What is a classic example of a lung hazard caused by inhaled dust?

• A. Pneumoconiosis (black lung)
• B. Influenza
• C. Asthma
• D. Pleurisy

Answer: (A)

Inhaled mineral dust over time can cause a lung disease called pneumoconiosis, with black lung being the classic example. This condition develops from sustained exposure to dusts like coal, silica, or asbestos, and the particles accumulate in the lungs, triggering inflammation and fibrosis that impair lung function. It’s the textbook demonstration of a lung hazard produced by inhaled dust in industrial settings. Influenza is a viral infection, not a dust-related lung hazard. Asthma is a reactive airway disease that can be triggered by irritants but isn’t fundamentally about inhaled dust causing chronic fibrotic lung disease. Pleurisy is inflammation of the tissue surrounding the lungs and can have various causes, not specifically tied to inhaled dust exposure.
