Small-scale metal workers show reduced ventilatory function, with 4.7% having a low forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) ratio. This highlights potential occupational lung health risks in this industry.

Area of Science:

  • Occupational Health
  • Pulmonary Medicine
  • Industrial Hygiene

Background:

  • Small-scale metal working industries pose potential respiratory health risks to workers.
  • Evaluating ventilatory function is crucial for identifying occupational lung diseases.

Purpose of the Study:

  • To assess the ventilatory function of workers in small-scale metal working industries.
  • To compare their lung function with previously reported occupational groups.

Main Methods:

  • Evaluated ventilatory function in 634 workers.
  • Measured forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, and mid/end expiratory flow rates.
  • Compared results with published data from other occupational groups.

Main Results:

  • 4.7% of workers had an FEV1/FVC ratio below 75%.
  • Metal workers exhibited lower FVC and FEV1 values compared to other occupational groups.
  • Mid and end expiratory flow rates, sensitive indicators of small airway obstruction, were also assessed.

Conclusions:

  • Workers in small-scale metal industries may have impaired lung function.
  • Further research is recommended to establish normative ventilatory function data for the general population.
  • The reported forced expiratory flow rate data can aid future investigations into airway obstructions.
