on the respiratory health of chemical workers.
    • Results underscore the importance of workplace safety measures and smoking cessation programs in preventing occupational lung diseases.
