Silicosis is the occupational lung disease caused by inhalation of silica dust. The occupational group at highest risk is:
- A Stone quarry and sandblasting workers ✓
- B Coal miners (coal dust exposure)
- C Cotton textile workers (byssinosis risk)
- D Asbestos workers (mesothelioma risk)
Correct answer: A. Stone quarry and sandblasting workers
Explanation
Silicosis results from inhalation of crystalline silica (SiO₂) particles and is most common among stone quarry workers, sandblasters, tunnelers, and foundry workers who are exposed to high concentrations of free silica dust. Coal miners risk pneumoconiosis (coal workers' pneumoconiosis), not silicosis per se, unless the coal contains silica. Cotton workers risk byssinosis; asbestos workers risk mesothelioma and asbestosis.
