Construction workers exposed to quartz dust experience significant lung function loss, including obstructive and restrictive patterns. This study quantifies respiratory symptoms and lung function decreases in this occupational group.

Area of Science:

  • Occupational Health
  • Environmental Medicine
  • Pulmonary Medicine

Background:

  • The respiratory health impact of quartz dust exposure in construction workers remains largely unquantified.
  • Construction workers face potential risks from silica dust inhalation, necessitating research into associated respiratory issues.

Purpose of the Study:

  • To determine the prevalence of respiratory symptoms and lung function decline in quartz dust-exposed construction workers.
  • To associate lung function changes with radiographic abnormalities and occupational exposure levels.

Main Methods:

  • A cross-sectional study involving 1335 construction workers.
  • Assessment included spirometric lung function measurements and recording of respiratory symptoms.
  • Data were analyzed in relation to exposure levels and radiographic findings, with comparisons to a reference population.

Main Results:

  • Pneumoconiosis was linked to increased risk of low FEV1 and FVC values.
  • Construction workers exhibited slightly lower average lung function than a reference population.
  • A small reduction in FVC (5 ml/year) was observed with higher exposure levels.

Conclusions:

  • Obstructive and restrictive lung function loss was identified in construction workers exposed to quartz dust.
  • Findings highlight the need for protective measures against silica dust in the construction industry.
